Will adding SSD’s help administrators eliminate storage IO bottlenecks?

Will adding SSD’s help administrators eliminate storage IO bottlenecks? The answer is probably yes if a true hybrid solution, with intelligent tiered management, is implemented but unlikely if the tiering management is a simple retread of traditional tiered management thinking.

So, it depends. First consider the data landscape the company has, which is highly dependent upon the applications in play. While SSD’s are a key element of performance tiering solutions it is the tiered management software that is critical element to an effective integration of SSD and HDD. When done correctly Hybrid solutions support mixed media vLUN’s that seamlessly, transparently and efficiently place data on the most effective media in a timely manner. This approach is especially effective for companies experiencing data access profiles that create what I call, performance starved applications.

Performance degraded applications that are caused by storage IO bottlenecks can include transaction heavy db applications, data mining, financial and business analytics, business decision systems, virtualization implementations etc. So in short, absolutely, SSD’s can provide a solution but with the caveat that it is the autonomic, intelligent tiered storage management software, not the physical media, that is the essence of a scalable, pragmatic, high performance solution.

It is the advanced tiered storage management tools that integrate the performance attributes of SSD or/and RAM and the capacity attributes of HDD. This managed integration of technologies delivers an interesting and effective blending of complementary storage attributes to address unique performance challenges.

Not all SSD solutions deliver equal performance, simply adding SSD into the storage hierarchy without the support of meaningful management software will not meet expectations.

"SEO" can refer to "search engine optimizers," a term adopted by an industry of consultants
who carry out optimization projects on behalf of clients, and by employees who perform SEO
services in-house. Search engine optimizers may offer SEO as a stand-alone service or as
a part of a broader marketing campaign. Because effective SEO may require changes to the
HTML source code of a site, SEO tactics may be incorporated into web site development and
design. The term "search engine friendly" may be used to describe web site designs, menus,
content management systems, images, videos, shopping carts, and other elements that have
been optimized for the purpose of search engine exposure.
