Product Description
The HP 726793-B21-RFB is a high-performance RAID controller, specifically the Smart Array P731m model, designed to provide advanced storage management and data protection for HP ProLiant servers. This controller utilizes a PCI Express 3.0 x8 interface, ensuring high bandwidth connectivity to the server's motherboard for rapid data transfer. It is equipped with four internal SATA/SAS ports, capable of supporting both Serial ATA and Serial Attached SCSI drives operating at 6Gb/s, offering flexibility in storage configurations. A key feature of the P731m is its 2GB Flash-Backed Write Cache (FBWC). This cache memory significantly accelerates write operations by temporarily storing data before it is written to the drives. The 'Flash-Backed' aspect means that the data in the cache is protected against power loss by a flash memory module, ensuring data integrity even in the event of an unexpected shutdown. This greatly improves performance for write-intensive workloads and enhances data reliability. The Smart Array P731m supports a comprehensive range of RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60. This allows administrators to configure storage arrays that balance performance, capacity, and redundancy according to their specific needs. Whether it's maximizing read/write speeds with RAID 0 or ensuring high data availability with RAID 6 or RAID 10, this controller provides the tools to build robust and efficient storage solutions within HP server environments. The 'RFB' designation typically indicates a Refurbished product.
