P48803-B21 HPE DL380 Gen11 x16/x16/x16 Primary Riser Kit
The P48803-B21 is a dedicated primary riser card kit designed exclusively for the HPE ProLiant DL380 Gen11 2U rack server. It replaces the default primary riser to deliver three full-width PCIe 5.0 x16 expansion slots, enabling deployment of high-performance add-in cards such as GPUs, NVMe storage controllers, 100G/200G NICs, and advanced RAID/HBA adapters.
Built for enterprise-grade reliability and 24/7 data center operation, this riser unlocks the full PCIe 5.0 bandwidth potential of the DL380 Gen11 platform, supporting modern workloads including AI/ML inference, high-speed storage, virtualization, and software-defined networking.
This riser kit provides three PCIe 5.0 x16 slots with distinct form factor support to maximize flexibility:
- Slot 1: PCIe 5.0 x16, Full Height, Full Length (FHFL)
- Slot 2: PCIe 5.0 x16, Full Height, Full Length (FHFL)
- Slot 3: PCIe 5.0 x16, Full Height, Half Length (FHHL)
It is engineered to maintain signal integrity and thermal efficiency in the 2U chassis, supporting hot-plug functionality where enabled by the server and add-in cards. The kit includes the riser card and necessary mounting hardware for tool-less installation, replacing the default primary riser to enable full-width PCIe 5.0 expansion. It is required for configurations using the 24NVMe drive bundle, ensuring compatibility with high-density storage setups.
