It works by detecting the most-often accessed data and copying it over time to theCacheCade SSD(s) where that cached data is accessed directly, instead of accessing the hard diskdrives. This can dramatically increase how your applications respond when they are under peaktraffic times and how they perform when response time is critical.CacheCade provides cost-effective performance scaling for database-type applications thatperform lots of random reads, and saves the cost of adding extra drives.
