2.2 SAN configuration planning
To connect a Storwize V5000 Gen2 system to a Fibre Channel (FC) SAN, you must first
install the optional 16 Gb FC adapters in every node canister that you connect. Ensure that
you use the correct fibre cables to connect the Storwize V5000 Gen2 to the Fibre Channel
SAN. With the FC cards installed, the Storwize V5000 Gen2 can be used to interface with FC
hosts, external storage controllers, and other Storwize systems that are visible on the SAN
fabric.
The Storwize V5010 and V5020 models support a single I/O group only and can migrate from
external storage controllers only. The Storwize V5030 supports up to two I/O groups that form
a cluster over the FC fabric. The Storwize V5030 also supports full virtualization of external
storage controllers.
The advised SAN configuration consists of a minimum of two fabrics that encompass all host
ports and any ports on external storage systems that are to be virtualized by the IBM Storwize
V5000 Gen2. The IBM Storwize V5000 Gen2 ports must have the same number of cables
that are connected, and they must be evenly split between the two fabrics to provide
redundancy if one of the fabrics goes offline (planned or unplanned).
