8.3.3 DS400 dual controller fabric attachment
In case that more than two host systems should be attached with multiple paths
to a DS400 dual controller model, SAN switches are necessary. To prevent single
points of failure, two SAN switches or SAN directors should be used.
Important:
Assign logical drives within an individual array only to a single host
system in this configuration. Otherwise the access of a second host system
with to a logical drive may be interrupted, if the first host system forces a
controller failover for the array.
