Figure 1- 5. Multi-NIC Configuration
The IP address a client uses to connect to the active server (the Principal (Public) IP address) must be congured
as a static IP address and not DHCP (Dynamic Host Conguration Protocol) enabled. In Figure 1-4 and Figure
1-5, the Principal (Public) IP address is congured as 192.168.1.127.
LAN Deployment
When deployed in a LAN, the Principal (Public) NIC on the active server is congured with both a unique
permanently assigned Management IP address for administrative access and the Principal (Public) IP address
which allows trac from clients. The Principal (Public) NIC on the passive server is congured to use its
unique permanently assigned Management IP address. When a switchover or failover occurs, the Principal
(Public) IP address assigned to the currently active server is removed and reassigned to the new active server.
The new passive server remains accessible to administrators via the Management IP address but is not visible
to clients. The newly active server then starts accepting trac from clients.
The NICs on the active and passive servers used for the VMware Channel are congured so that their IP
addresses are outside of the subnet range of the Principal (Public) network. These addresses are referred to as
VMware Channel addresses.
During installation, setup will switch o NetBIOS for the VMware Channel(s) on the active and passive servers
as this connection remains live and both the passive and active machines have the same NetBIOS name.
Following vCenter Server Heartbeat installation (runtime), NetBIOS is disabled across the channel(s).
