Key points to note on these FBUO2 LSI / Broadcom MegaRAID CacheVault Modules:-
Data center managers and architects are expected to do more than ever, including protecting rapidly expanding volumes of data, meeting performance requirements of mission-critical applications, and implementing a variety of green, low-cost initiatives.
RAID caching is a cost-effective way to improve I/O performance by writing data to a controller’s cache before it is written to disk. However, in the event of a power or server failure, the writes in cache may be lost. CacheVault™ technology prevents data loss by powering critical components of the card long enough to automatically transfer the cached data to NAND flash.
Once power returns, the data is restored to the cache and normal operation resumes. Combining the Broadcom MegaRAID® 95xx and 94xx Tri-Mode and MegaRAID 93xx controllers with CacheVault technology provides the industry’s most reliable RAID solution.
By using a super capacitor instead of lithium-ion batteries, CacheVault technology virtually eliminates hardware maintenance costs associated with batteries, lowers total cost of ownership over the life of the controller card, and provides more environmentally friendly cache protection, all while maintaining optimal RAID performance.
Write-Back Cache Protection:
The CacheVault CVPM02 and CVPM05 energy backup modules protect the write-back cache function that hardware RAID controller users require. RAID caching is a cost-effective way to improve I/O performance by writing data to a controller’s cache before it is written to disk.
Write-back cache improves application performance by storing write data to highperformance cache memory during periods of heavy use. Where there is a break in user requests, the data is written from the cache memory to the array.
During normal write-back operation, data is written to cache (DRAM), the I/O is acknowledged as “complete” to the application that issued the write, and later the write is flushed to disk.
If power is lost while write-back cache is enabled, the writes in DRAM may be lost. Since the controller has already acknowledged the I/O as complete, the application is unaware of the data loss.
Key Features:
- :: Cached data protection for MegaRAID 95xx, 94xx, and 93xx series adapters.
- :: NAND flash protects the integrity of cached data in the event the system stops responding, crashes, or experiences kernel panics or power failures.
- :: Automatically transfers cached data to flash storage when a power failure occurs.
- :: Eliminates the need for lithium-ion batteries and associated hardware maintenance cost, resulting in a greener, lower total cost cache protection solution.
- :: Does not require special IATA shipping compliance (for international customers).
- :: Suitable for file, web, database, and email servers, storage appliances, high-performance computing, digital content, medical imaging, and similar applications.

Benefits of CacheVault Technology vs. BBUs:
Why its a win-win situation using these BBUs
Older generations of RAID controllers used lithium-ion-based battery backup units (BBUs) to keep the data resonate in the cache memory until power could be restored. Data was only available for up to 72 hours.
Over the life of a controller, the battery needed to be replaced numerous times, as it is only good for about 1 ½ years, which increased cost of ownership.
Again, unlike super-capacitors, batteries cannot sit on the shelf for a long period of time without requiring re-charging, making inventory management costly.
Furthermore, shipping and disposing of lithium-ion batteries require special considerations and fees.
