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 R620 supports one ultra-slim,  9.5 mm, internal optical drive (4-, 6-, or 8-drive bay options) on 
the system board embedded SATA. The R620 10-drive bay chassis, however, does not support an 
internal  optical drive due to space limitation;  an external USB optical is an option for the 10-drive 
bay chassis. The R620 supports DVD-ROM  and DVD+/-RW.  An optical  drive cable is included. 
The R620 supports an external  tape drive only through the SAS 6Gbps HBA. The R620 does not 
support internal  tape drives.
