vCenter Server Heartbeat Introduction
This chapter introduces vCenter Server Heartbeat and provides an overview of the vCenter Server Heartbeat
concepts. It contains the following sections:
“vCenter Server Heartbeat Protection” on page 7
“Communications” on page 9
vCenter Server Heartbeat Protection
vCenter Server Heartbeat is a Windows based service specifically designed to provide high availability
protection for vCenter Server configurations without requiring any specialized hardware.
Server Protection
Two instances of vCenter Server Heartbeat regularly send “I’m alive” messages and message
acknowledgments to one another over a network connection referred to as the VMware Channel to detect
interruptions in responsiveness. If the passive server detects that this monitoring process (referred to as the
heartbeat) has failed, it initiates a failover as illustrated in Figure 1-1.
Figure 1-1. Failover
1
VMware, Inc. 7
QuickStart Guide
A failover is similar to a switchover but is used in more urgent situations, such as when the passive server
detects that the active server is no longer responding. This can occur when the active server hardware fails,
loses its network connections, or otherwise becomes unavailable. Rather than the active server gracefully
closing, the passive server determines that the active server has failed and requires no further operations. In a
failover, the passive server immediately assumes the active server role.
Network Protection
vCenter Server Heartbeat proactively monitors the active server to verify that it can communicate with the rest
of the network. vCenter Server Heartbeat polls defined nodes around the network, including the default
gateway, the primary DNS server, and the global catalog server at regular intervals. If all three nodes fail to
respond, for example, in the case of a network card failure or a local switch failure, vCenter Server Heartbeat
can initiate a switchover, allowing the Secondary server to assume an identical network identity as the Primary
server.
Application Protection
vCenter Server Heartbeat running on the active server locally monitors the applications and services it has
been configured to protect through the use of plug-ins.
If a protected application fails, vCenter Server Heartbeat first tries to restart the application on the active server
(1). If restarting the application fails, then vCenter Server Heartbeat can initiate a switchover (2).
Figure 1-2. Switchover
A switchover gracefully closes any protected applications that are running on the active server and restarts all
of them on the passive server, including the application or service that caused the failure as illustrated in
Figure 1-2.
Performance Protection
vCenter Server Heartbeat monitors application services and specific application attributes to ensure that
protected applications are operational and not in an unresponsive or stopped state. This level of monitoring is
fundamental in ensuring that applications are available to users.
In addition to monitoring application services, vCenter Server Heartbeat can also monitor specific application
attributes to ensure that they remain within normal operating ranges. Similar to application monitoring,
various rules can be configured to trigger specific corrective actions whenever these attributes fall outside of
their respective ranges.
8 VMware, Inc.
Chapter 1 vCenter Server Heartbeat Introduction
Data Protection
Once installed, vCenter Server Heartbeat configures itself to protect files, folders, and even the registry
settings for vCenter Server on the active server by mirroring these in real-time to the passive server. If a failover
occurs, all files protected on the failed server are available after the failover, hosted on the Secondary server.
Figure 1-3. Apply Process
Communications
The VMware Channel is a crucial component of the setup and can be configured in a number of ways.
Both the Primary and Secondary servers must have two or more network interface connections (NICs).
The Principal (Public) network requires one NIC. The VMware Channel uses a separate NIC, a private
connection used for control and data transfer between the pair of servers.
The VMware Channel might use a second pair of NICs to provide a degree of redundancy. In this case, the
VMware Channel has a Dual Channel if more than one dedicated NIC is provided for the VMware Channel
on each server. To provide added resilience, the communications for the second channel must be completely
independent from the first channel – they must not share any switches, virtual switches, routers or the same
WAN c o n nect i o n.
VMware, Inc. 9
QuickStart Guide
Figure 1-4. Communication between Primary and Secondary Servers
The IP address a client uses to connect to the active server (the Principal (Public) IP address) must be
configured as a static IP address (not DHCP enabled). In the example in Figure 1-4, the IP address is
configured as 192.168.1.127.
The Principal (Public) NICs on the passive server are configured to use the same IP address as that of the active
server but are prevented from communicating with the live network through an IP packet filtering system
installed with vCenter Server Heartbeat. This packet filter prevents traffic using the Principal (Public) address
from being committed to the wire. It also prevents NetBIOS traffic utilizing other IP addresses on the NIC from
being sent to prevent NetBIOS name resolution conflicts.
The NICs on the active and passive servers used for the VMware Channel are configured so that their IP
addresses are outside of the Principal (Public) networks subnet range. These addresses are termed the
VMware Channel addresses.
Following the restore and after the vCenter Server Heartbeat installation completes (runtime), NetBIOS is
disabled across the channel(s). This occurs during installation to prevent a name conflict, which occurs when
both servers have the same name.
The NICs that support connectivity across the VMware Channel can be standard 100BaseT Ethernet cards
providing a throughput of 100Mbits per second across standard Cat-5 cabling.
When configured for a WAN deployment, the VMware Channel uses static routes over switches and routers
to maintain continuous communications independent from corporate or public traffic.
vCenter Server Heartbeat software is installed on a Primary server and a Secondary server. These names refer
to the physical hardware (identity) of the servers.
The Secondary server has the same name, same file and data structure, same network address, and can run all
the same applications and services as the Primary server.
Only one server name and network address can be visible on the same network at any one time. One of these
two servers is live on the Principal (Public) network and serves the protected applications. This is the active
server. The other server is hidden from the Principal (Public) network, remains as a ready standby server, and
is the passive server.
The vCenter Server Heartbeat software is symmetrical in almost all respects, and either the Primary Server or
the Secondary server can take the active role and provide the protected application to users.

Overview
2
vCenter Server Heartbeat is a versatile solution that provides you with complete protection of vCenter Server
and SQL Server. It can be deployed in a LAN for high availability or across a WAN to provide disaster recovery.
vCenter Server Heartbeat can protect vCenter Server and SQL Server installed on the same server, or protect
vCenter Server and SQL Server on separate servers. This flexibility enables vCenter Server Heartbeat to protect
vCenter Server when using remote databases other than SQL Server.
Prior to installing vCenter Server Heartbeat, select the deployment options you intend to use. The installation
process prompts you to select options throughout the procedure to create the configuration you want.
Environmental Prerequisites
vCenter Server Heartbeat cannot protect a server configured with the following roles: domain controller,
global catalog, or DNS. Please note, because vCenter Server Heartbeat only protects the vCenter Server and
SQL Server applications, no other critical business applications should be installed on the server.
Common Requirements
The following requirements are in addition to those required for vCenter Server and SQL Server.

connections bind order. (Network Connections > Advanced > Advanced Settings).
Verify that the Managed IP setting in the Virtual Infrastructure Client is the same IP address used for the
vCenter Server Heartbeat Principal (Public) IP address.
Server Architecture Options
The selected server architecture affects the requirements for hardware and the technique used to clone the
Primary server.
Virtual to Virtual (V2V)
V2V is the supported architecture if vCenter Server is already installed on the production (Primary) server
running on a virtual machine. The Secondary virtual machine must meet the minimum requirements.
The specifications of the Secondary virtual machine must match the specifications of the Primary virtual
machine as follows:
Similar CPU (including resource management settings)
Memory configuration (including resource management settings)
Appropriate resource pool priorities
OS version and Service Pack
12 VMware, Inc.
Chapter 2 vCenter Server Heartbeat Installation
Each virtual machine used in the V2V pair must be on a separate ESX host to guard against failure at the
host level.
Each virtual NIC must use a separate virtual switch.
Physical to Virtual (P2V)
The P2V architecture is used when the environment requires a mix of physical and virtual machines. The
Secondary virtual machine must meet the minimum requirements.
The specifications of the Secondary virtual machine must match the Primary physical server as follows:
Similar CPU
Identical Memory
OS version and Service Pack
The Secondary virtual machine must have sufficient priority in resource management settings so that
other virtual machines do not impact its performance.
Each virtual NIC must use a separate virtual switch.
Physical to Physical (P2P)
P2P architecture is used in environments where both the Primary and Secondary servers are physical servers.
Use of P2P limits the installation options as it requires use of the Install Clone technique. This architecture
requires attention to detail when preparing for installation as both hardware and software must meet specific
prerequisites.
Primary Server
The Primary server must meet the hardware and software requirements specified in “Common Requirements”
on page 11.
Secondary Server
The Secondary server operates as a near clone of the Primary server and must meet the following
requirements.
Hardware
Hardware should be equivalent to the Primary server to ensure adequate performance when the server is in
the active role:
Similar CPU.
Similar memory.
Identical number of NICs to the Primary server.
Drive letters must match the Primary server.
Available disk space must be greater than or equal to the Primary server.
Advanced Configuration and Power Interface (ACPI) compliance must match the Primary server. The
vCenter Server Heartbeat Standard implementation process assumes identical ACPI compliance on both
machines. If not, contact VMware Support at www.vmware.com/support for further information.
Software
Software on the Secondary server must meet the following requirements.
OS version and Service Pack version must match the Primary server.
OS must be installed to the same driver letter and directory as on the Primary server.
Machine name must be different from the Primary server prior to installing vCenter Server Heartbeat.
VMware, Inc. 13
QuickStart Guide
Set up a workgroup prior to installing vCenter Server Heartbeat.
System date, time and time zone settings must be consistent with the Primary server.
Cloning Technology Options
Cloning the Primary server to create a near identical Secondary server involves different techniques
depending on the selected server architecture.
Supported Pre-Clone Technologies
The following cloning technologies are supported for creating Pre-Cloned images for use as a Secondary
server:
VMware Converter for “Physical to Virtual (P2V)” on page 13.
VMware vCenter virtual machine cloning for “Virtual to Virtual (V2V)” on page 12.
Supported Install Clone Technologies
Installation of vCenter Server Heartbeat provides support for NTBackup on Windows 2003 and Wbadmin on
Windows Server 2008 for automated Install Cloning. This process is automated but requires meeting all
prerequisites for the Secondary server specified in “Physical to Physical (P2P)” on page 13.

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.
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.
14 VMware, Inc.
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.
To ensure proper failover, increase the default Heartbeat interval for the vCenter Server from 20 to 30 seconds.
vCenter Server Only
The vCenter Server Only option requires a single iteration of the installation process because the database is
not protected.
To ensure proper failover, increase the default Heartbeat interval from 20 to 30 seconds on the server running
vCenter Server. This configuration is required anytime SQL Server is not installed on the same host as vCenter
Server.
Network Options
Networking requirements are contingent upon how vCenter Server Heartbeat is deployed. To deploy as a
High Availability (HA) solution, a LAN configuration is required. To deploy vCenter Server Heartbeat for
Disaster Recovery (DR), a WAN configuration is required.
Chapter 2 vCenter Server Heartbeat Installation
LAN
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.
N
OTE When installing vCenter Server Heartbeat in a LAN environment, do not enable the Low Bandwidth
Module as this is designed for WAN deployments.
Primary Server
Three NICs (1 x Public; 2 x Channel) are recommended for redundancy in the event one channel fails. A
minimum of two NICs (one for the Channel, and one for the Public) are required in this configuration.
Split-brain avoidance should be configured.
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
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 channel NIC
Correct network mask
No Gateway IP address
No DNS server address
NetBIOS enabled (disabled during the installation process)
VMware, Inc. 15
QuickStart Guide
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
Channel network connection(s) configured with the following:
WAN
Deploying vCenter Server Heartbeat in a WAN environment requires additional considerations. Each server
within the vCenter Server Heartbeat pair requires its own separate Principal (Public) IP address and a VMware
Channel IP address in a separate dedicated subnet.
Static IP address in a different subnet than the Principal (Public) network with a different IP address
than the Primary server channel NIC
Correct network mask
No Gateway IP address
No DNS IP address
NetBIOS enabled (disabled during the installation process)
File and print sharing enabled
WAN Requirements
When deploying vCenterServer Heartbeat in a WAN environment, the following components must be
configured:
N
OTE Prior to installing vCenter Server Heartbeat, verify that vCenter Update Manager and vCenter
Converter are configured using Fully Qualified Domain Names (FQDN) rather than IP addresses.
Persistent static routing configured for the channel connection(s) where routing is required
Two NICs (1 x Public; 1 x Channel) recommended
At least one Domain Controller at the Disaster Recovery (DR) site
If the Primary and DR site use the same subnet:
During install, follow the steps for a LAN or VLAN on the same subnet
Both servers in the vCenter Server Heartbeat pair use the same Public IP address
If the Primary and DR site use different subnets:
During install, follow the steps for a WAN
Both servers in the vCenter Server Heartbeat pair require a separate Principal (Public) IP address and
a VMware Channel IP address in a separate dedicated subnet
Provide a user account with rights to update DNS using the DNSUpdate utility provided as a
component of vCenter Server Heartbeat when prompted during the setup process
Recommend integrating Microsoft DNS into AD so that DNSUpdate can identify all DNS Servers
that require updating
At least one Domain Controller at the DR site
Refer to the following articles in the knowledge base:
KB 1008571 – Configuring DNS in a WAN Environment
KB 1008605 – Configuring vCenter Server Heartbeat to Update BIND9 DNS Servers Deployed in a
WA N
16 VMware, Inc.
Bandwidth
Determine the available bandwidth and estimate the volume of data throughput to determine acceptable
latency for the throughput. Available bandwidth can affect the required queue size to accommodate the
estimated volume of data. VMware recommends making a minimum of 1Mbit of spare bandwidth available
to vCenter Server Heartbeat.
vCenter Server Heartbeat includes a Low Bandwidth Module for use in WAN environments. When enabled,
the VMware Channel compresses the data, optimizing the traffic for low bandwidth connections causing some
additional CPU load on the active server.
Latency
Latency has a direct effect on data throughput. Latency on the link must not fall below the standard defined
for a T1 connection.
Installation Process
After selecting implementation options, begin the installation process. The installation process for all scenarios
follows the same basic procedure.

“Verifying vCenter Server Heartbeat” on page 21
“Exercise One” on page 21
“Exercise Two” on page 22
“Exercise Three” on page 23
Verifying vCenter Server Heartbeat
The Installation Verification process validates the installation and tests the software operation.
The following exercises are examples and must be performed in order. VMware does not recommend
attempting to test a failover on a properly operating server pair using methods such as unplugging a power
cord. When power is lost, any data not written to the passive server is lost. VMware recommends that a
switchover rather than a failover be used to test the operation of the passive server.
Exercise One
This exercise demonstrates that the Secondary server can function as the Primary Server without the test data
being immediately replicated back to the original server. During the exercise, stop the Primary server from
providing service and hide it from the network, then introduce the Secondary to the network and allow it to
provide service.

Exercise Two
This exercise follows Exercise One. The objective is to take a working active server (Secondary) and
synchronize it with the passive (Primary). This exercise also demonstrates that all the correct services stopped
when the Primary server became passive.
Starting Conditions
vCenter Server Heartbeat is running on the Secondary Server, which is active. vCenter Server Heartbeat is not
running on the Primary server and is set to passive without starting vCenter Server Heartbeat.
