The RS2VB0x0 controllers ship with a SuperCap module which acts as a battery backup unit with the capability to keep functional during the life cycle of the RAID controller. The SuperCap utilizes capacitors to maintain a voltage charge. In the event of a power outage, the SuperCap powers the Raid controller Flash Back Up unit long enough to copy the cache memory contents to NV flash memory for long term storage.
The Flash Back Up unit and SuperCap are connected with the iBBU power cable (included) connected between the white connectors on the two devices.
The SuperCap contains monitoring circuitry that reports status to the Intel® RAID Web Console 2 utility.
Warranty period for the SuperCap and Flash Backup Unit is three years.
