20 Hardware Installation
Network-Attached Configurations
You can also cable the host servers to the RAID controller module iSCSI ports
through industry-standard 1GB Ethernet switches. An iSCSI configuration
that uses Ethernet switches is frequently referred to as an IP SAN. By using an
IP SAN, the PowerVault MD3200i 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.
Figure 2-6 shows up to 64 stand-alone servers attached (using multiple
sessions) to a single 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 2-7 shows how the same number of hosts can be similarly attached
to a dual RAID controller module configuration.
