Direct (out-of-band) management method

This method uses Ethernet connections from a management station to each
controller. You must install at least one management station. The management
station can be the host or a workstation on the Ethernet network. A management
station will have the client software installed. Attach Ethernet cables to each
management station (one pair per storage subsystem). You will connect the cables
to each storage subsystem controller later when you install the storage subsystem.
Figure 62 on page 84 shows the direct (out-of-band) management method.
Note: Do not connect the DS4800 Storage Subsystem Ethernet ports to a public
network or public subnet. It is strongly recommended that you create a
private network between the DS4800 Storage Subsystem and the
management station.
