  • Page 52: Cabling For Replication

    • Ensure that all ports assigned for replication are able to communicate appropriately with the replication system (see the CLI Reference Guide for more information): For virtual replication, use the CLI query peer-connection command. • Allow two ports to perform replication. This permits the system to balance the load across those ports as I/O demands rise and fall.

Using two switches in tandem avoids the potential single point of failure inherent to using a single switch;...
