Additional Notes
Product Description
The Dell 70K80 is the cache backup battery used on PERC H710, H710P and H810 RAID controllers, found in many PowerEdge 12th-generation servers such as the R620 and R720. When the battery fails, the controller usually reports a battery fault and switches to write-through mode, which slows disk performance. Replacing it lets the controller return to write-back caching with protection for cached data during a power cut. NJ Bravo supplies this battery to IT dealers and corporate clients in Malaysia.
