Internal RAID Controllers
Dell PowerEdge R710 Internal RAID Controllers
The Dell PowerEdge R710 server supports several controllers designed for internal RAID configurations.
PERC 6/i: The PERC 6/i controller is a carryover from Dell's 9th & 10th generation servers and offers support for RAID levels 0, 1, 5, 6, 10, 50 & 60 with throughput of up to 3Gb/s. It also features battery-backed write cache (BBU) in the event of a power failure. In addition, there is a stripped down SAS 6/iR variant that offers simple RAID 0, 1 and non-RAID configurations but no battery backup.
PERC H200: Dell introduced the H200 RAID controller to support the new SAS 6Gb/s hard drives as well as solid state (SSD) drives. The H200 provides RAID 0, 1 and 10 functionality as well as support for internal tape drives. The H200 uses different mini-SAS cables to connect to the backplane.
PERC H700: The H700 controller supports both 6Gb/s hard drives and is backwards-compatible with 3Gb/s drives as well. The H700 also supports solid state (SSD) drives and is required for individual (logical) hard drives over 2TB. The PERC H700 controller features battery-backed write cache in the event of a power failure and supports self-encrypting drives (SED).
A rechargeable lithium-ion battery back-up (BBU) was provided with certain models to protect write cache in the event of a sudden power failure. These batteries are known to eventually lose their ability to hold a charge. When this happens, the battery must be replaced.
Unless otherwise noted, controllers have been tested and pulled from working servers and are backed by our 90-day parts replacement warranty.
