Also note an added special feature of these MegaRAID® SAS 9271-8i cards.
These cards support RAID caching.
What is this RAID caching?...well
RAID caching is a cost-eff ective 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 off ers the CacheVault fl ash cache protection module or the LSIiBBU09 battery backup unit for the MegaRAID SAS 9271-8i controller.
CacheVault fl ash cache protection uses NAND fl ash memory powered by a super-capacitor to help protect data stored in the MegaRAID controller cache. The RAID controller automatically writes the data in cache memory to fl ash 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 fl exibility to choose a traditional LiON battery solution or a greener, lower total cost of ownership (TCO) cache protection solution with MegaRAID CacheVault technology.
