Product Description
The HP 804399-B21 Smart Array controller represents a significant advancement in storage connectivity for HP ProLiant servers, offering a 12Gb/s SAS interface that maximizes performance for modern storage devices. This controller is built on the PCIe Gen3 x8 standard, ensuring ample bandwidth to support high-speed data transfers, which is crucial for demanding applications and large datasets. It provides broad compatibility with both SATA and SAS drives, including traditional hard disk drives (HDDs) and solid-state drives (SSDs), allowing for flexible storage configurations tailored to specific needs. This controller boasts an extensive range of RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60. This comprehensive support enables administrators to implement sophisticated storage solutions that balance performance, data redundancy, and capacity. The inclusion of 2GB of Flash-Backed Write Cache (FBWC) is a vital feature for enterprise environments. FBWC protects cached data from loss during power interruptions or system crashes by using flash memory and a capacitor, thereby improving write performance and ensuring data integrity. Designed for HP ProLiant Gen9 and subsequent server generations, the 804399-B21 can directly manage up to 24 drives. For larger storage arrays, it supports expansion through SAS expanders, allowing for scalability to accommodate growing data requirements. Management is streamlined through HP's integrated server management tools, such as the Intelligent Provisioning and the Smart Storage Administrator (SSA), providing a unified interface for configuration, monitoring, and maintenance of the storage subsystem.
