Technical rules for PCIe slots

PCIe adapters must be installed in a specific order in your server.

Note

  • Performance may degrade when a x16 PCIe adapter is installed in a x8 PCIe slot.

    • When a ThinkSystem Intel E810-DA2 Ethernet Adapter is installed, the following adapters are not supported:
      • ThinkSystem RAID 9350-16i 4GB Flash PCIe 12Gb Adapter
      • ThinkSystem RAID 9350-8i 2GB Flash PCIe 12Gb Adapter
      • ThinkSystem RAID 5350-8i PCIe 12Gb Adapter
      • ThinkSystem 4350-8i SAS/SATA 12Gb HBA
      • ThinkSystem RAID 9350-16i 4GB Flash PCIe 12Gb Internal Adapter
      • ThinkSystem RAID 9350-8i 2GB Flash PCIe 12Gb Internal Adapter
      • ThinkSystem RAID 5350-8i PCIe 12Gb Internal Adapter

Install PCIe adapters in the following sequence:

  1. GPU adapters: Slot 2

  2. PCIe adapter for M.2 boot adapter: Slot 1, then slot 2

  3. RAID/HBA adapters: Slot 2, then slot 1

  4. Ethernet adapters: Slot 1, then slot 2
