Figure 2. Four Hosts in a Dual-Controller Configuration Using One HBA Each
Dual Path Data Configuration
In the following figure, up to two servers are directly attached to the RAID controller modules. If the host
server has a second Ethernet connection to the array, it can be attached to the iSCSI ports on the array's
second controller. This configuration provides improved availability by allowing two separate physical
paths for each host, which ensures full redundancy if one of the paths fail.
