Dell PowerStore PowerStore T and Q Networking Guide for Storage Services

Cable the nodes to the ToR switches

The following steps provide an example of cabling the PowerStore T model appliance nodes to two Dell PowerSwitch Series S4148 Top-of-Rack (ToR) switches.

The following instructions apply to the iSCSI storage network, and the ToR switches configured in Configuring PowerStore storage networks with Dell PowerSwitch Series S4148 Top-of-Rack switches .

The following example uses port 1 on I/O Module 0. However, use any available port on any I/O module if your nodes have been configured with I/O modules.

NOTE:Ports 0 and 1 of the 4-port card are reserved for the cluster network with all PowerStore T model appliances. Ports 2 and 3 of the 4-port card in PowerStore 500T model appliances are reserved for connectivity to the 24 Drive 2.5-Inch NVMe (ENS24) expansion enclosures.

As demonstrated below, when cabling the nodes to the ToR switches the bottom node (A), and the top node (B) must be cabled to opposite switches.

Figure 1. Cable the additional port
Diagram demonstrates the steps to connect the node ports to the ToR switch ports for the iSCSi and Replication and Block Import networks used in the sample configuration.
  1. Connect Port 1 in I/O Module 0 of the bottom Node A to Port 6 of the bottom switch (Switch1).
  2. Connect Port 1 in I/O Module 0 of the top Node B, to Port 49 of the top switch (Switch2).
