21 The VMware Channel IP Configuration page prompts you to configure the VMware Channel(s) IP
network addresses. Click Add for each available channel connection. For the Primary server, select from
a drop-down menu that lists all local IP addresses. Type the reciprocal IP address on the Secondary server
into the IP Address On Secondary text box. You must specify all VMware Channel IP addresses in
subnets outside of the normal Principal (Public) IP addressing schema so that VMware Channel traffic
routing uses the VMware Channel network card rather than the Principal (Public) network card. Click
OK. Repeat this step for additional NICs.
22 Review and adjust, if necessary, the default channel port. Click Next.
23 Select the Principal (Public) NIC(s). The IP address information is displayed for each NIC. Click Next.
vCenter Server Heartbeat software can be deployed in a configuration where both servers use the same
Principal (Public) IP address, for instance in a standard Local Area Network (LAN) deployment where
both machines are in the same subnet.
Alternatively, vCenter Server Heartbeat can be deployed where the Principal (Public) IP addresses differ,
for instance, in a Wide Area Network (WAN) deployment where the Primary and Secondary servers are
located in different sites and subnets where client access is therefore bound by the standard network
routing to allow the correct connectivity to the server according to its locale.
24 Select Use same IP addresses for Secondary (Recommended for HA secondary) or
Use different IP addresses for Secondary (Recommended for DR secondary).
You have the following options:
 For LAN installation or same subnet WAN installs, continue with Step 25.
 For a WAN installation with different subnets, go to Step 26.

OTE If the Secondary server is virtual, you will receive a warning message that the Secondary server
cannot be contacted. Disregard the warning and click No to proceed.
NOTE When the implementation spans multiple sites with firewalls between the servers, configure the
firewalls to allow traffic to pass through the default channel port or the manually configured channel port.
Consult the VMware knowledge base for additional information.
N
OTE Adjacent IP addresses should be reserved and used for the Principal (Public) IP address and the
Management IP addresses for the Primary and Secondary Servers when installing vCenter Server
Heartbeat on servers running Windows 2008.
