Network-Attached Configurations
You can also cable the host servers to the RAID controller module iSCSI ports through industry-standard 10 Gbps or 1 Gbps Ethernet switches. An iSCSI configuration that uses Ethernet switches is frequently referred to as an IP SAN. By using an IP SAN, the PowerVault MD3660i series storage array can support up to 64 hosts simultaneously. This configuration supports either single or dual path data configurations and either single or dual controller modules.
The following figure shows up to 64 stand-alone servers attached (using multiple sessions) to a dual RAID controller module configuration 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 fails. It is recommended you use two switches for more redundancy. However, single switch configuration is also supported.
