LSI CacheVault Module Accessory Kit for 6Gb/s MegaRAID 9266 Series

Our review of the LSI CacheVault Module Accessory Kit focuses on its role as a practical add-on for servers using the 6Gb/s MegaRAID SAS2 controller 9266 series. For administrators who need a reliable, flash-based backup solution for controller cache, this kit supplies the essential CacheVault Flash Module and Power Module parts that restore nonvolatile caching after power events. The review finds it is straightforward to install and particularly useful when paired with the 9266-4i or 9266-8i controllers, delivering the core benefit of protecting write-back cache without replacing the entire controller.

Key Features

• Compatibility: Designed specifically to work with the LSI 6Gb/s MegaRAID SAS2 controller 9266-4i and 9266-8i, ensuring correct integration with those controller families.
• Flash based backup: The CacheVault Flash Module provides nonvolatile backup of cache data, which helps preserve pending writes across unexpected power loss.
• Included power module: The CacheVault Power Module supplies the energy needed to flush cache to the flash module in a power event, avoiding data loss from volatile write-back caches.
• Remote mounting option: The kit includes a remote cable extender and a CVPM remote mounting clip for flexible placement inside rack chassis.
• Serviceable accessory: As an accessory kit it lets administrators replace or add CacheVault functionality without swapping the whole controller unit.

Who It's For

The kit is ideal for IT professionals, system builders, and datacenter technicians who already use LSI 9266-4i or 9266-8i MegaRAID controllers and require a proven method to protect volatile cache contents. It is especially relevant where write-back caching is enabled and data integrity during outages is a priority.

It is not a standalone RAID controller or a universal backup device; buyers using different controller series or who need onboard battery backup should look for other solutions. Those who do not use MegaRAID 9266 series controllers should confirm compatibility before purchasing.
