Cache (RAID card memory) backup
Cache boosts storage performance by enabling more parallel operations, reducing latency of parity calculations, and completing transactions quicker. It allows for data to be stored locally rather than waiting for drives or system memory. However, it introduces risk in the event of power or server failure. Therefore, a cache backup solution is highly recommended.
The Intel® Smart Battery Backup Unit (BBU) offers excellent cache backup. The optional battery backup maintains the integrity of data in transit to drives in the event of a power interruption or system failure. The latest Intel® RAID Smart Batteries AXXRSBBU8 and AXXRSBBU9 offer a new longer life with up to five years of service life and a higher-temperature lithium polymer BBU. The LiON-based backup offers multiple modes of operation and retention times.

Maintenance Free Backup |
The Maintenance Free Backup Unit (MFBU) is built using NAND flash that can retain data for up to ten years. In addition, it provides near instant optimal RAID performance versus traditional Lithium Ion (LiON) battery backup units (BBUs) which are limited to just days of retention and can take up to 8 hours to charge. The longer lasting technology also comes with a standard three year warranty. | ||||||
