Product Description
The HP 726793-B21-1, identified as the Smart Array P731m controller, represents a high-end storage solution for HP ProLiant server environments. This controller is designed to manage internal and external storage devices, offering robust performance and data protection capabilities. It features four ports that support both SATA and SAS drives, operating at the 6Gb/s interface speed, providing flexibility in drive selection and ensuring high throughput for demanding workloads. A key feature of the P731m is its 2GB Flash-Backed Write Cache (FBWC). This technology significantly accelerates write operations by temporarily storing data in fast flash memory before it is written to the drives. Crucially, the FBWC is protected by a dedicated battery or capacitor module, ensuring that data in the cache is not lost during unexpected power outages or server reboots, thereby enhancing data integrity and reliability. Utilizing a PCI Express 3.0 x8 interface, the controller offers a substantial bandwidth connection to the server's motherboard, minimizing potential bottlenecks. The Smart Array P731m supports a comprehensive range of RAID levels, including RAID 0, 1, 1+0, 5, 5+0, 6, and 6+0, allowing administrators to configure storage for optimal performance, redundancy, or a balance of both. This makes it an ideal choice for mission-critical applications, virtualization, databases, and large-scale data storage.
