Figure 2-2. Up to Four Direct-Attached Servers, Single-Path Data, Dual Controllers (Duplex)
Dual Path Data Configuration
In Figure 2-3, up to two servers are directly attached to the MD3000i RAID controller module. 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.
