Demartek Publishes Evaluation of LSI MegaRAID CacheCade Performance

1 November 2010

Interest in solid-state storage (SSS) is high, and IT professionals are beginning to explore various ways to take advantage of the increased performance and reduced power consumption that SSS offers. Various enterprise applications across the spectrum of size and complexity may be good candidates for SSS.

SSS can be deployed directly as primary storage where the users decide what data to place on the storage, or it can be deployed as a cache in front of traditional storage, where the storage controller determines what data is placed on the SSS or solid state disk (SSD). Each implementation has advantages.

LSI Corporation commissioned Demartek to evaluate MegaRAID CacheCade software in a web server environment. CacheCade software is optimized to enhance read cache performance with features such as hot spot detection and retention. As the operating system makes read requests to a CacheCade-managed volume, the logical block is written to the SSS and subsequent read requests for this cached data are serviced by the SSS. Hot spot detection and retention ensures that only frequently accessed data is placed into the SSD storage.

We achieved impressive results in the webserver environment using CacheCade software.
