HP 011786-001 is a 128MB battery-backed write cache (BBWC) memory module designed for HP Smart Array 641 and 642 RAID controllers. This enabler memory module enhances controller performance by providing persistent cache protection during power loss events, allowing write operations to complete safely even in unexpected shutdown scenarios. Compatible with select HP ProLiant servers running Smart Array 641/642 controllers, the module requires installation into the controller's dedicated memory slot and includes onboard battery backup circuitry. Typical applications include high-I/O database servers, virtualization hosts, and storage-intensive workloads where write-cache reliability is critical.
