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 offer high I/O performance for
database applications and streaming digital media environments. The internal RAID controllers have
a dedicated connection to the system board. The R520 supports the new PERC 8 family of
controllers with improved functionality and faster performance.
The default PERC for the R520 is a mini-type PERC. The R520 also supports the new software RAID
solution that supports RAID 0, 1, 5 and 10. The R520 supports the PERC cards listed in Table 12. For
more information about the latest PERC offerings, see Dell.com/PERC.
