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 PowerEdge RAID Controllers (PERCs) offer high I/O performance for a variety of
uses, including database applications and streaming digital media environments.
The PERC S110 is supported on the R720 (3.5-inch chassis only) and is not supported on the
R720xd.
