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.

The R520 supports one slim, 12.7mm, internal optical drive on the system board embedded SATA.

The R520 supports DVD-ROM and DVD+/-RW.

The R520 does not support internal tape drives.
