EVA6400 storage system connections
Figure 23 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 Command View EVA 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.
