External RAID Controllers

Dell PowerEdge R910 External RAID Controllers

The Dell PowerEdge R910 server supports several controllers designed for connection to external hard drive enclosures and tape libraries.

PERC 5/E: The PERC 5/E is used for connecting a PowerVault MD1000 external storage array directly to the host server. The controller provides onboard RAID 0, 1, 5, 10 and 50 options for the attached enclosure.

PERC 6/E: The PERC 6/E can connect a PowerVault MD1000 or MD1120 storage array directly to the host server and adds support for RAID 6 and 60. The controller provides onboard RAID options for the attached enclosure.

PERC H800: The PERC H800 external host RAID controller is designed for expanding storage to the Dell PowerVault MD1200 and MD1220 6Gb/s SAS enclosures.

6Gbps SAS HBA: The 6Gbps SAS HBA controller does not provide onboard RAID, however, it connects the host server to more advanced external hard drive enclosures and tape libraries such as the PowerVault MD3200, MD3220, TL2000 and TL4000.

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.
