Product Description
The HP 749796-001-RFB is a Smart Array P440ar RAID controller, a high-performance storage solution designed for HP ProLiant servers. This controller provides advanced capabilities for managing storage arrays, offering both SAS 12Gb/s and SATA 6Gb/s connectivity through its two ports, which can be configured for internal or external drive connections. Its PCI Express 3.0 x8 interface ensures high bandwidth, allowing for rapid data transfer between the storage devices and the server's system resources. Key to its performance is the inclusion of 2GB of Flash-Backed Write Cache (FBWC). This cache accelerates write operations by temporarily storing data before it is committed to the drives. The 'flash-backed' nature means that the data in the cache is protected against power loss by flash memory, ensuring data integrity even in the event of an unexpected shutdown. This significantly improves the responsiveness of write-intensive applications. The P440ar controller supports a wide range of RAID levels, including RAID 0 for performance, RAID 1 for mirroring, RAID 5 and RAID 6 for parity-based redundancy, and RAID 10/50/60 for combined performance and protection. This flexibility allows administrators to configure storage solutions that meet specific requirements for data availability, fault tolerance, and speed, making it a versatile component for various server workloads.
