Product Description
The HP 804370-001 is a high-performance Smart Array P204i-b RAID controller designed to provide advanced storage connectivity and data protection for HP ProLiant Gen9 servers. This controller supports the latest SAS 12Gb/s interface, offering significantly faster data transfer rates compared to previous generations, along with SATA/600 compatibility for broader drive support. Its PCIe 3.0 x8 host bus ensures ample bandwidth for demanding storage operations. Equipped with 1GB of Flash-backed Write Cache (FBWC), the P204i-b controller 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 comprehensive range of RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60, providing flexibility for various performance, redundancy, and capacity requirements. Designed as a plug-in module, the 804370-001 integrates seamlessly into compatible HP ProLiant server platforms, such as the DL360 Gen9 and DL380 Gen9. It allows for the management of up to eight internal SAS or SATA drives, making it suitable for building robust and scalable storage solutions within the server. Features like HPE SSD Smart Path further enhance performance, particularly for Solid State Drives.
