Network cable connections worksheet

Edit online

During the planning process, complete the cable-connection tables below with the locations of the cable connections for each control enclosure in the system.

Ethernet connections

Each node canister in the control enclosure connects over an Ethernet cable from Ethernet port 1 of the canister to an enabled port on your Ethernet switch or router. Ethernet port 1 is for accessing the management GUI, for accessing the service assistant GUI for the node canister, and for iSCSI host attachment. You can attach an Ethernet cable from Ethernet port 2 on the canister to your Ethernet network. Port 2 can be used for the management GUI and for iSCSI host attachment. Ports 3 and 4 are for iSCSI attachment only.

Note: The ports on the upper node canister (canister 1) are numbered from right to left. However, the ports on the lower node canister (canister 2) are numbered from left to right.

For more information on other Ethernet cables and their respective standard, refer to Planning network cable connections.

Ethernet cable standards

The following table provides a list of Ethernet cable standards.
Table 1. Ethernet cable standards
Ethernet port type Cable type Minimum standard Connector
1 Gbps Ethernet technician port TP Cat 5e RJ45
10 Gbps onboard Ethernet ports TP Cat 6 (up to 55 m); Cat 6a or Cat 7 (up to 100 m) at 10 Gbps; Cat 5e at 1 Gbps RJ45
25 Gbps Ethernet host interface adapter (must be ordered) Optical OM3 (up to 70 m); OM4 (up to 100 m) LC
100 Gbps Ethernet host interface adapter (4 lanes of 25 Gbps) Optical/wire with transceivers OM3 (up to 70 m); OM4 (up to 100 m) LC

Ethernet onboard ports

Record the node canister onboard Ethernet port connections in the following table.

Speed (1 Gbps, 10 Gbps)         1 Gbps

Ethernet networking adapter ports

Each node canister also supports optional 2-port 25 Gbps internet Wide-area RDMA Protocol (iWARP) or RDMA over Converged Ethernet (RoCE) Ethernet adapters. The following guidelines must be followed if 25 Gbps Ethernet adapters are installed.
  • iWARP and RoCE Ethernet adapters can be mixed within a node canister.
  • Fibre Channel adapters are installed before Ethernet adapters, beginning with slot 1, then slot 2, and slot 3.
  • Ethernet adapters are installed beginning with the first available slot.
  • To connect to expansion enclosures, you must order a 4-port 12 Gbps SAS adapter that is installed in slot 3. However, only ports 1 and 3 are used to establish a SAS connection.
Use the following table to record the node IP address for any port that is used for node-to-node RDMA communication. The node IP, subnet mask, gateway, and VLAN ID are used for node-to-node communications

Fibre Channel connections

Each node canister supports one or two 4-port 32 Gbps FC adapters or 4-port 16 Gbps FC adapters. The adapters are installed based on the following guidelines. Use the following table to record the FC port connections.

  • The first Fibre Channel adapter must be installed in adapter slot 1.
  • If more Fibre Channel adapters are needed, they are installed in slots 2 and 3.
