Hewlett Packard Enterprise 381513R-B21 RAID Controller

The Hewlett Packard Enterprise 381513R-B21 is an HP Smart Array P800 RAID controller that provides hardware-based RAID management for disk arrays, enabling administrators to configure and maintain redundant storage configurations independent of software RAID routines. Identified by the part number 381513R-B21, this card belongs to HP's Smart Array family and represents a specific implementation of the P800 line for managing multiple disks as a single logical storage unit. As a dedicated RAID controller, the P800 enables hardware-level management of disk arrays, contributing to data organization and reliability in storage environments where consistent performance and fault tolerance are critical. Because it offloads RAID processing from the host, it can help reduce CPU overhead and streamline storage administration. The 381513R-B21 variant is designed to fit into standard enterprise storage workflows and is synonymous with HP's tradition of Smart Array reliability and enterprise-grade RAID management.
