IBM DS3200 Storage Subsystem manual Host-agent in-band management method

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.

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.
