A technique controls a network switch having a set of ports. The technique involves configuring the network switch to provide an initial set of communications paths between the ports. The initial set of communications paths defines an initial communications path topology within the network switch. The technique further involves receiving a configuration command which identifies a particular operating mode of the data storage system after configuring the network switch to provide the initial set of communications paths within the network switch. The technique further involves reconfiguring the network switch to provide a new set of communications paths between the ports in response to the configuration command. The new set of communications paths (i) defines a new communications path topology within the network switch, the new communications path topology being different than the initial communications path topology, and (ii) supports the particular operating mode of the data storage system.
