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 41
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 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 42 on page 49 shows the direct (out-of-band) management method.
Note: Do not connect the DS3500 storage subsystem Ethernet ports to a public
network or public subnet. To minimize security risks, create a private network
between the DS3500 storage subsystem and the management station.
