Dell provides highly capable RAID options for you to ensure that your data remains safe. Dell’s RAID
controller options offer impressive performance improvements, including the following features:
FastPath™ I/O: This feature can help accelerate performance when operating on SSDs.
Split mirror: This function allows you to break mirrored disk connection in order to quickly
replace a drive.
Physical disk power management (Dimmer Switch™): This feature allows for power control of
spare or idle drives, which can save energy and operating expenses.
The newest line of PERC (PowerEdge RAID Controller) cards offers high I/O performance for
database applications and streaming digital media environments. The T620 supports the new
PERC 8 family of controllers, adapter form factor only, with improved functionality and faster
performance. The internal RAID controllers have a dedicated connection to the system board.
The T620 also supports the new software RAID solution that supports RAID 0, 1, 5,
and 10. The T620 supports the PERC cards listed in Table 14.
