Chapter 2 — Architecture Overview
Fibre Channel Port Configurations
One or both of the external ports on the exporting controller can be used to
provide the network connectivity for the library partitions.
Single Port Connectivity The simplest configuration uses a single library
partition and only one of the interface ports on the exporting controller.
This configuration works well when only a single host is connected to the
library.
Dual-Path Connectivity A slightly more complex configuration uses both
interface ports on the exporting controller with each connected to a
different library partition. Each port is used as an independent
communications path. From a host perspective, each port is viewed as a
unique, independent path to a partition. The two ports can be connected to
the same or possibly different storage area networks (SANs). The library
processes the motion commands and relays them to the partitions in the
order that they are received. This is a way to provide limited visibility
between the partitions. If you have more than two partitions you can use
additional controllers to provide additional isolation between partitions.
