LSI Logic CacheVault Accessory for 9460 9480 Series - Reliable Cache

In this review the LSI Logic 05-50039-00 CacheVault accessory is assessed as a targeted add-on for administrators running the LSI 9460/9480 Series RAID controllers. The bottom line is straightforward: this is a purpose-built module that provides non-volatile protection for controller cache to guard against data loss during power events. For anyone maintaining servers or storage arrays that use the 9460 or 9480 controllers, the CacheVault accessory is the single most direct way to preserve write caching behavior without risking corruption when power is interrupted.

Key Features

• Compatibility: Designed specifically for use with the LSI 9460 and 9480 Series RAID controllers to ensure reliable integration without adapter changes.
• Cache protection: Keeps controller cache contents safe during unexpected power loss so pending writes are preserved until power is restored.
• Easy installation: Attaches directly to supported RAID controllers which simplifies field replacement and reduces maintenance time.
• Server uptime focus: Helps maintain data integrity and recoverability, minimizing the risk of array rebuilds or data loss after outages.
• OEM accessory: As an accessory from the controller vendor it follows the intended design for those RAID models, reducing compatibility surprises.

Who It's For

This accessory is aimed at system administrators, data center technicians, and IT staff who operate servers with LSI 9460/9480 Series RAID controllers and need dependable cache persistence. It is most relevant where write caching is enabled and data integrity during power faults is a priority, such as virtualized hosts, database servers, and storage arrays.

It is not a standalone product for general consumers; buyers who do not already own a compatible controller or who require universal cache backup for a variety of controllers should look for broader solutions. Likewise, environments with battery-backed controller modules already in place may not need this accessory.

Pros & Cons

Pros

• Provides direct cache protection for the intended RAID controllers, reducing risk of data corruption after outages.
• Vendor-designed accessory ensures straightforward physical and firmware compatibility with 9460/9480 Series cards.
• Compact accessory that installs without major changes to server hardware, easing replacement during maintenance windows.

Cons

• Limited to the LSI 9460 and 9480 Series controllers, so it is not a universal solution for other RAID models or brands.
• As an accessory, it does not provide additional controller features beyond cache protection and depends on existing controller capabilities.
