Product Description
The DEC D070002-02 Battery Module is a crucial component for any server utilizing a RAID controller with a write-back cache. In such configurations, data is initially written to a high-speed cache memory for faster performance. However, if power is lost before this data is committed to the physical drives, it can be lost permanently. This battery module acts as a safeguard, providing enough power to flush the contents of the cache to a non-volatile memory on the RAID controller itself. This ensures that even in the event of an unexpected power failure, server shutdown, or system crash, the data residing in the cache is preserved. The module is designed to integrate seamlessly with compatible DEC RAID controllers, typically connecting via a dedicated port. Its primary function is to maintain data integrity and prevent data loss, which is paramount for business-critical applications and sensitive data storage environments. By investing in the D070002-02 battery module, organizations can significantly enhance the reliability and resilience of their storage infrastructure. It is a cost-effective solution that protects against potential data corruption and downtime caused by power interruptions. Proper maintenance and periodic testing of the battery module are recommended to ensure its optimal performance when needed.
