CacheCade
CacheCade is a technology that provides automated storage tiering on SSDs with the PERC H810
and H710P. It works by detecting the most-often accessed data and copying it over time to the
CacheCade SSD(s) where that cached data is accessed directly, instead of accessing the hard disk
drives. This can dramatically increase how your applications respond when they are under peak
traffic times and how they perform when response time is critical.
CacheCade provides cost-effective performance scaling for database-type applications that
perform lots of random reads, and saves the cost of adding extra drives.
