Description
The Compellent K6H89-CML is a high-end RAID controller card built for demanding enterprise storage environments. Utilizing the high bandwidth of the PCI-Express interface, this card is capable of delivering exceptional performance for storage arrays, supporting multiple drives and complex RAID configurations. A key feature of this controller is its 512MB of onboard cache memory. This cache significantly accelerates read and write operations by temporarily storing frequently accessed data. Crucially, the integrated Battery Backup Unit (BBU) protects the data in the cache during unexpected power outages. The BBU ensures that any data residing in the cache is written to non-volatile storage before power is lost, preventing data corruption and loss. This controller is designed to provide robust data protection and high availability for critical applications. Its advanced RAID capabilities, combined with the cache and BBU, make it suitable for use in servers hosting databases, virtual machines, and other I/O-intensive workloads where data integrity and performance are paramount. The Compellent K6H89-CML represents a significant upgrade for storage subsystems requiring enterprise-grade reliability and speed.
