RAID, CONTROLLER PCIE 8 PORT, LSI 9271-8I, LOCKED

GE Raid Controller PCIe 8 Port LSI 9271-8i, Locked Part #8770000-125

RAID caching is a cost-effective way to improve I/O performance by writing data to a controllers’ cache before it is written to disk. In write-back mode, data written to cache is vulnerable until it is made permanent on disk. To avoid the possibility of data loss or corruption during a power or server failure, Avago offers the Cache Vault flash cache protection module or the LSIiBBU09 battery backup unit for the Mega RAID SAS 9271-8i controller. Cache Vault flash cache protection uses NAND flash memory powered by a super-capacitor to help protect data stored in the Mega RAID controller cache. The RAID controller automatically writes the data in cache memory to flash storage when a power failure occurs, while the super-capacitor keeps the current going during the process. When the power comes back, the DRAM is recovered from flash storage, and the system goes on without loss of data. Customers have the flexibility to choose a traditional Lion battery solution or a greener, lower total cost of ownership (TCO) cache protection solution with Mega RAID Cache Vault technology.
