HPE P51083-B21 – DL380 Gen11 PCIe Riser Kit

HPE P51083-B21 – DL380 Gen11 PCIe Riser Kit

Overview

HPE P51083-B21 is a PCIe riser kit designed for the HPE ProLiant DL380 Gen11 server platform. It is used to expand internal PCIe slot capacity and enable installation of additional expansion cards such as network adapters, storage controllers, and accelerator modules.

This riser assembly is part of the server’s internal expansion architecture and provides the physical and electrical routing required for PCIe Gen5 devices within a 2U chassis layout. It does not perform any processing itself and functions as an interface extension component.

It is deployed in enterprise and data center environments where flexible PCIe expansion is required for high-density compute, virtualization, and storage-heavy workloads.

Typical Deployment Scenarios

• Expansion of PCIe slots in DL380 Gen11 servers
• Installation of NICs, HBAs, and GPU cards
• Enterprise virtualization infrastructure
• Data center rack server upgrades
• High-density compute deployments
