HPE 660093-001 FBWC Capacitor Pack with 36-inch Cable
Overview
The HPE 660093-001 is a capacitor pack specifically engineered for HPE Smart Array controllers in select ProLiant Gen8 server environments. Its critical function is to protect in-flight data residing in the controller's Flash-Backed Write Cache (FBWC) during an unexpected power loss. This component is essential for maintaining data integrity in enterprise storage configurations, providing the temporary power needed to write cached data to non-volatile flash memory, thereby preventing data loss that would otherwise occur. This unit replaces traditional battery-backed systems with a more reliable super-capacitor solution. The primary technical advantage is the elimination of battery life limitations and the lengthy recharge times associated with them. The capacitor pack provides up to 80 seconds of power, which is more than sufficient for the FBWC module to secure its data. This design enhances long-term reliability and reduces the maintenance overhead associated with battery monitoring and replacement cycles. Designed for seamless integration, this capacitor pack connects directly to the Smart Array controller within the server chassis. Its 36-inch (914 mm) cable provides flexible routing options for various ProLiant server models, including DL, ML, and SL series. The health and status of the capacitor are monitored through the server's integrated management suite, ensuring administrators are alerted to any potential issues and can maintain a robust, resilient storage infrastructure.
