Product Description
The HP 749796-001, identified as the Smart Array P440ar, is a high-performance RAID controller designed for advanced storage solutions within HP ProLiant servers. It supports a 12Gb/s SAS and SATA/600 interface, delivering exceptional throughput for demanding enterprise workloads. The controller is equipped with 2GB of cache memory, which significantly accelerates data operations by buffering frequently accessed data, thereby reducing latency and improving overall system performance. This makes it ideal for applications such as databases, virtualization, and large-scale data processing. This Smart Array controller offers a comprehensive range of RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60. This extensive support allows for highly flexible storage configurations, enabling administrators to implement sophisticated data protection strategies, optimize performance, and manage storage capacity efficiently. The P440ar is often found in a RAID-on-Chip (RoC) or mezzanine form factor, integrating directly into the server's motherboard or a dedicated slot for a compact and efficient solution. Further enhancing its enterprise capabilities, the P440ar controller supports optional features like Flash-Backed Write Cache (FBWC), which provides data protection for the cache memory in the event of a power loss. This ensures data integrity and reduces the risk of data loss during unexpected shutdowns. The 749796-001 is a robust and reliable component for building high-availability and high-performance storage infrastructures within the HP ecosystem.
