There is more news on the SSD front as SearchStorage reports that EMC will introduce another direct-attached memory solution by placing SSD drives within their Clariion arrays. This is similar to the announcement earlier this year that they would make SSD drives available in their high-end Symmetrix arrays. Back then we wrote a series of blog posts about that announcement including:

Just about every major vendor has announced some type of solution to add more memory to their systems. This is an inevitable result of growing application needs and the demand for greater performance. Sun, NetApp and others have all made noise about incorporating more memory into their server and storage systems.
Recently we added another video to our blog on Caching as a Network Service to showcase some of the deployment differences of a number of these solutions.
The great news is that more options for deploying memory in the data center are becoming available, and the component choices only assist in helping customers design effective solutions.
However, the wave of memory-based solutions goes far beyond the introduction of another type of SSD component. It is important that editors and analysts covering this new category of solutions keep an architectural perspective about how memory is being deployed, compared to the just looking at the component view.
The tricky part is that SSDs have been around for over 30 years. Since then there have been a whole wave of new memory-based solutions (many which make use of SSDs) that can reside within servers, within the network, or within the subsystem. In each of these areas, the deployment model be quite different. Sometimes memory will be deployed as a persistent media, often it will be deployed to assist and complement a persistent disk-based infrastructure.
Whichever the case, it is critical that we graduate from component-level coverage to system-level coverage.Our series on Memory in the Data Center is a great resource to get started.
