Most users have no idea that reading electronic information from a data storage medium like a hard disk drive (HDD) or solid state drive (SSD) is plagued with read errors. For this reason error correction codes (ECC) are used to fix the random bit errors that arise during the reading process before the incorrect data is returned to the user. But the error correction codes can only handle so many errors at one time. If data errors exceed the ECC limits, the data goes uncorrected and is lost forever.
Last week at LSI’s annual Accelerating Innovation Summit (AIS) the company took the wraps off a vision that should lead its technical direction for the next few years.
The LSI keynote featured a video of three situations as they might evolve in the future:
I’ll focus on just one of these to show how LSI expects the future to develop.
The problem with multicore processors isn’t that they have a lot of cores. I hope my IC designer colleagues don’t jump me when I say that having more than one core on a chip is a simple matter of cut and paste. The tricky part is getting all those cores to work together – a coordinated, efficient effort is key. After all, if it were enough for the cores to work independently, we would just use multiple single-core processors. To be sure, the devil is in the details of connecting cores and managing how they share resources.
Pushing your enterprise cluster solution to deliver the highest performance at the lowest cost is key in architecting scale-out datacenters. Administrators must expand their storage to keep pace with their compute power as capacity and processing demands grow.

The lifeblood of any online retailer is the speed of its IT infrastructure. Shoppers aren’t infinitely patient. Sluggish infrastructure performance can make shoppers wait precious seconds longer than they can stand, sending them fleeing to other sites for a faster purchase. Our federal government’s halting rollout of the Health Insurance Marketplace website is a glaring example of what can happen when IT infrastructure isn’t solid. A few bad user experiences that go viral can be damaging enough. Tens of thousands can be crippling.
High Availability (HA) systems traditionally have been confined to large datacenters because of their high cost and the difficulty of scaling down clustered servers and shared storage arrays to support smaller environments such as Small Office Home Office (SOHO) and Remote Business Office (ROBO).
Microsoft and LSI are changing that.
As part of Windows Server® 2012, Microsoft and LSI collaborated on the development of the innovation called Cluster in a Box (CiB). With CiB, HA systems are now available for SOHO and ROBO applications.
Try using a sledgehammer to pack 15 pounds of potatoes into a bag with a 5-pound capacity, and what do you end up with? Too much messy and disgusting material crammed into a vessel too small for the job and a lot of sloppy overspill.
Unless you have the right sledgehammer. What does this have to do with computer storage? Plenty. And it all starts with a new data-reshaping capability of LSI® DuraWrite™ technology. Keep the numbers in mind: 15 pounds of data in a 5-pound bag.
Many of you may have heard of a poem written by Robert Fulgham 25 years ago called “All I Really Need to Know I Learned in Kindergarten.” In it he provides such pearls of wisdom like “Play fair,” “Clean up your own mess,” “Don’t take things that aren’t yours” and “Flush.” By now you’re wondering what any of this has to do with storage technology. Well the #1 item on the kindergarten knowledge list is “Share Everything.” And from my perspective that includes DAS (direct-attached storage).
Scaling compute power and storage in space-constrained datacenters is one of the top IT challenges of our time. With datacenters worldwide pressed to maximize both within the same floor space, the central challenge is increasing density.
At IBM we continue to design products that help businesses meet their most pressing IT requirements, whether it’s optimizing data analytics, data management, the fastest growing workloads such as social media and cloud delivery or, of course, increasing compute and storage density. Our technology partners are a crucial part of our work, and this week at AIS we are teaming with LSI to showcase our new high-density NeXtScale computing platform and x3650 M4 HD server.
Each new generation of NAND flash memory reduces the fabrication geometry – the dimension of the smallest part of an integrated circuit used to build up the components inside the chip. That means there are fewer electrons storing the data, leading to increased errors and a shorter life for the flash memory. No need to worry. Today’s flash memory depends upon the intelligence and capabilities of the solid state drive (SSD) controller to help keep errors in check and get the longest life possible from flash memory, making it usable in compute environments like laptop computers and enterprise datacenters.
