2011 has been a year in which SSD storage built up a head of steam for takeoff in 2012. Or, as Zsolt Kerekes said on storagesearch.com, “The user mood is changing from ‘Can I afford to use SSDs?’ to a realization that ‘I can’t afford not to use SSDs’.” It’s seen major new and maturing products and technologies, big-time venture capital funding, and catch-up efforts by major storage vendors shoehorning fast SSD into array architectures designed for much slower disks. Here are some of the SSD highlights of the past year.

The End of High-End Disk Storage?SSD ISN’T JUST HOT, IT’S A CATEGORY KILLER By Gareth Taube, Vice President Marketing, Kaminario |
IDC’s recently published Worldwide Solid State Storage Quarterly Update confirms what we’ve seen and said for months: SSD is hot and poised for a takeoff. According to IDC, SSD shipments jumped a whopping 67 percent to 6.66 million in the third quarter of 2011 compared to 4 million in the third quarter of 2010. Revenue from SSD sales took a similar leap of 91.6 percent to approximately $1.29 billion from $673 million in the third quarter of last year.
IDC further divides the growth by enterprise, client, and commercial segments and finds 110 percent revenue growth to $522 million in SSD for enterprise data storage arrays and servers. Client SSD sales, which are mostly for PC’s and laptops, more than doubled from $354 million to $716 million. This is on top of 2010, which was already a record year for SSD growth, according to IDC. Only the commercial segment, which consists of medical equipment, factory automation, aerospace, and military systems, saw a decrease in SSD sales from $70.7 million to $59.7 million. In an article in ComputerWorld, IDC is quoted saying that SSD is just now reaching the mainstream.

Direct path read temp and direct path write tempBy Eyal Markovich |
In a previous posts, “db file sequential read,” “db file scattered read” wait events, and “Direct path Read,” I explained three common wait events that are associated with I/O Wait. In this post, I will describe two other common wait events that in many cases are caused by weak storage performance.

More Discussion about MLC Flash and the EnterpriseEETIMES COLUMNIST SAYS INNOVATION IS MAKING MLC VIABLE By Gareth Taube, Vice President Marketing, Kaminario |
If you are considering migrating to flash SSD storage, you need to understand that there are two types of flash SSD. There are single-layer cell (SLC) NAND flash chips and multiple-layer cell (MLC) NAND flash chips. Essentially, MLC is less expensive and offers more capacity than SLC though SLC is generically faster. A knock on MLC is that the chips wear out quicker than SLC chips because additional work is required by the controller accessing the additional capacity.

Get the Most I/O Performance from Your SAP Oracle ApplicationsNEW ACCELERATING SAP PERFORMANCE AND SCALABILITY WHITEPAPER AVAILABLE NOW By Gareth Taube, Vice President Marketing, Kaminario |
We frequently speak with organizations that are considering consolidating their database applications to improve system management and flexibility as well as reduce costs. One popular area where consolidation is a hot topic is ERP applications. In a recent post, we talked about how the Israel Electric Company improved their SAP transaction speed by up to 25 times by using the Kaminario K2 all solid-state SAN storage solution. What this company and others like it found is that even if you put a lot of computing horsepower into your servers and databases, your application performance can suffer if your storage system can’t keep up. And, simply adding more disks doesn’t solve the problem. Read the rest of this entry »
