Storage System Connections
Figure 6 shows a typical Enterprise Virtual Array 3000 SAN topology:
■ The HSV controllers connect via ports FP1 and FP2 to two Fibre Channel
fabrics. The hosts that will access the storage system are connected to the
same fabrics. Note that FP1 on each controller is connected to a different
fabric to balance the I/O load.
■ Command View EVA, which runs on the storage management appliance, also
connects to both fabrics.
■ The controllers connect through two FC loops to the drive enclosures. The
loop pair consists of two independent loops, each capable of managing all the
disks should one loop fail.
