CacheCade
CacheCade 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.
