CacheCade
CacheCade is a technology that provides automated storage tiering on SSDs with the PERC H810
and H710. 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 T620 8-drive and 16-drive bay chassis, without the Express Flash PCIe SSDs, support up to three
media bays through one of the following options:

Up to two SATA half-height DVD-ROM or DVD R/W drives, plus one SAS tape drive

Up to one SATA half-height DVD-ROM or DVD R/W drives, plus one internal Dell PowerVault™
RD1000 drive and one SAS tape drive
With the Express Flash PCIe SSDs, the T620 8-drive and 16-drive bay chassis can support one optical
drive, one RD1000, or one SAS tape drive.
The T620 12-drive bay supports one media bay through one of the following options:

Up to one SATA half-height DVD-ROM or DVD R/W drive

Up to one internal PowerVault RD1000 drive

Up to one SAS interface tape drive
