System Installation with ContentServer 3000 Series<br />

Network Diagram with 10 GbE Network<br />

The network topology diagram in Figure 3 shows a basic network configuration using<br />

ContentServers with 10 GbE NIC cards. Note that with the 10 GbE NIC card option, each controller<br />

has four ports: two 10 GbE ports on the add-in Ethernet card and two 1 GbE ports on the<br />

serverboard.<br />

In Figure 3, note the following:<br />

• Private VLAN 1 is a dedicated VLAN defined on the 1 GbE switch shown on the left. Private<br />

VLAN 2 is a dedicated VLAN defined on the 1 GbE switch shown on the right. The<br />

ContentDirectors must communicate on both private VLANs.<br />

• To allow failover, the Public VLAN indicated with the blue cables must also be connected to the<br />

switch or module from the Public VLAN indicated with the gray cables. The separate colors<br />

indicate failover configuration only; in reality these are the same VLAN.<br />

• The BMC connection indicated by turquoise cables is used for a troubleshooting utility called the<br />

Baseboard Management Console (BMC). This requires a 1 GbE connection from each controller<br />

on a ContentServer to the 1 GbE switch. The BMC cables should be connected to the Public<br />

VLAN.<br />

• ContentStores are connected to a ContentServer via SAS cables.<br />
