Cache protection module Broadcom CVM02
The Broadcom CVM02 Cache Protection Module (MPN 05-25444-00, EAN 830343003082) is an accessory designed for Broadcom 9460 and 9480 Series RAID controllers. It protects cached data from loss or corruption in the event of power interruptions by providing non-volatile flash cache storage and power-hold functionality, ensuring cached writes are preserved until safely written to storage media.
CacheVault technology used in the CVM02 secures cached data by powering critical controller components long enough to transfer volatile cache contents to NAND flash. Using a super-capacitor instead of Lithium‑ion batteries reduces maintenance needs and environmental impact while lowering total cost of ownership. The module maintains RAID performance and enhances system reliability in environments with demanding I/O workloads.
Install the CVM02 module into the supported RAID controller slot following the controller manufacturer’s installation procedure. Once installed and recognized by the controller firmware, the module will automatically protect volatile cache contents during power interruptions by transferring them to non‑volatile flash storage and restoring them when power is restored. Ensure firmware and controller drivers are up to date for full compatibility.
Use the CVM02 with Broadcom 9460/9480 Series controllers in systems with stable power and proper cooling. Regularly verify controller firmware compatibility and monitor controller logs to confirm successful cache protection events.
