Lsi Logic Ac 05-25444-00 Lsicvm02 Cache Vault Kit for 9361 9380 Brown Box

Cache Vault technology provides RAID controller cache protection using NAND flash memory and a supercapacitor. In the event of a power or server failure¸ Cache Vault technology automatically transfers cached data from the DRAM cache to flash. Once power is restored¸ the data in the NAND flash is copied back into cache until it can be flushed to the disk drives. This technology eliminates the need for Lithium-ION battery backups that are traditionally used to protect cache memory on PCIe RAID controllers.
