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 server). You will connect the cables to each storage server controller later when you install the storage server. Figure 24 on page 36 shows the direct (out-of-band) management method.

Note: Do not connect the DS4100 storage server Ethernet ports to a public network or public subnet. It is strongly recommended that you create a private network between the DS4100 storage server and the management station.
