Host-agent (in-band) management method
This method requires host-agent software that you install on the host server. The
host-agent software allows the DS4000 Storage Manager client program to manage
the DS4000 Storage Subsystem using the same fibre channel connections between
the host server and the storage subsystem. You must install at least one
management station and a software agent host. The management station can be
the host or a workstation on the Ethernet network. A management station will have
the client software installed. Figure 64 shows the host-agent (in-band) management
method, where a fibre channel I/O path connects two DS4800s together and to the
host server, which is connected to a management station via an Ethernet network.

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.

two fibre channel I/O paths connect two DS4800s together and to the host server,
