Connecting the Appliance to Hosts and Storage Arrays
82
Continuous Access Storage Appliance Installation and Maintenance Guide
Directly connecting hosts and storage to the appliance
shows three hosts and two storage arrays directly connected to the appliance. In this
example, assume the following:
■
I0 from each peer node connects to the shared storage array.
■
From host 1, HBA 1 connects to T0 on peer node 0, and HBA 2 connects to T0 on
peer node 1.
■
From host 2, HBA 1 connects to T2 on peer node 0, and HBA 2 connects to T2 on
peer node 1.
■
From host 3, HBA 1 connects to T1 on peer node 0, and HBA2 connects to T1 on
peer node 1.
■
From storage array 1, controller 0 connects to I1 on peer node 0, and controller 1 connects
to I1 on peer node 1.
■
From storage array 2, controller 0 connects to I2 on peer node 0, and controller 1 connects
to I2 on peer node 1.
■
The LAN interface and Gigabit Ethernet connections exist but are not shown.
Note:
When connecting hosts and storage arrays directly to the appliance, ensure that the topology
for the target ports is set to Loop. When using switches, set the topology to Point to Point. Refer to
“
Configuring Target Ports
” in the
HP OpenView Continuous Access Storage Appliance System
Administrator’s Guide
for more information.
