replication occurring on the same network.
For optimal protection, use multiple switches for host I/O and replication.
• Connect two ports from each controller module in the left storage enclosure to the left switch.
• Connect two ports from each controller module in the right storage enclosure to the right switch.
• Connect two ports from the controller modules in each enclosure 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.
