The Dell PowerEdge 2950 server has several controller options available for internal RAID configurations. Earlier generations featured a PERC 5/i controller offering RAID 0, 1, 5, 10 & 50. The PERC 6/i controller introduced integrated memory cache and RAID 6 & 60 options. There are also non-RAID controllers and controllers limited to RAID 0 or 1.
A rechargeable lithium-ion battery back-up (BBU) was provided with PERC 5/i and 6/i 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. Controllers and batteries are backed by our 90-day parts replacement warranty.
