vCenter Server with SQL Server on the Same Host
To ensure adequate performance in 20+ host or 200+ virtual machine environments, VMware recommends
that SQL Server and vCenter Server be installed on separate physical disk drives. VMDKs must be on separate
datastores to avoid potential disk bottlenecks.
vCenter Server with SQL Server on a Separate Host
When installing vCenter Server Heartbeat in an environment where SQL Server is on a separate host from
vCenter Server, repeat the installation process for the Primary and Secondary server specifically for the SQL
Server.
Network Requirements
When deployed in a LAN environment, vCenter Server Heartbeat requires that both servers use the same
Principal (Public) IP address. Each server also requires a separate VMware Channel IP address on a separate
dedicated subnet..
Primary Server
Three NICs (1 x Principal (Public); 2 x Vmware Channel) are recommended for redundancy in the event one
VMware channel fails. A minimum of two NICs (one for the Principal (Public) connection, and one for the
VMware Channel) are required in this configuration.
 Principal (Public) Network connection configured with the following:
 Static IP address
 Correct network mask
 Correct Gateway address
 Correct preferred and secondary (if applicable) DNS server address
 NetBIOS enabled
 VMware Channel network connection(s) configured with the following:
 Static IP address in a different subnet than the Principal (Public) network with a different IP address
than the Secondary server VMware Channel NIC
 Correct network mask
 No Gateway IP address
 No DNS server address
 NetBIOS enabled (disabled during the installation process)
Secondary Server
Networking components on the Secondary server must be configured as follows:
 Same number of NICs as the Primary server
 Principal (Public) network connection configured with temporary network settings
 VMware Channel network connection(s) configured with the following:
N
OTE Ensure that all VMware components are bound to the Principal (Public) IP address on the Principal
(Public) network adapter and that the Principal (Public) network adapter is listed first in the bind order of the
Network Connections > Advanced > Advanced Settings window.
NOTE vCenter Server Heartbeat can be configured to support teamed NICs but requires additional
configuration steps. See Knowledge Base article 1027288 for more information about teamed NICs.
