EVA6000 storage system connections
Figure 3 shows a typical Enterprise Virtual Array 6000 SAN topology:
• The HSV200 controllers connect via two host ports (FP1 and FP2) to the Fibre Channel fabrics.
The hosts that will access the storage system are connected to the same fabrics.
• HP Command View EVA, which runs on the storage 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. Two FC
loop switches are used to connect the controllers to the disk enclosures.
