Because the secondary server in a redundant pair will be set up to run exactly the same functions (except for configuration functions) as the primary server, the secondary server in a redundant pair must be identical to the primary server; that is, the disk, memory, and input/output peripherals should be identical.
Cabling to devices may place the primary and redundant servers on the same or different cables. The type of cabling used will depend on the requirements of the device. Communications interface software supported by CIMPLICITY Server Redundancy attempts to minimize network traffic to and from the secondary server.
You can connect a device to redundant servers via different cables.
Or, you can connect a device to redundant servers on the same cable.
