HPE P47781-B21 MR416i-o Gen11 Storage Controller
Overview
The HPE MR416i-o Gen11 SPDM Storage Controller, model P47781-B21, is designed to expand direct-attached storage capabilities within HPE ProLiant servers. This controller acts as a critical interface for connecting and managing multiple storage devices, enabling higher density and performance for data-intensive applications. It is specifically engineered for environments requiring robust storage expansion without the complexity of external storage arrays, fitting seamlessly into server rack infrastructure.
Compatibility
This controller is compatible with HPE ProLiant Gen11 servers. It is designed to integrate with specific HPE server chassis configurations that support SPDM (Server Peripheral Device Management) and require additional internal storage connectivity. Refer to HPE's official documentation for exact server model compatibility, as it is tailored for specific server platforms within the Gen11 generation.
Installation Notes
Installation requires direct internal mounting within a compatible HPE ProLiant Gen11 server chassis. Ensure proper seating in the designated PCIe slot or backplane connector. Connection to storage devices is typically via SAS cables (not included). Consult the HPE ProLiant Gen11 server maintenance and service guide for detailed installation procedures, torque specifications, and required tools. Proper airflow and thermal management within the server chassis are critical for controller longevity.
