HPE P48803-B21 – DL380 Gen11 2U x16/x16/x16 Primary Riser Kit

Overview

The HPE P48803-B21 is a PCIe riser kit designed for HPE ProLiant DL380 Gen11 servers to expand internal PCIe connectivity. It provides additional PCIe Gen5 slots, enabling installation of network cards, storage controllers, or accelerator adapters.

This riser is part of the server’s internal expansion architecture and is used to increase I/O capability in enterprise compute environments. It supports high-bandwidth PCIe configurations for performance-critical workloads.

It is installed inside supported DL380 Gen11 chassis as part of the primary riser assembly. The kit replaces or extends the default riser configuration depending on server build.

It is commonly used in enterprise data centers where additional PCIe lanes are required for virtualization, storage scaling, or GPU/accelerator deployment.

Typical Deployment Scenarios

Used in HPE ProLiant DL380 Gen11 servers requiring expanded PCIe slot availability. Common in virtualization hosts, high-performance computing nodes, storage controller expansion, and network-intensive environments.
