protection, use three switches. Connect one (DS2200) or two (DS6200/DS4200) ports from each controller module
to the left switch. Connect one (DS2200) or two (DS6200/DS4200) ports from each controller module to the right
switch.
Connect one (DS2200) or two (DS6200/DS4200) ports from each controller module to the middle switch. Use
multiple switches to avoid a single point of failure inherent to using a single switch, and to physically isolate
replication traffic from I/O traffic.
