3 Type the remote server IP address.

4 To change the VMware Channel IP addresses, select and edit the entry in the table.

5Click Next or Finish.

Configuring the Default Channel Port

VMware Channel uses the Default Channel Port to communicate between the Primary and Secondary server.

Do not change this port unless another application is using it. To change the Default Channel Port, click the

Channel tab, edit the default entry (57348), and click Next or Finish.

Configuring Low Bandwidth Module

This feature is enabled during installation. To disable this feature, click the Channel tab and clear the Low

Bandwidth Optimization check box. When enabled, the VMware Channel optimizes communications for low

bandwidth connections. Low Bandwidth Optimization (LBO) stores data on disk rather than in memory and

is essential for WAN installations or when bandwidth is limited.

To enable LBO, click the Channel tab, select the check box to enable the feature and click Next or Finish.

Configuring Public IP Addressing

vCenter Server Heartbeat servers are configured with one or more Principal (Public) IP addresses. These are

the addresses used by clients of the protected application to connect to the application. Typically, there is one

Principal (Public) IP address.

You must configure all of the Principal (Public) IP addresses on both Primary and Secondary servers. On the

passive server, all traffic to and from these Principal (Public) IP addresses is blocked. On the active server, all

traffic passes through. When the server roles switch, the IP filtering mode also switches, so client systems

always connect to the Principal (Public) IP addresses on the server that is currently active. When the vCenter

Server Heartbeat service shuts down, the filtering remains in place so no IP address conflicts occur between

the two servers.

NOTE This feature is designed for implementations where the available throughput on the VMware Channel

is slower than 10 Mbit/s. Do not enable the Low Bandwidth Module in a LAN, this feature is not designed to

work in a LAN where the throughput is much faster.
