RAID Controllers & Batteries
Dell PowerEdge T310 RAID Controllers & Batteries
The Dell PowerEdge T310 server has several controller options available for internal and external 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. There is also the stripped down SAS 6/iR variant which offers only RAID 0 and 1 and no battery backup.
PERC 6/E: The PERC 6/E is for connecting legacy external enclosure arrays such as the PowerVault MD1000 or MD1120 directly to the host server. The controller provides onboard RAID options for the attached enclosure.
PERC H200: Dell also introduced the H200 RAID controller to support the new 6Gb/s hard drives as well as solid state (SSD) drives. The H200 provides RAID 0, RAID 1, and RAID 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.
