Two Dedicated Networks
In this configuration, management traffic and data traffic are separated into two subnets. Management traffic uses the ports
assigned to the management subnet. All other subnets are designated as data only. Two switches for the management traffic
and two switches for the data traffic are recommended for redundancy and high availability. Multiple switches carrying a
particular subnet must be connected with an inter-switch link, trunk port, or switch stacking modules. If that subnet is assigned
to a particular VLAN, the inter-switch link or trunk port must allow that VLAN.
This configuration option is probably best in cases where security is an issue, where network administrators do not need
access to data traffic, where the amount of data traffic is such that it has a dedicated network, or where the network for data
traffic is completely separate from the management network.
Choose this option:
• To limit iSCSI traffic from the management network
• To isolate the subnets for network security
• If you want a dedicated broadcast domain reserved for iSCSI traffic
