CMOD Population Rules

The Oracle Server X7-8 supports four and eight CMOD configurations. Each CMOD supports a single socket containing a single processor. Each CMOD contains one Intel Xeon vx processor 28-core (shelf 4) processor.

For the single 4-socket (1x4) server configuration:

  • System Module (SMOD) SMOD0 System A and SMOD1 System B must be installed, but only SMOD0 is active.

  • CPU modules (CMODs) must be installed in slots 0-3. CMOD slots 4-7 are empty.

  • All eight dual PCIe card carrier (DPCC) slots must be installed but only DPCC slots 1, 2, 3 and 4 are active.

    PCIe slots 5, 6, 7, and 8 are nonfunctional in 4-socket systems.

  • All eight fan modules (FMs) must be installed but only FMs 0-3 are active.

  • Both fan frames must be installed.

  • PS2 and PS3 are installed and active. PS0 and PS1 are also installed, but inactive. PS2 and PS3 power System A. PS0 and PS1 power System B.

    All four AC power connectors on the back panel must be attached with grounded AC power cords.

  • Storage drive bays in System B may have filler panels installed.

For the dual 4-socket server configuration:

  • System Module 0 (SMOD0) System A and SMOD1 System B must be installed.

  • CPU Modules (CMODs) must be installed in slots 0-7.

  • Dual PCIe card carrier (DPCC) slots 0-3 and DPCC slots 4-7 must be installed and are active.

  • All eight fan modules (FMs) must be installed. All FMs must be active in the dual 4-socket configuration.

  • Both fan frames must be installed.

  • PS2 and PS3 are installed and active. PS0 and PS1 are also installed and active. PS2 and PS3 power System A. PS0 and PS1 power System B.

  • All four AC power connectors on the back panel must be attached with grounded AC power cords.

For the single 8-socket (1x8) server configuration:

  • System Module 0 (SMOD0) System A and SMOD1 System B must be installed.

  • Eight CPU Modules (CMODs) must be installed in slots 0-7.

    In an 8-socket configuration, System A must have Intel Xeon 81xx series processors installed, and System A and System B processor SKUs and memory (capacity and number of DIMMs per CMOD) must be identical.

  • All eight dual PCIe card carrier (DPCC) slots 0-7 must be installed and must be active.

  • All eight fan modules (FMs) must be installed and all FMs must be active.

  • Both fan frames must be installed.

  • PS2 and PS3 power System A. PS0 and PS1 power System B.

  • All four AC power connectors on the back panel must be attached with grounded AC power cords.


Note -  During Oracle Server X7-8 reconfiguration, administrators will need to manually clear all existing faults before a 4-socket to 8-socket mode change.
