Partition Configuration
Before configuring your library, review the following examples and diagrams. These
are only a few examples of a partition configuration; an incredible number of
configurations are possible.

Partitions Using QIP-Attached Drives
Figure 2-8 is a simple representation of how one QIP-based library partition is
connected to a SAN, and how the QIPs in the partition connect to the drives assigned
to that partition.
connected to a SAN, and how the QIPs in the partition connect to the drives assigned
to that partition.
This example partition is configured to use 12 drives, which are controlled by three
Fibre Channel QIPs (F-QIPs). F-QIP 3 receives and processes the robotics commands
for the partition. All drives on each F-QIP are visible through each QIP’s Port B. This
partition looks like a unique library to the server on the other side of the Fibre Channel
hub or switch, as would any partition configured in a Spectra T950 library.
