MegaRAID CacheVault flash cache protection

Cache options: 512 MB with battery backup, 512 MB and 1GB flash cache protection.
MegaRAID CacheVault flash cache protection uses NAND flash memory powered by a supercapacitor to protect data stored in the controller cache. This module eliminates the need for a lithium-ion battery commonly used to protect DRAM cache memory on PCI RAID controllers. To avoid the possibility of data loss or corruption during a power or server failure, CacheVault technology transfers the contents of the DRAM cache to NAND flash (CacheVault flash module (CVFM)) using power from the CacheVault power module (CVPM). After the power is restored to the RAID controller, CacheVault technology transfers the contents of the NAND flash back to the DRAM, which will eventually be flushed to disk.
