Product Description
The HP 749796-002, identified as the Smart Array P440Ar, is a high-performance SAS RAID controller designed to enhance storage capabilities within HP ProLiant Gen9 servers, specifically the DL380 Gen9. This adapter card provides advanced data protection and performance optimization through its robust RAID capabilities. Equipped with 2GB of Flash-Backed Write Cache (FBWC), the P440Ar controller significantly accelerates write operations by temporarily storing data before it is written to the drives. This cache is protected by a battery or capacitor, ensuring data integrity even in the event of a power loss. The controller supports a wide array of RAID levels, including 0, 1, 5, 6, 10, 50, and 60, offering flexibility to configure storage arrays based on performance, redundancy, and capacity requirements. With its 12Gb/s SAS interface, the controller ensures high-speed data throughput, essential for demanding enterprise workloads such as virtualization, database management, and large-scale data processing. The inclusion of two internal SAS ports allows for direct connection to internal drive bays, facilitating the creation of complex and high-availability storage solutions within the server.
