Product Description
The HP Smart Array P212 controller is a cost-effective RAID solution designed for HP ProLiant servers, providing essential data protection and performance capabilities for direct-attached storage. This specific configuration, 462828-B21-HIGH, includes 256MB of cache memory, which aids in accelerating RAID operations. Unlike controllers with larger cache modules, the P212 can also operate in HBA (Host Bus Adapter) mode, allowing drives to be presented directly to the operating system for software RAID or other management solutions. It features two ports that support both SAS (Serial Attached SCSI) and SATA (Serial ATA) drives, offering flexibility in drive selection. The controller utilizes a PCI Express 2.0 x8 interface, ensuring adequate bandwidth for data transfer between the drives and the server's main memory. The P212 primarily supports RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), and RAID 10 (striped mirrors for performance and redundancy), making it suitable for applications that require a good balance of speed and data protection. This controller is designed for environments where basic RAID functionality is needed without the complexity or cost of higher-end solutions. Its compatibility with HP ProLiant servers and support for common RAID levels make it a reliable choice for general-purpose storage and entry-level enterprise applications. The ability to function as an HBA adds to its versatility for various server configurations.
