Host-agent (in-band) management method
This method requires that host-agent software be installed on the host server. The
host-agent software enables the DS3000 Storage Manager client program to
manage the DS3200 storage subsystem by using the same 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. The client software is installed
on the management station. Figure 24 shows the host-agent (in-band) management
method.

Note: The client software is installed on one or more management systems, or on the host computer.
Direct (out-of-band) management method
This method uses Ethernet connections from a management station to each
controller in the storage subsystem. You must install at least one management
station. The management station can be the host or a workstation on the Ethernet
network. The client software is installed on the management station. 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 25 on page 37 shows the direct (out-of-band)
management method.
Note: Do not connect the DS3200 storage subsystem Ethernet ports to a public
network or public subnet. To minimize security risks, create a private network
between the DS3200 storage subsystem and the management station.
