storage system connections
Figure 3 shows a typical EVA3000 SAN topology:
The HSV10 0 controllers connect via two host ports (FP1 and FP2) to the Fibre Channel fabrics.
The hos
ts that will access the storage system are connected to the same fabrics.
The HP Command View EVA management server also connects to the fabric.
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. The
contr
ollers connect directly to the disk enclosures.
