Product Description
The Compaq 006174-001 Battery Cache Module is a critical component for maintaining data integrity in servers equipped with the specified Compaq or HP RAID controller (part number 194754-001). In the event of an unexpected power failure, the RAID controller's write cache can lose its data, potentially leading to data corruption or loss for the RAID array. This battery module acts as a temporary power source. When a power outage occurs, the Battery Cache Module instantly supplies power to the RAID controller's cache memory. This allows the controller sufficient time to write any data that was held in the volatile cache to its non-volatile memory or directly to the disk drives before power is completely lost. This process is essential for ensuring that all committed write operations are safely stored, thereby protecting the integrity of the RAID array. This module is typically rechargeable and designed to be hot-swappable, allowing for replacement or installation without requiring the server to be powered down. Its primary function is to enhance the reliability and data protection capabilities of the RAID subsystem, providing a crucial layer of defense against data loss due to power interruptions.
