Product Description
The HP Smart Array P400 Controller, identified by SKU 411064-B21, is a powerful storage solution designed to deliver high performance and reliability for HP ProLiant servers. It supports both SAS (Serial Attached SCSI) and SATA (Serial ATA) drives, offering flexibility in storage configurations. With its 256MB of cache memory, the P400 accelerates data access and processing, significantly improving the performance of demanding applications and workloads. This controller supports a comprehensive suite of RAID levels, including RAID 0 for striping without parity, RAID 1 for mirroring, RAID 5 for striping with distributed parity, RAID 6 for striping with dual distributed parity, and RAID 10 for a combination of mirroring and striping. This wide range of options allows administrators to tailor their storage architecture to meet specific requirements for performance, data redundancy, and fault tolerance. The PCIe 2.0 x8 interface provides ample bandwidth for high-speed data transfers between the controller and the server's system. Key functionalities of the Smart Array P400 include support for hot-plug drives, enabling drives to be added or removed without system interruption, and online RAID management features such as online capacity expansion and online RAID level migration. These capabilities are crucial for maintaining high availability and simplifying storage administration in dynamic server environments. The controller is designed for easy integration and management within the HP ecosystem.
