Internal RAID Controllers
Dell PowerEdge R910 Internal RAID Controllers
The Dell PowerEdge R910 server supports two controllers designed for internal RAID configurations.
PERC H200: Dell introduced the H200 RAID controller to support the new SAS 6Gb/s hard drives as well as individual (logical) hard drives over 2TB. The H200 provides RAID 0, 1 and 10 functionality as well as support for solid-state drives (SSD) and internal tape drives. The H200 uses mini-SAS cables to connect to the backplane.
PERC H700: In addition to RAID 0, 1 and 10, the H700 controller adds support for RAID 5, 6, 50 and 60 configurations. 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.
