Product Description
The HP 491193-B21 is a high-performance Smart Array RAID controller designed to manage storage devices within HP ProLiant servers. It utilizes a PCIe x8 interface, ensuring ample bandwidth for data transfer between the controller and the server's motherboard. This controller supports the SATA/600 interface, enabling it to connect with modern SATA hard drives and SSDs at speeds up to 6Gb/s. Equipped with 256MB of cache memory, this RAID controller accelerates storage operations by buffering data. It provides robust hardware RAID capabilities, supporting various RAID levels such as RAID 0, 1, 5, 6, 10, and 50. This allows for flexible configuration options to balance performance, redundancy, and capacity based on specific application needs. By implementing hardware RAID, the 491193-B21 offloads RAID processing from the server's CPU, leading to improved system performance and efficiency. It is a critical component for ensuring data integrity, providing fault tolerance against drive failures, and optimizing storage throughput for demanding enterprise workloads.
