Optical Drive; Tape Drive; Table 16. Hard-Drive Backplane Options - Dell PowerEdge R620 Technical Manual

Table 16 lists the R620 backplane options for supported Dell PERC cards.
Backplane options
1
4 x 2.5"
1
8 x 2.5"
2
10 x 2.5"
3
4 x 2.5" + 2 PCIe SSDs
1
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.
3
Express Flash PCIe SSD configurations support only the mini-type PERC.
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.

Optical drive

The R620 supports one ultra-slim, 9.5mm, 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 drive is an option for the
10-drive bay chassis. The R620 supports DVD-ROM and DVD+/-RW. An optical drive cable is
included.

Tape drive

The R620 supports an external tape drive only through the SAS 6Gbps HBA. The R620 does not
support internal tape drives.
