Intel RAID Maintenance Free Backup Unit AXXRMFBU2

The Intel® RAID Maintenance Free Backup Unit(RMFBU) AXXRMFBU2 is an optional accessory for selected RAID modules.

The RMFBU protects the integrity of the cached data on Intel® Integrated RAID Modules by offloading data stored in the RAM cache to the NAND flash if there is a complete AC power failure or a brief power outage.

The RMFBU provides an alternative to use an uninterruptible power supply (UPS) or it can act as a second level of fault tolerance when used with a UPS. Furthermore, it eliminates the need for lithium ion (Li-ion) batteries traditionally used to protect DRAM cache memory on PCI RAID controllers.
