Battery-backed write cache module HP BBWC 128MB Cache Enabler (MPN 453833-001-RFB)

HP BBWC 128MB Cache Enabler (MPN 453833-001-RFB) is a battery-backed write cache module designed for compatible HP server storage controllers. The module provides 128 MB of protected cache memory to buffer pending write operations. In the event of power loss, the integrated battery maintains the cache contents long enough for the system to complete or preserve writes, reducing the risk of data loss and improving write I/O responsiveness in supported server configurations.

Advantages

The HP BBWC 128MB Cache Enabler increases write performance by enabling write-back caching on supported controllers while offering data protection via its battery-backed memory. The 128 MB capacity provides a dedicated area for pending writes, improving throughput for write-heavy workloads. Because the module is designed for HP server environments and uses the manufacturer part number 453833-001-RFB, compatibility and traceability are simplified when matching to supported RAID controllers and server models.

Suitable for

• Servers that need improved write performance with controlled risk of data loss
• Environments running write-intensive database or logging workloads where write-back caching is supported
• IT administrators replacing or upgrading HP storage controller cache modules
