Four-socket performance / storage rich

These configurations meet the expectations of high-performance and low costs, while support up to 24
drives and 13 rear PCIe slots.
The four-socket performance / storage configurations support two to four processors with the following
requirements/capabilities:
• Fan 1 to 6, 7, 9, and 11 are required to be installed.
• The upper storage 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:
