Product Description

P51083-B21 HPE DL380 Gen11 x16/x16/x16 Secondary Riser Kit

Overview

P51083‑B21 is a secondary PCIe riser expansion kit designed exclusively for the HPE ProLiant DL380 Gen11 2U rack server. It adds three full‑bandwidth PCIe 5.0 x16 slots to extend high‑speed I/O capabilities for GPUs, high‑performance NICs, NVMe storage adapters, and other enterprise expansion cards. This kit is intended for deployments requiring dense, high‑performance PCIe expansion beyond the primary riser.

Core Features

Three PCIe 5.0 x16 Slots: Delivers full 32 GT/s per‑lane bandwidth for next‑generation expansion cards
Slot Configuration:
- Slot 4: PCIe 5.0 x16, Full‑Height, Full‑Length (FHFL)
- Slot 5: PCIe 5.0 x16, Full‑Height, Full‑Length (FHFL)
- Slot 6: PCIe 5.0 x16, Full‑Height, Half‑Length (FHHL)
Secondary Riser Position: Installed in the secondary riser bay, routed to the second CPU (CPU 2) — requires a second processor to be installed
Cable‑Dependent Slot Enablement:
- Slot 4 is disabled by default; requires the P56074‑B21 Secondary 3x16 Cable Kit to activate
- Without the cable kit, only Slots 5 and 6 are functional
Tool‑Less Installation: Designed for quick, hot‑swap compatible deployment in DL380 Gen11 chassis
Optimized Airflow: Engineered to maintain server cooling efficiency with high‑power add‑in cards

Compatibility

Server Platform: HPE ProLiant DL380 Gen11 2U Rack Server only
Processor Requirement: Dual CPU configuration mandatory (CPU 2 must be present)
Required Accessory: P56074‑B21 Secondary 3x16 Cable Kit (to enable Slot 4)
Primary Riser Pairing: Complements the primary riser (P48803‑B21) for a total of up to six PCIe 5.0 x16 slots

Key Deployment Notes

Second CPU Required: The secondary riser connects exclusively to CPU 2; a single‑CPU system cannot use this kit
Cable Kit for Full Functionality: To use all three slots, you must order the P56074‑B21 Secondary 3x16 Cable Kit separately
Use Cases: Ideal for GPU‑accelerated computing, high‑speed networking (100/200/400GbE), NVMe over Fabrics, and storage controller expansion
Cooling Consideration: High‑power GPUs in FHFL slots may require upgraded fan kits for optimal thermal performance
