PCIe expansion node specifications

Table 1. PCIe expansion node specifications
SizePCIe expansion node
  • Height: 41.0 mm (1.7 inches)
  • Depth: 562.0 mm (22.2 inches)
  • Width: 222.0 mm (8.8 inches)
  • Weight:
    • Minimum weight: 2.1 kg (4.6 lb)
PCI expansion slotsSupports up to two PCIe adapters with the following requirements:
  1. When a compute-expansion node assembly is installed in an enclosure:

    • Two 2000-watt ac power supplies are required.

    • The other two node bays in the same enclosure must be installed with either of the following:

      • Another compute-expansion node assembly with one four-drive backplane installed in the compute node

      • Two node fillers

  2. In the compute node that comes with the PCIe expansion node assembly:

    • No RAID adapter should be installed in the compute node.

    • Only four-drive backplanes are supported.

    • No more than 12 DIMMs should be installed in the compute node.

    • When two GPU adapters are installed:

      1. Two processors are required in the compute node.

      2. Four-drive NVMe backplane is not supported.

  3. Concerning the GPU adapters installed in the node assembly:

    • Up to two 300 W passive GPU adapters (without fans) are supported.

    • The two GPU adapters must be of the same type.

    • When only one GPU adapter is installed, it has to be installed in the rear riser slot.
