Mini-type and adapter-type PERC available; adapter-type is available with the two-PCIe slot chassis and required when
configuring internal GPU or 3/4 length PCIe card
2
10-drive bay chassis supports only the mini-type PERC

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.
