With the much anticipated launch of 12gb/s SAS MegaRAID and 12Gb/s SAS expanders featuring DataBolt™ SAS bandwidth-aggregation technologies, LSI is taking the bold step of moving beyond traditional IO performance benchmarks like IOMeter to benchmarks that simulate real-world workloads.
In order to fully illustrate the actual benefit many IT administrators can realize using 12Gb/s SAS MegaRAID products on their new server platforms, LSI is demonstrating application benchmarks on top of actual enterprise applications at AIS.
For our end-to-end 12Gb/s SAS MegaRAID demonstration, we chose Benchmark Factory® for Databases running on a MySQL Database.
The staggering growth of smart phones, tablets and other mobile devices is sending a massive flood of data through today’s mobile networks. Compared to just a few years ago, we are all producing and consuming far more videos, photos, multimedia and other digital content, and spending more time in immersive and interactive applications such as video and other games – all from handheld devices.
Think of mobile, and you think remote – using a handheld when you’re out and about. But according to the Cisco® VNI Mobile Forecast 2013, while 75% of all videos today are viewed on mobile devices by 2017, 46% of mobile video will be consumed indoors (at home, at the office, at the mall and elsewhere).
LSI’s Accelerating Innovation Summit in San Jose has given me a sneak peak of some solutions our partners are putting together to solve datacenter challenges. Such is the case with EMC’s ScaleIO business unit (EMC recently acquired ScaleIO), which has rolled out some nifty software that helps streamline VDI (Virtual Desktop Infrastructure) scaling.
As I shared in a previous blog, VDI deployments are growing like gangbusters. It’s easy to see why. The manageability and security benefits of virtualized desktop environment are tough to beat.
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.
Back in the 1990s, a new paradigm was forced into space exploration. NASA faced big cost cuts. But grand ambitions for missions to Mars were still on its mind. The problem was it couldn’t dream and spend big. So the NASA mantra became “faster, better, cheaper.” The idea was that the agency could slash costs while still carrying out a wide variety of programs and space missions. This led to some radical rethinks, and some fantastically successful programs that had very outside-the-box solutions.
All NAND flash-based SSDs use a process called garbage collection (GC) so the flash memory can be rewritten with fresh data, enabling the SSD to function like any other rewritable storage device. The number of rewrites (program/erase cycles) possible with NAND flash memory is finite. That’s why it’s essential to ensure that each P/E cycle really counts – that is, each is performed with top efficiency – to help preserve optimum SSD performance.
Collecting the garbage takes time
In my 2011 Flash Memory Summit presentation , I went into great detail about how GC – the automatic memory management process of clearing invalid data from memory to give new data a clean slate – works in an SSD.
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.
Where did my email go?
This week I was dragged into to the virtualized cloud kicking and screaming … well, sort of. LSI has moved me, and all my co-workers, from my nice, safe local Exchange server to one in the amorphous, mysterious cloud. Scary. My IT department says the new cloud email is a great thing. They are now promising me unlimited email storage. Long gone will be the days of harrowing emails telling me I am approaching my storage limit and soon will be unable to send new email.
Most consumers are skeptical when they see a manufacturer whipping out grandiose performance claims. And for good reason. The manufacturer could be stretching the truth, twisting the results, or just being downright misleading. From this distrust grew demand for 3rd-party writers to review products, test claims and provide an unbiased analysis of the device’s performance and other capabilities – as consumers would experience themselves.
Who can really claim to be an SSD benchmarking expert?
Solid state drive (SSD) technology is still relatively new in the computer industry, and in many ways SSDs are profoundly different from hard disk drives – perhaps most notably, in the way they record data, to a NAND cell rather than on spinning media.
The United Nations finding that mobile broadband subscriptions are surging in developing countries, reported by The New York Times on Sept. 26, is no surprise. Equally unsurprising, the growing number of users, density of users and increasing bandwidth needs of applications likely are continuing to strain existing wireless networks and per-user bandwidths not only in developing countries but worldwide.
But rising pressure on bandwidth, coupled with increasingly data-intensive applications, isn’t the whole story. Minimizing end-to-end latency – from user to network base station and back again – is crucial in enabling banking, e-commerce, enterprise and other important business applications.
