Eight-socket storage rich

These configurations support up to eight processors, 24 drives and 17 rear PCIe slots.
The eight-socket storage rich configurations support six or eight processors with the following requirements/
capabilities:
• Only 8100 series processors are supported.
• Fan 1 to 6 are required to be installed.
• The upper compute tray is installed in the upper tray slot.
• Up to 24 drives are supported.
See the following for the support variations depending on number of processors that are installed:
• "Eight-socket storage rich, six processors" on page 18
• "Eight-socket storage rich, eight processors" on page 19
Eight-socket storage rich, six processors
This configuration comes with six processors, requires at least four 1100-watt or two 1600-watt PSUs, and
supports up to:
• 72 memory modules.
• 13 rear PCIe slots.
See the following tables for the location of the supported components.
