The four-socket upgradable configurations support two or four processors with the following requirements/
capabilities:
• Only 8100 series processors are supported.
• Fan 1 to 6 are required to be installed.
• The upper tray filler is installed in the upper tray slot.
• Up to 12 drives (bay 0 - 11) are supported.
See the following for the support variations depending on number of processors that are installed:
• “Four-socket upgradable, two processors” on page 16
• “Four-socket upgradable, four processors” on page 16
Notes:
• When four processors are installed, they must be configured in a ring topology.
• These configurations allow a simple upgrade to 8-socket ones. See “Eight-socket storage rich” on page
18 for details about 8-socket configurations.
