Best PCIe Slots Configuration for HPE DL380 Gen10 2026

The HPE ProLiant DL380 Gen10 server excels with flexible PCIe slots for 2026 data centers. This guide details optimal configurations for GPUs, NICs, and storage controllers to maximize performance.

With Gen10's riser options, achieve up to 8 PCIe Gen3 slots. Follow steps for best bandwidth and cooling.

Step 1: Identify PCIe Slot Specs

DL380 Gen10 offers slots 1-8 across risers. Primary riser: x16/x8/x8. Secondary: x16/x8.

  • Slot 1: x16 full-height
  • Verify PSU compatibility

Step 2: Optimal Slot Allocation

1. Install GPUs in slots 1/3 for max bandwidth. 2. NICs in x8 slots. 3. HBAs last.

  • Avoid adjacency for airflow
  • Use PCIe switches if needed

Step 3: Configuration for AI/ML Workloads

For 2026 AI, pair NVIDIA A100 in x16 slots with NVLink bridges.

  • Firmware update first
  • iLO monitoring

Step 4: Troubleshooting Common Issues

Check riser cables, BIOS PCIe settings, and power draw limits.

  • Reset to defaults
  • HPE SSA diagnostics
