Multiple Port, Multiple Server, Dual-Controller Storage Subsystem Configuration - IBM TotalStorage DS300 Hardware Installation And User's Manual

Multiple port, multiple server, dual-controller storage subsystem
configuration
This configuration can also be used for cluster operation. You can replace the two
Gb Ethernet switches shown in Figure 8 with one large Gb Ethernet switch that has
the required number of ports. Virtual Local Area Network (VLAN) can also be used
to isolate the two iSCSI networks, instead of a single switch.
The following illustration is an example of a multiple port, multiple server,
dual-controller storage subsystem configuration.
