Dual Path Data Configuration

In Figure 2-4, 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.

In Figure 2-5, up to two cluster nodes are directly attached to two RAID

controller modules. Since each cluster node has redundant paths, loss of a

single path still allows access to the storage array through the alternate path.
