I was asked some interesting questions recently by CEO & CIO, a Chinese business magazine. The questions ranged from how Chinese Internet giants like Alibaba, Baidu and Tencent differ from other customers and what leading technologies big Internet companies have created to questions about emerging technologies such as software-defined storage (SDS) and software-defined datacenters (SDDC) and changes in the ecosystem of datacenter hardware, software and service providers. These were great questions. Sometimes you need the press or someone outside the industry to ask a question that makes you step back and think about what’s going on.
I thought you might interested, so this blog, the first of a 3-part series covering the interview, shares details of the first two questions.
CEO & CIO: In recent years, Internet companies have built ultra large-scale datacenters. Compared with traditional enterprises, they also take the lead in developing datacenter technology. From an industry perspective, what are the three leading technologies of ultra large-scale Internet data centers in your opinion? Please describe them.
There are so many innovations and important contributions to the industry from these hyperscale datacenters in hardware, software and mechanical engineering. To choose three is difficult. While I would prefer to choose hardware innovations as their big ones, I would suggest the following as they have changed our world and our industry and are changing our hardware and businesses:
Autonomous behavior and orchestration
An architect at Microsoft once told me, “If we had to hire admins for our datacenter in a normal enterprise way, we would hire all the IT admins in the world, and still not have enough.” There are now around 1 million servers in Microsoft datacenters. Hyperscale datacenters have had to develop autonomous, self-managing, sometimes self-deploying datacenter infrastructure simply to expand. They are pioneering datacenter technology for scale – innovating, learning by trial and error, and evolving their practices to drive more work/$. Their practices are specialized but beginning to be emulated by the broader IT industry. OpenStack is the best example of how that specialized knowledge and capability is being packaged and deployed broadly in the industry. At LSI, we’re working with both hyperscale and orchestration solutions to make better autonomous infrastructure.
High availability at datacenter level vs. machine level
As systems get bigger they have more components, more modes of failure and they get more complex and expensive to maintain reliability. As storage is used more, and more aggressively, drives tend to fail. They are simply being used more. And yet there is continued pressure to reduce costs and complexity. By the time hyperscale datacenters had evolved to massive scale – 100’s of thousands of servers in multiple datacenters – they had created solutions for absolute reliability, even as individual systems got less expensive, less complex and much less reliable. This is what has enabled the very low cost structures of the cloud, and made it a reliable resource.
These solutions are well timed too, as more enterprise organizations need to maintain on-premises data across multiple datacenters with absolute reliability. The traditional view that a single server requires 99.999% reliability is giving way to a more pragmatic view of maintaining high reliability at the macro level – across the entire datacenter. This approach accepts the failure of individual systems and components even as it maintains data center level reliability. Of course – there are currently operational issues with this approach. LSI has been working with hyperscale datacenters and OEMs to engineer improved operational efficiency and resilience, and minimized impact of individual component failure, while still relying on the datacenter high-availability (HA) layer for reliability.
It’s such an overused term. It’s difficult to believe the term barely existed a few years ago. The gift of Hadoop® to the industry – an open source attempt to copy Google® MapReduce and Google File System – has truly changed our world unbelievably quickly. Today, Hadoop and the other big data applications enable search, analytics, advertising, peta-scale reliable file systems, genomics research and more – even services like Apple® Siri run on Hadoop. Big data has changed the concept of analytics from statistical sampling to analysis of all data. And it has already enabled breakthroughs and changes in research, where relationships and patterns are looked for empirically, rather than based on theories.
Overall, I think big data has been one of the most transformational technologies this century. Big data has changed the focus from compute to storage as the primary enabler in the datacenter. Our embedded hard disk controllers, SAS (Serial Attached SCSI) host bus adaptors and RAID controllers have been at the heart of this evolution. The next evolutionary step in big data is the broad adoption of graph analysis, which integrates the relationship of data, not just the data itself.
CEO & CIO: Due to cloud computing, mobile connectivity and big data, the traditional IT ecosystem or industrial chain is changing. What are the three most important changes in LSI’s current cooperation with the ecosystem chain? How does LSI see the changes in the various links of the traditional ecosystem chain? What new links are worth attention? Please give some examples.
Cloud computing and the explosion of data driven by mobile devices and media has and continues to change our industry and ecosystem contributors dramatically. It’s true the enterprise market (customers, OEMs, technology, applications and use cases) has been pretty stable for 10-20 years, but as cloud computing has become a significant portion of the server market, it has increasingly affected ecosystem suppliers like LSI.
Timing: It’s no longer enough to follow Intel’s ticktock product roadmap. Development cycles for datacenter solutions used to be 3 to 5 years. But these cycles are becoming shorter. Now, demand for solutions is closer to 6 months – forcing hardware vendors to plan and execute to far tighter development cycles. Hyperscale datacenters also need to be able to expand resources very quickly, as customer demand dictates. As a result they incorporate new architectures, solutions and specifications out of cycle with the traditional Intel roadmap changes. This has also disrupted the ecosystem.
End customers: Hyperscale datacenters now have purchasing power in the ecosystem, with single purchase orders sometimes amounting to 5% of the server market. While OEMs still are incredibly important, they are not driving large-scale deployments or innovating and evolving nearly as fast. The result is more hyperscale design-win opportunities for component or sub-system vendors if they offer something unique or a real solution to an important problem. This also may shift profit pools away from OEMs to strong, nimble technology solution innovators. It also has the potential to reduce overall profit pools for the whole ecosystem, which is a potential threat to innovation speed and re-investment.
New players: Traditionally, a few OEMs and ISVs globally have owned most of the datacenter market. However, the supply chain of the hyperscale cloud companies has changed that. Leading datacenters have architected, specified or even built (in Google’s case) their own infrastructure, though many large cloud datacenters have been equipped with hyperscale-specific systems from Dell and HP. But more and more systems built exactly to datacenter specifications are coming from suppliers like Quanta. Newer network suppliers like Arista have increased market share. Some new hyperscale solution vendors have emerged, like Nebula. And software has shifted to open source, sometimes supported for-pay by companies copying the Redhat® Linux model – companies like Cloudera, Mirantis or United Stack. Personally, I am still waiting for the first 3rd-party hardware service emulating a Linux support and service company to appear.
Open initiatives: Yes, we’ve seen Hadoop and its derivatives deployed everywhere now – even in traditional industries like oil and gas, pharmacology, genomics, etc. And we’ve seen the emergence of open-source alternatives to traditional databases being deployed, like Casandra. But now we’re seeing new initiatives like Open Compute and OpenStack. Sure these are helpful to hyperscale datacenters, but they are also enabling smaller companies and universities to deploy hyperscale-like infrastructure and get the same kind of automated control, efficiency and cost structures that hyperscale datacenters enjoy. (Of course they don’t get fully there on any front, but it’s a lot closer). This trend has the potential to hurt OEM and ISV business models and markets and establish new entrants – even as we see Quanta, TYAN, Foxconn, Wistron and others tentatively entering the broader market through these open initiatives.
New architectures and new algorithms: There is a clear movement toward pooled resources (or rack scale architecture, or disaggregated servers). Developing pooled resource solutions has become a partnership between core IP providers like Intel and LSI with the largest hyperscale datacenter architects. Traditionally new architectures were driven by OEMs, but that is not so true anymore. We are seeing new technologies emerge to enable these rack-scale architectures (RSA) – technologies like silicon photonics, pooled storage, software-defined networks (SDN), and we will soon see pooled main memory and new nonvolatile main memories in the rack.
We are also seeing the first tries at new processor architectures about to enter the datacenter: ARM 64 for cool/cold storage and web tier and OpenPower P8 for high power processing – multithreaded, multi-issue, pooled memory processing monsters. This is exciting to watch. There is also an emerging interest in application acceleration: general-purposing computing on graphics processing units (GPGPUs), regular expression processors (regex) live stream analytics, etc. We are also seeing the first generation of graph analysis deployed at massive scale in real time.
Innovation: The pace of innovation appears to be accelerating, although maybe I’m just getting older. But the easy gains are done. On one hand, datacenters need exponentially more compute and storage, and they need to operate 10x to 1000x more quickly. On the other, memory, processor cores, disks and flash technologies are getting no faster. The only way to fill that gap is through innovation. So it’s no surprise there are lots of interesting things happening at OEMs and ISVs, chip and solution companies, as well as open source community and startups. This is what makes it such an interesting time and industry.
Consumption shifts: We are seeing a decline in laptop and personal computer shipments, a drop that naturally is reducing storage demand in those markets. Laptops are also seeing a shift to SSD from HDD. This has been good for LSI, as our footprint in laptop HDDs had been small, but our presence in laptop SSDs is very strong. Smart phones and tablets are driving more cloud content, traffic and reliance on cloud storage. We have seen a dramatic increase in large HDDs for cloud storage, a trend that seems to be picking up speed, and we believe the cloud HDD market will be very healthy and will see the emergence of new, cloud-specific HDDs that are radically different and specifically designed for cool and cold storage.
There is also an explosion of SSD and PCIe flash cards in cloud computing for databases, caches, low-latency access and virtual machine (VM) enablement. Many applications that we take for granted would not be possible without these extreme low-latency, high-capacity flash products. But very few companies can make a viable storage system from flash at an acceptable cost, opening up an opportunity for many startups to experiment with different solutions.
Summary: So I believe the biggest hyperscale innovations are autonomous behavior and orchestration, HA at the datacenter level vs. machine level, and big data. These are radically changing the whole industry. And what are those changes for our industry and ecosystem? You name it: timing, end customers, new players, open initiatives, new architectures and algorithms, innovation, and consumption patterns. All that’s staying the same are legacy products and solutions.
These were great questions. Sometimes you need the press or someone outside the industry to ask a question that makes you step back and think about what’s going on. Great questions.

It’s the start of the new year, and it’s traditional to make predictions – right? But predicting the future of the datacenter has been hard lately. There have been and continue to be so many changes in flight that possibilities spin off in different directions. Fractured visions through a kaleidoscope. Changes are happening in the businesses behind datacenters, the scale, the tasks and what is possible to accomplish, the value being monetized, and the architectures and technologies to enable all of these.
A few months ago I was asked to describe the datacenter in 2020 for some product planning purposes. Dave Vellante of Wikibon & John Furrier of SiliconANGLE asked me a similar question a few weeks ago. 2020 is out there – almost 7 years. It’s not easy to look into the crystal ball that far and figure out what the world will look like then, especially when we are in the midst of those tremendous changes. For some context I had to think back 7 years – what was the datacenter like then, and how profound have the changes been over the past 7 years?
And 7 years ago, our forefathers…
It was a very different world. Facebook barely existed, and had just barely passed the “university only” membership. Google was using Velcro, Amazon didn’t have its services, cloud was a non-existent term. In fact DAS (direct attach storage) was on the decline because everyone was moving to SAN/NAS. 10GE networking was in the future (1GE was still in growth mode). Linux was not nearly as widely accepted in enterprise – Amazon was in the vanguard of making it usable at scale (with Werner Vogels saying “it’s terrible, but it’s free, as in free beer”). Servers were individual – no “PODs,” and VMware was not standard practice yet. SATA drives were nowhere in datacenters.
An enterprise disk drive topped out at around 200GB in capacity. Nobody used the term petabyte. People, including me, were just starting to think about flash in datacenters, and it was several years later that solutions became available. Big data did not even exist. Not as a term or as a technology, definitely not Hadoop or graph search. In fact, Google’s seminal paper on MapReduce had just been published, and it would become the inspiration for Hadoop – something that would take many years before Yahoo picked it up and helped make it real.
Analytics were statistical and slow, and you had to be very explicitly looking for something. Advertising on the web was a modest business. Cold storage was tape or MAID, not vast pools of cheap disks in the cloud at absurdly low price points. None of the Chinese web-cloud guys existed… In truth, at LSI we had not even started looking at or getting to know the web datacenter guys. We assumed they just bought from OEMs…
No one streamed mainstream media – TV and movies – and there were no tablets to stream them to. YouTube had just been purchased by Google. Blu-ray was just getting started and competing with HD-DVD (which I foolishly bought 7 years ago), and integrated GPS’s in your car were a high-tech growth area. The iPhone or Android had not launched, Danger’s Sidekick was the cool phone, flip phones were mainstream, there was no App store or the billions of sales associated with that, and a mobile web browser was virtually useless.
Dell, IBM, and HP were the only real server companies that mattered, and the whole industry revolved around them, as well as EMC and NetApp for storage. Cisco, Lenovo and Huawei were not server vendors. And Sun was still Sun.
7 years from now
So – 7 years from now? That’s hard to predict, so take this with a grain of salt… There are many ways things could play out, especially when global legal, privacy, energy, hazardous waste recycling, and data retention requirements come into play, not to mention random chaos and invention along the way.
Compute-centric to dataflow-centric
Major applications are changing (have changed) from compute-centric to dataflow architectures. That is big data. The result will probably be a decline in the influence of processor vendors, and the increased focus on storage, network and memory, and optimized rack-level architectures. A handful of hyperscale datacenters are leading the way, and dragging the rest of us along. These types of solutions are already being deployed in big enterprise for specialized use cases, and their adoption will only increase with time. In 7 years, the main deployment model will echo what hyperscale datacenters are doing today: disaggregated racks of compute, memory and storage resources.
The datacenter is now being viewed as a profit growth enabler, rather than a cost center. That implies more compute = more revenue. That changes the investment profile and the expectations for IT. It will not be enough for enterprise IT departments to minimize change and risk because then they would be slowing revenue growth.
Customers and vendors
We are in the early stages of a customer revolt. Whether it’s deserved or not is immaterial, though I believe it’s partially deserved. Large customers have decided (and I’m doing broad brush strokes here) that OEMs are charging them too much and adding “features” that add no value and burn power, that the service contracts are excessively expensive and that there is very poor management interoperability among OEM offerings – on purpose to maintain vendor lockin. The cost structures of public cloud platforms like Amazon are proof there is some merit to the argument. Management tools don’t scale well, and require a lot of admin intervention. ISVs are seen as no better. Sure the platforms and apps are valuable and critical, but they’re really expensive too, and in a few cases, open source solutions actually scale better (though ISVs are catching up quickly).
The result? We’re seeing a push to use whitebox solutions that are interoperable and simple. Open source solutions – both software and hardware – are gaining traction in spite of their problems. Just witness the latest Open Compute Summit and the adoption rate of Hadoop and OpenStack. In fact many large enterprises have a policy that’s pretty much – any new application needs to be written for open source platforms on scale-out infrastructure.
Those 3 OEMs are struggling. Dell, HP and IBM are selling more servers, but at a lower revenue. Or in the case of IBM – selling the business. They are trying to upsell storage systems to offset those lost margins, and they are trying to innovate and vertically integrate to compensate for the changes. In contrast we’re seeing a rapid increase planned from self-built, self-architected hyperscale datacenters, especially in China. To be fair – those pressures on price and supplier revenue are not necessarily good for our industry. As well, there are newer entrants like Huawei and Cisco taking a noticeable chunk of the market, as well as an impending growth of ISV and 3rd party full rack “shrink wrapped” systems. Everybody is joining the party.
Storage, cold storage and storage-class memory
Stepping further out on the limb, I believe (but who really knows) that by 2020 storage as we know is no longer shipping. SMB is hollowed out to the cloud – that is – why would any small business use anything but cloud services? The costs are too compelling. Cloud storage is stratified into 3 levels: storage-class memory, flash/NVM and cool/cold bulk disk storage. Cold storage is going to be a very, very important area. You need to save that data, but spend zero power, and zero $ on storing it. Just look at some of the radical ideas like Facebook’s Blu-ray jukebox to address that, which was masterminded by a guy I really like – Gio Coglitore – and I am very glad is getting some rightful attention. (http://www.wired.com/wiredenterprise/2014/02/facebook-robots/)
I believe that pooled storage class memory is inevitable and will disrupt high-performance flash storage, probably beginning in 2016. My processor architect friends and I have been daydreaming about this since 2005. That disruption’s OK, because flash use will continue to grow, even as disk use grows. There is just too much data. I’ve seen one massive vendor’s data showing average servers are adding something like 0.2 hard disks per year and 0.1 SSDs per year – and that’s for the average server including diskless nodes that are usually the most common in hyperscale datacenters. So growth in spite of disruption and capacity growth.
Data will be pooled, and connected by fabric as distributed objects or key/value pairs, with erasure coding. In fact, Object store (key/value – whatever) may have “obsoleted” block storage. And the need for these larger objects will probably also obsolete file as we’re used to it. Sure disk drives may still be block based, though key/value gives rise to all sorts of interesting opportunities to support variable size structures, obscure small fault domains, and variable encryption/compression without wasting space on disk platters. I even suspect that disk drives as we know them will be morphing into cold store specialty products that physically look entirely different and are made from different materials – for a lot of reasons. 15K drives will be history, and 10K drives may too. In fact 2” drives may not make sense anymore as the laptop drive and 15K drive disappear and performance and density are satisfied by flash.
Enterprise becomes private cloud that is very similar structurally to hyperscale, but is simply in an internal facility. And SAN/NAS products as we know them will be starting on the long end of the tail as legacy support products. Sure new network based storage models are about to emerge, but they’re different and more aligned to key/value.
Rack-scale architectures will have taken over clustered deployments. That means pooled resources. Processing will be pools of single socket SoC servers enabling massive clusters, rather than lots of 2- socket servers. These SoCs might even be mobile device SoCs at some point or at least derived from that – the economics of scale and fast cadence of consumer SoCs will make that interesting, maybe even inevitable. After all, the current Apple A7 in the iphone 5S is a dual core, 64-bit V8 ARM at 1.4GHz and the whole iPhone costs as much as mainstream server processor chips. In a few years, an 8 or 16 core equivalent at 1.5GHz or 2GHz is not hard to imagine, and the cost structure should be excellent.
Rapidly evolving open source applications will have morphed into eventually consistent dataflow tasks. Or they will be emerging in-memory applications working on vast data structures in the pooled storage class memory at the rack or larger scale, which will add tremendous monetary value to businesses. Whatever the evolutionary paths – the challenge for the next 10 years is optimizing dataflow as the amount used continues to exponentially grow. After all – data has value in aggregate, so why would you throw anything away, even as the amount we generate increases?
Clusters will be autonomous. Really autonomous. As in a new term I love: “emergent.” It’s when you can start using big data analytics to monitor the datacenter, and make workload/management and data placement decisions in real time, automatically, and the datacenter begins to take on un-predicted characteristics. Deployment will be autonomous too. Power on a pod of resources, and it just starts working. Google does that already.
Layer 2 datacenter network switches will either be disappearing or will have migrated to a radically different location in the rack hierarchy. There are many ways this can evolve. I’m not sure which one(s) will dominate, but I know it will look different. And it will have different bandwidth. 100G moving to 400G interconnect fabric over fiber.
So there you have it. Guaranteed correct…
Different applications and dataflow, different architectures, different processors, different storage, different fabrics. Probably even a re-alignment of vendors.
Predicting the future of the datacenter has not been easy. There have been, and are so many changes happening. The businesses behind them. The scale, the tasks and what is possible to accomplish, the value being monetized, and the architectures and technologies to enable all of these. But at least we have some idea what’s ahead. And it’s pretty different, and exciting.

Open Compute and OpenStack are changing the datacenter world that we know and love. I thought they were having impact. Changing our OEMs and ODM products, changing what we expect from our vendors, changing the interoperability of managing infrastructure from different vendors. Changing our ability to deploy and manage grid and scale-out infrastructure. And changing how quickly and at what high level we can be innovating. I was wrong. It’s happening much more quickly than I thought.
On November 20-21 we hosted LSI AIS 2013. As I mentioned in a previous post, I was lucky enough to moderate a panel about Open Compute and OpenStack – “the perfect storm.” Truthfully? It felt more like sitting with two friends talking about our industry over beer. I hope to pick up that conversation again someday.
The panelists were awesome: Cole Crawford of Open Compute and Chris Kemp of OpenStack. These guys are not only influential. They have been involved from the very start of these two initiatives, and are in many ways key drivers of both movements. These are impressive, passionate guys who really are changing the world. There aren’t too many of us who can claim that. It was an engaging hour that I learned quite a bit from, and I think the audience did too. I wanted to share from my notes what I took away from that panel. I think you’ll be interested.
Goals and Vision: two “open source” initiatives
There were a few motivations behind Open Compute, and the goal was to improve these things.
The goal then, for the first time, is to work backwards from workload and create open source hardware and infrastructure that is openly available and designed from the start for large scale-out deployments. The idea is to drive high efficiency in cost, materials use and energy consumption. More work/$.
One surprising thing that came up – LSI is in every current contribution in Open Compute.
OpenStack layers services that describe abstractions of computer networking and storage. LSI products tend to sit at that lowest level of abstraction, where there is now a wave of innovation. OpenStack had similar fragmentation issues to deal with and its goals are something like:
There is a certain amount of compatibility with Amazon’s cloud services. Chris’s point was that Amazon is incredibly innovative and a lot of enterprises should use it, but OpenStack enables both service providers and private clouds to compete with Amazon, and it allows unique innovation to evolve on top of it.
OpenStack and Open Compute are not products. They are “standards” or platform architectures, with companies using those standards to innovate on top of them. The idea is for one company to innovate on another’s improvements – everybody building on each other’s work. A huge brain trust. The goal is to create a competitive ecosystem and enable a rapid pace of innovation, and enable large-scale, inexpensive infrastructure that can be managed by a small team of people, and can be managed like a single server to solve massive scale problems.
Here’s their thought. Hardware is a supply chain management game + services. Open Compute is an opportunity for anyone to supply that infrastructure. And today, OEMs are killer at that. But maybe ODMs can be too. Open Compute allows innovation on top of the basic interoperable platforms. OpenStack enables a framework for innovation on top as well: security, reliability, storage, network, performance. It becomes the enabler for innovation, and it provides an “easy” way for startups to plug into a large, vibrant ecosystem. And for customers – someone said its “exa data without exadollar”…
As a result, the argument is this should be good for OEMs and ISVs, and help create a more innovative ecosystem and should also enable more infrastructure capacity to create new and better services. I’m not convinced that will happen yet, but it’s a laudable goal, and frankly that promise is part of what is appealing to LSI.
Open Compute and OpenStack are “peanut butter and jelly”
Ok – if you’re outside of the US, that may not mean much to you. But if you’ve lived in the US, you know that means they fit perfectly, and make something much greater together than their humble selves.
Graham Weston, Chairman of the Rackspace Board, was the one who called these two “peanut butter and jelly.”
Cole and Chris both felt the initiatives are co-enabling, and probably co-travelers too. Sure they can and will deploy independently, but OpenStack enables the management of large scale clusters, which really is not easy. Open Compute enables lower cost large-scale manageable clusters to be deployed. Together? Large-scale clusters that can be installed and deployed more affordably, and easily without hiring a cadre of rare experts.
Personally? I still think they are both a bit short of being ready for “prime time” – or broad deployment, but Cole and Chris gave me really valid arguments to show me I’m wrong. I guess we’ll see.
US or global vision?
I asked if these are US-centric or global visions. There were no qualms – these are global visions. This is just the 3rd anniversary of OpenStack, but even so, there are OpenStack organizations in more than 100 countries, 750 active contributors, and large-scale deployments in datacenters that you probably use every day – especially in China and the US. Companies like PayPal and Yahoo, Rackspace, Baidu, Sina Weibo, Alibaba, JD, and government agencies and HPC clusters like CERN, NASA, and China Defense.
Open Compute is even younger – about 2 years old. (I remember – I was invited to the launch). Even so, most of Facebook’s infrastructure runs on Open Compute. Two Wall Street banks have deployed large clusters, with more coming, and Riot Games, which uses Open Compute infrastructure, drives 3% of the global network traffic with League of Legends. (A complete aside – one of my favorite bands to workout with did a lot of that game’s music, and the live music at the League of Legends competition a few months ago: http://www.youtube.com/watch?v=mWU4QvC09uM – not for everyone, but I like it.)
Both Cole and Chris emailed me more data after the fact on who is using these initiatives. I have to say – they are right. It really has taken off globally, especially OpenStack in the fast-paced Chinese market this year.
Book: 4th Paradigm – A tribute to computer science researcher Jim Grey
Cole and Chris mentioned a book during the panel discussion. A book I had frankly never heard of. It’s called the 4th Paradigm. It was a series of papers dedicated to researcher Jim Grey, who was a quiet but towering figure that I believe I met once at Microsoft Research. The book was put together by Gordon Bell, someone who I have met, and have profound respect for. And there are mentions of people, places, and things that have been woven through my (long) career. I think I would sum up its thesis in a quote from Jim Grey near the start of the book:
“We have to do better producing tools to support the whole research cycle – from data capture and data curation to data analysis and data visualization.”
This is stunningly similar to the very useful big data framework we have been using recently at LSI: ”capture, hold, analyze”… I guess we should have added visualize, but that doesn’t have too much to do with LSI’s business.
As an aside, I would recommend this book for the background and inspiration in why we as an industry are trying to solve many of these computer science problems, and how transformational the impact might be. I mean really transformational in the world around us, what we know, what we can do, and how quickly we can do it – which is tightly related to our CEO’s keynote and the vision video at AIS.
Demos at AIS: “peanut butter and jelly” - and bread?
Ok – I’m struggling for analogy. We had an awesome demo at AIS that Chris and Cole pointed out during the panel. It was originally built using Nebula’s TOR appliance, Open Compute hardware, and LSI’s storage magic to make it complete. The three pieces coming together. Tasty. The Open Compute hardware was swapped out last minute (for safety, those boxes were meant for the datacenter – not the showcase in a hotel with tipsy techies) and were generously supplied by Supermicro.
I don’t think the proto was close to any one of our visions, but even as it stood, it inspireda lot of people, and would make a great product. A short rack of servers, with pooled storage in the rack, OpenStack orchestrating the point and click spawning and tear down of dynamically sized LUNs of different characteristics under the Cinder presentation layer, and deployment of tasks or VMs on them.
We’re working on completing our joint vision. I think the industry will be very impressed when they see it. Chris thinks people will be stunned, and the industry will be changed.
Catalyzing the market… The future may be closer than we think…
Ultimately, this is all about economics. We’re in the middle of an unprecedented bifurcation in IT use. On one hand we’re running existing apps on new, dense enterprise hardware using VMs to layer many applications on few servers. On the other, we’re investing in applications to run at scale across inexpensive clusters of commodity hardware. This has spawned a split in IT vendor business units, product lines and offerings, and sometimes even IT infrastructure management in the datacenter.
New applications and services are needing more infrastructure, and are getting more expensive to power, cool, purchase, run. And there is pressure to transform the datacenter from a cost center into a profit center. As these innovations start, more companies will need scale infrastructure, arguably Open Compute, and then will need an Openstack framework to deploy it quickly.
Whats this mean? With a combination of big data and mobile device services driving economic value, we may be at the point where these clusters start to become mainstream. As an industry we’re already seeing a slight decline in traditional IT equipment sales and a rapid growth in scale-out infrastructure sales. If that continues, then OpenStack and Open Compute are a natural fit. The deployment rate uptick in life sciences, oil and gas, financials this year – really anywhere there is large-scale Hadoop, big data or analytics – may be the start of that growth curve. But both Chris and Cole felt it would probably take 5 years to truly take off.
Time to Wrap Up
I asked Chris and Cole for audience takeaways. Theirs were pretty simple, though possibly controversial in an industry like ours.
Hardware vendors should think about products and how they interface and what abstractions they present and how they fit into the ecosystem. These new ecosystems should allow them to easily plug in. For example, storage under Cinder can be quickly and easily morphed – that’s what we did with our demo.
We should be designing new software to run on distributed scale-out systems in clouds. Chris went on to say their code name was “Maestro” because it orchestrates like in a symphony, bringing things together in a beautiful way. He said “make instruments for the artists out there.” The brain trust. Look for their brushstrokes.
Innovate in the open, and leverage the open initiatives that are available to accelerate innovation and efficiency.
On your next IT purchase, try an RFP with an Open Compute vendor. Cole said you might be surprised. Worst case, you may get a better deal from your existing vendor.
So, Open Compute and Openstack are changing the datacenter world that we know and love. I thought these were having a quick impact, changing our OEMs and ODM products, changing what we expect from our vendors, changing the interoperability of managing infrastructure from different vendors, changing our ability to deploy and manage grid and scale-out infrastructure, and changing how quickly and at what high level we can be innovating. I was wrong. It’s happening much more quickly than even I thought.

You might be surprised to find out how big the infrastructure for cloud and Web 2.0 is. It is mind-blowing. Microsoft has acknowledged packing more than 1 million servers into its datacenters, and by some accounts that is fewer than Google’s massive server count but a bit more than Amazon.
Facebook’s server count is said to have skyrocketed from 30,000 in 2012 to 180,000 just this past August, serving 900 million plus users. And the social media giant is even putting its considerable weight behind the Open Compute effort to make servers fit better in a rack and draw less power. The list of mega infrastructures also includes Tencent, Baidu and Alibaba and the roster goes on and on.
Even more jaw-dropping is that almost 99.9% of these hyperscale infrastructures are built with servers featuring direct-attached storage. That’s right – they do the computing and store the data. In other words, no special, dedicated storage gear. Yes, your Facebook photos, your Skydrive personal cloud and all the content you use for entertainment, on-demand video and gaming data are stored inside the server.
Direct-attached storage reigns supreme
Everything in these infrastructures – compute and storage – is built out of x-86 based servers with storage inside. What’s more, growth of direct-attached storage is many folds bigger than any other storage deployments in IT. Rising deployments of cloud, or cloud-like, architectures are behind much of this expansion.
The prevalence of direct-attached storage is not unique to hyperscale deployments. Large IT organizations are looking to reap the rewards of creating similar on-premise infrastructures. The benefits are impressive: Build one kind of infrastructure (server racks), host anything you want (any of your properties), and scale if you need to very easily. TCO is much less than infrastructures relying on network storage or SANs.
With direct-attached you no longer need dedicated appliances for your database tier, your email tier, your analytics tier, your EDA tier. All of that can be hosted on scalable, share-nothing infrastructure. And just as with hyperscale, the storage is all in the server. No SAN storage required.
Open Compute, OpenStack and software-defined storage drive DAS growth
Open Compute is part of the picture. A recent Open Compute show I attended was mostly sponsored by hyperscale customers/suppliers. Many big-bank IT folks attended. Open Compute isn’t the only initiative driving growing deployments of direct-attached storage. So is software-defined storage and OpenStack. Big application vendors such as Oracle, Microsoft, VMware and SAP are also on board, providing solutions that support server-based storage/compute platforms that are easy and cost-effective to deploy, maintain and scale and need no external storage (or SAN including all-flash arrays).
So if you are a network-storage or SAN manufacturer, you have to be doing some serious thinking (many have already) about how you’re going to catch and ride this huge wave of growth.

You may have noticed I’m interested in Open Compute. What you may not know is I’m also really interested in OpenStack. You’re either wondering what the heck I’m talking about or nodding your head. I think these two movements are co-dependent. Sure they can and will exist independently, but I think the success of each is tied to the other. In other words, I think they are two sides of the same coin.
Why is this on my mind? Well – I’m the lucky guy who gets to moderate a panel at LSI’s AIS conference, with the COO of Open Compute, and the founder of OpenStack. More on that later. First, I guess I should describe my view of the two. The people running these open-source efforts probably have a different view. We’ll find that out during the panel.
I view Open Compute as the very first viable open-source hardware initiative that general business will be able to use. It’s not just about saving money for rack-scale deployments. It’s about having interoperable, multi-source systems that have known, customer-malleable – even completely customized and unique – characteristics including management. It also promises to reduce OpEx costs.
Ready for Prime Time?
But the truth is Open Compute is not ready for prime time yet. Facebook developed almost all the designs for its own use and gifted them to Open Compute, and they are mostly one or two generations old. And somewhere between 2,000 and 10,000 Open Compute servers have shipped. That’s all. But, it’s a start.
More importantly though, it’s still just hardware. There is still a need to deploy and manage the hardware, as well as distribute tasks, and load balance a cluster of Open Compute infrastructure. That’s a very specialized capability, and there really aren’t that many people who can do that. And the hardware is so bare bones – with specialized enclosures, cooling, etc – that it’s pretty hard to deploy small amounts. You really want to deploy at scale – thousands. If you’re deploying a few servers, Open Compute probably isn’t for you for quite some time.
I view OpenStack in a similar way. It’s also not ready for prime time. OpenStack is an orchestration layer for the datacenter. You hear about the “software defined datacenter.” Well, this is it – at least one version. It pools the resources (compute, object and block storage, network, and memory at some time in the future), presents them, allows them to be managed in a semi-automatic way, and automates deployment of tasks on the scaled infrastructure. Sure there are some large-scale deployments. But it’s still pretty tough to deploy at large scale. That’s because it needs to be tuned and tailored to specific hardware. In fact, the biggest datacenters in the world mostly use their own orchestration layer. So that means today OpenStack is really better at smaller deployments, like 50, 100 or 200 server nodes.
The synergy – 2 sides of the same coin
You’ll probably start to see the synergy. Open Compute needs management and deployment. OpenStack prefers known homogenous hardware or else it’s not so easy to deploy. So there is a natural synergy between the two. It’s interesting too that some individuals are working on both… Ultimately, the two Open initiatives will meet in the big, but not-too-big (many hundreds to small thousands of servers) deployments in the next few years.
And then of course there is the complexity of the interaction of for-profit companies and open-source designs and distributions. Companies are trying to add to the open standards. Sometimes to the betterment of standards, but sometimes in irrelevant ways. Several OEMs are jumping in to mature and support OpenStack. And many ODMs are working to make Open Compute more mature. And some companies are trying to accelerate the maturity and adoption of the technologies in pre-configured solutions or appliances. What’s even more interesting are the large customers – guys like Wall Street banks – that are working to make them both useful for deployment at scale. These won’t be the only way scaled systems are deployed, but they’re going to become very common platforms for scale-out or grid infrastructure for utility computing.
Here is how I charted the ecosystem last spring. There’s not a lot of direct interaction between the two, and I know there are a lot of players missing. Frankly, it’s getting crazy complex. There has been an explosion of players, and I’ve run out of space, so I’ve just not gotten around to updating it. (If anyone engaged in these ecosystems wants to update it and send me a copy – I’d be much obliged! Maybe you guys at Nebula ? ;-)).
An AIS keynote panel – What?
Which brings me back to that keynote panel at AIS. Every year LSI has a conference that’s by invitation only (sorry). It’s become a pretty big deal. We have some very high-profile keynotes from industry leaders. There is a fantastic tech showcase of LSI products, partner and ecosystem company’s products, and a good mix of proof of concepts, prototypes and what-if products. And there are a lot of breakout sessions on industry topics, trends and solutions. Last year I personally escorted an IBM fellow, Google VPs, Facebook architects, bank VPs, Amazon execs, flash company execs, several CTOs, some industry analysts, database and transactional company execs…
It’s a great place to meet and interact with peers if you’re involved in the datacenter, network or cellular infrastructure businesses. One of the keynotes is actually a panel of 2. The COO of Open Compute, Cole Crawford, and the co-founder of OpenStack, Chris Kemp (who is also the founder and CSO of Nebula). Both of them are very smart, experienced and articulate, and deeply involved in these movements. It should be a really engaging, interesting keynote panel, and I’m lucky enough to have a front-row seat. I’ll be the moderator, and I’m already working on questions. If there is something specific you would like asked, let me know, and I’ll try to accommodate you.

Yea – I’m very interested in Open Compute and OpenStack. I think these two movements are co-dependent. And I think they are already changing our industry – even before they are ready for real large-scale deployment. Sure they can and will exist independently, but I think the success of each is tied to the other. The people running these open-source efforts might have a different view. Luckily, we’ll get to find out what they think next month… And I’m lucky enough to have a front row seat.
