Figure 1. Four Hosts in a Dual-Controller 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.
