EVA6400 storage system connections
Figure 23 (page 28)
shows a typical EVA6400 SAN topology:
•
The HSV400 controllers connect via four host ports (FP1, FP2, FP3, and FP4) to the Fibre
Channel fabrics. The hosts that will access the storage system are connected to the same
fabrics.
•
The HP P6000 Command View management server also connects to both fabrics.
•
The controllers connect through one loop pair to the drive enclosures. The loop pair consists
of two independent loops, each capable of managing all the disks should one loop fail.
