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 powerfailure 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.
Suitable for file, web, database, and email servers, storage appliances, high-performance computing, digital content, medical imaging, and similar applications
Overview
RAID controller cards temporarily cache data from the host system until it is successfully written to the storage media. While cached, data can be lost if system power fails, jeopardizing the data's permanent integrity.
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® flash cache protection modules and battery backup units (BBUs) protect the integrity of cached data by storing cached data in non-volatile flash cache storage or by providing battery power to the controller.
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. 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 provide more environmentally friendly cache protection, all while maintaining optimal RAID performance.
Lower total cost of ownership (TCO) with CacheVault technology by reducing hardware maintenance and disposal issues associated with lithium-ion batteries
Battery backup units allow for higher ambient temperatures
