LSI has introduced an innovative new technology, the MegaRAID CacheVault. The technology provides flash memory-based cache protection for the company’s MegaRAID 6Gb/s SATA+SAS RAID controller cards. The technology works by using solid-state NAND flash memory to store data being held in the RAID controller card’s cache when power outages occur. What this means for IT departments is that battery backup units are no longer necessary.

The technology works by using solid-state NAND flash memory to store data being held in the RAID controller card’s cache when power outages occur. What this means for IT departments is that battery backup units are no longer necessary.
The CacheVault technology uses a super capacitor to keep the electrical current running while the controller cards’ cache is being written to the NAND solid-state memory. Once power is restored, the cache is restored from the solid-state memory.
