631680-B21 HP 1GB FBWC Module for Smart Array
Enterprise-grade 1GB Flash-Backed Write Cache (FBWC) memory module, engineered to optimize transactional write performance and safeguard cached data on HPE Smart Array P-Series controllers.
The 631680-B21 is an internal modular Flash-Backed Write Cache (FBWC) memory upgrade engineered specifically for HPE Smart Array P-Series storage controllers. Providing a 1GB cache storage capacity, this module significantly accelerates data write operations by temporarily storing transactional logs in high-speed cache memory before writing to disk array volumes. Outfitted with advanced flash-memory storage logic, it interfaces directly with a separate capacitor or battery backup pack; in the event of a sudden data center power loss, the processing logic immediately mirrors volatile data into non-volatile flash storage to ensure zero data loss.
