Cable Management Network Servers

This topic describes nodes in the air-cooled cabinet with diagrams and pictures showing where to find the ports on the nodes and how to cable the nodes to the management network switches.

HPE Hardware

Dual Card Installations

The table below describes the cabling of dual card configurations. Also read notes in this section to see other possible customer-based configurations.

Device Port Linux Device Destination Name VLAN LAG

PCIe Slot 1 2 sun1 N/A N/A N/A N/A
ILO 1 None HMN leaf-bmc N/A HMN N/A

NOTES:

  • REQUIRED: Master 001 (ncn-m001) is required to have a site connection on OCP Port 2 for installation and maintenance.
  • RECOMMENDED: Masters 002 and 003 may optionally have a site connection on OCP Port 2 for emergency system access.
  • REQUIRED: Master 001 (ncn-m001) is required to have its BMC/iLO connected to the site.

Diagram of HPE Master Node Cabling

NOTE: Master 1 (ncn-m001) is required to have a site connection for installation and non-CAN system access. This can have several configurations depending on customer requirements/equipment:

  • Dual 10/25Gb card configurations as described in the table above should use PCIe Slot 1, Port 2 as a site connection if the customer supports 10/25Gb.
  • If the customer does not support 10/25Gb speeds (or connection type) and requires RJ45 copper or 1Gb, then a new and separate card will be installed on ncn-m001 and that card will provide site connectivity.
  • Another possibility (non-HPE hardware mainly) is that a built-in 1Gb port will be used if available (similar to Shasta v1.3 PoR on Gigabyte hardware).

HPE Storage Node Cabling

NOTES:

  • All ports are cabled.
  • OCP Port 1 and PCIE Slot 1 Port 1 (first ports) are bonded for the NMN, HMN and CAN.
  • OCP Port 2 and PCIE Slot 1 Port 2 (second ports) cabled but not configured in this release.

HPE Apollo 6500 XL645D

Diagram of Rear View of HPE Apollo 6500 XL645D

  • The XL645D has two servers in the same chassis.
  • The iLO BMC RJ45 port is a shared network port. Both iLO/BMC traffic and compute node traffic could transit this link.
    • Isolating this port to iLO/BMC only traffic is not possible within firmware configuration alone.
    • iLO configuration settings must be paired with management switch port settings to ensure only BMC traffic exits the port.
    • The iLO firmware must be set to tag traffic to VLAN 4. The switch port must be set to trunk VLAN 4.
  • Ports on the OCP card are numbered left-to-right: the far left port is port 1.

  • Two PCIe slots (chassis slots 21 and 22) are highlighted. One will contain the 1Gb management network card and one will be for the HSN.
  • The iLO BMC RJ45 port is a shared network port. Both iLO/BMC traffic and compute node traffic could transit this link.
    • Isolating this port to iLO/BMC only traffic is not possible within firmware configuration alone.
    • iLO configuration settings must be paired with management switch port settings to ensure only BMC traffic exits the port.
    • The iLO firmware must be set to tag traffic to VLAN 4. The switch port must be set to trunk VLAN 4.

Diagram of Gigabyte Master Node Cabling

NOTE: Master 1 (ncn-m001) is required to have a site connection for installation and non-CAN system access. In Shasta versions <=1.3 this connection was on ncn-w001. This can have several configurations depending on customer requirements/equipment:

  • The default configuration for Gigabyte systems uses the built-in 1Gb lan0 port for site connection on ncn-m001.
  • If the customer requires connectivity greater than 1Gb (or a different connection type), then a new and separate card will be installed on ncn-m001 and that card will provide site connectivity.

Diagram of Gigabyte UAN Cabling

NOTE that there are a couple configurations possible for LAN0:

  • Existing Gigabyte systems on Dell and Mellanox network hardware will use the (existing) Dell leaf-bmc port.
  • Any Gigabyte system on Aruba network hardware will use an Aruba 6300 (for the 1Gb port).
  • Optionally a 10/25Gb card could be added in an Aruba hardware system to match the HPE UANs.
