Four-socket upgradable / storage rich

This configuration allows a simple upgrade to eight-socket configurations in the future, while supports up to 24 drives and ten rear PCIe slots.

The four-socket upgradable / storage rich configurations only supports four processors with the following requirements/capabilities:

  • Only 8100 series processors are supported, and they must be configured in a ring topology.
  • The upper compute tray is installed in the upper tray slot.
  • All 12 fans are required to be installed.
  • Up to 24 drives are supported.
This configuration allows a simple upgrade to 8-socket ones. See Eight-socket storage rich for details about 8-socket configurations.

This configuration comes with four processors, requires at least two 1100/1600-watt PSUs, and supports up to:

  • 48 memory modules.
  • Ten rear PCIe slots.

See the following tables for the location of the supported components.
