By using an IP SAN "cloud" Ethernet switch, the MD3000i RAID controller can support up to 16 hosts simultaneously with multiple connections per session. This solution supports either single- or dual-path data configurations, as well as either single or dual controller modules. Figure 2-4 shows how up to 16 standalone servers can be attached (via multiple sessions) to a single MD3000i RAID controller module through a network. Hosts that have a second Ethernet connection to the network allow two separate physical paths for each host, which ensures full redundancy if one of the paths fail. Figure 2-5 shows how the same number of hosts can be similarly attached to a dual MD3000i RAID controller array configuration. Hardware Installation 13
