Ds400 Single Controller Direct Attachment; Ds400 Single Controller Fabric Attachment - IBM TotalStorage DS300 Best Practices Manual

8.2.1 DS400 single controller direct attachment

The DS400 single controller model has two Fibre Channel ports. Thus it allows
the direct attachment of up to two host systems, each having a single path to the
DS400.

8.2.2 DS400 single controller fabric attachment

In case that more than two host systems should be attached to a DS400 single
control model, a SAN switch is necessary. Figure 8-2 on page 436 shows a
configuration with a SAN switch which allows additional host systems to be
connected to the DS400.
