Product Description
The IBM 85F7214 Raid Controller Cache Card is an essential add-on for compatible IBM RAID controllers, significantly improving both performance and data safety. Its primary function is to provide a battery-backed write cache (BBWC), which acts as a high-speed buffer for write operations. This buffer allows the RAID controller to acknowledge write commands more quickly, thereby boosting the overall write performance of the storage subsystem. Crucially, the battery backup feature ensures that any data residing in the cache is preserved in the event of an unexpected power loss or system interruption. The battery maintains power to the cache memory until system power is restored, preventing data corruption or loss that could otherwise occur. This feature is vital for maintaining data integrity in mission-critical environments where data loss is unacceptable. The 85F7214 is designed to integrate seamlessly with specific IBM RAID controller models, offering a reliable and efficient way to enhance existing storage solutions. By offloading write operations to the faster cache and protecting them with battery backup, this card contributes to improved application responsiveness and greater data resilience.
