connection to the system management interfaces. Port 2 can also be used for iSCSI connectivity to
the system by hosts on the network. If more than one control enclosure is present in the system,
ensure that port 2 of every node canister is connected to the same network to provide access if the
configuration node fails.
Connecting Ethernet cables to 25 Gbps iSCSI 2-port host interface adapters
If you installed an optional 25 Gbps iSCSI 2-port host interface adapter, you can use Ethernet cables to
connect the system to your network.
About this task
Each Storwize V5000 Gen2 system has two onboard Ethernet ports, port 1 and port 2. When an optional
2-port 25 Gbps Ethernet host interface adapter (RoCE or iWARP) is installed, the Ethernet port number
starts at 3.
Note: The Ethernet cables are connected in pairs. Both canisters must have the same number of cables
connected.
Procedure
To install the cables, complete the following steps.
1. Identify the correct pair of Ethernet cables for the Ethernet ports labeled 3 in the left canister and the
right canister.
2. Connect the appropriate cable to each port.
3. For each additional pair of Ethernet ports in the right and left canisters, identify the correct pair of
cables and connect them.
Results
Figure 72 on page 70 shows the ports (labeled 3 and 4) on a 25 Gbps Ethernet (RoCE) adapter, as seen
on the back of a Storwize V5030E node canister.

Connecting Fibre Channel cables to a Fibre Channel adapter in the enclosure
If your system has one or more 4-port 16 Gbps Fibre Channel adapters installed, use Fibre Channel
cables to connect the two node canisters in the enclosure to the switches in the Fibre Channel SAN.
Procedure
Connect the required number of Fibre Channel cables to the node canisters in the control enclosure.
Note: Both canisters must have the same number of cables connected.
