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 52 shows the host-agent (in-band) management
method.

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 53 on page 72 shows the direct (out-of-band) management method.
You can either use the default controller Ethernet IP addresses for out-of-band
connection or change the default controller Ethernet IP addresses by using
Dynamic Host Configuration Protocol (DHCP) or Storage Manager client. Refer to
the DS4000 Storage Manager Installation, User's and Maintenance Guide for the
appropriate operating system for more information on setting the management
connections and installing the DS4200 Express Storage Subsystem management
software.
For a listing of default IP addresses, see "Connectors, switch, and enclosure ID" on
page 8.
