What is VMware vCenter Server?
vCenter Server: A Key Infrastructure Component
A universal hub for virtualization management
How Do You Use vCenter Server?
Monitor cluster, host and VM performance
Manage VM and host provisioning
Patch and update hosts and VMs
Configure and operate VMotion, DRS and HA
Provision and manage a VDI environment
Manage disaster recover plans
Impact of vCenter Server Downtime
Component

Virtual Machines
Management requires direct connections to host;
can’t provision new VMs from templates

Agenda
Why is VMware vCenter Availability Important?
What Needs to be Protected?
Protecting vCenter Server with vCenter Server Heartbeat
Determining a Strategy
Define the Scope of Protection Desired
Which is most important?
Local high availability for hardware/network failures?
Protecting application integrity and uptime against all types of
threats?
Remote disaster recovery for large scale, site-wide outages?
What is the recovery time objective?
Need to base this on what functionality is unavailable during vCenter
Server outage

What is required to restore vCenter functionality?
vCenter Server is an almost stateless application
Data stored in the vCenter database is the most critical resource
Following data is necessary to restore the vCenter functionality
(with intact database)
vCenter server IP Address
DNS name for ODBC connection
License files for the License Manager Server
Security Certificates
vCenter Configuration file
vCenter Plug-in data
Customized data from upgrade directory (if applicable)
Cold Standby Recovery Procedure: Simple, Slow
Maintain separate
up to date copy of
local configuration
files
ESX Server hosts
reconnect
automatically

Able to assign
primary’s IP to
standby?
no
Done
Run script to reconnect

Warm Standby Recovery Procedure: Complex, Faster
Keep local

However, several options can be used to mitigate the potential
for vCenter Server downtime
The solution of choice will depend on level of protection desired
and recovery point objectives.

Summary: Why vCenter Server Heartbeat?
 High availability for VC is growing in importance for
customers running VMware in production
Underlying infrastructure needs to be fully protected
HA provides robust general-purpose protection of virtualized
workloads
Need to protect against configuration errors, network failures, OS
failures, database failures with WAN failover support
Many customers run vCenter Server on a physical server
Other solutions are expensive, complex and lack app awareness,
support for database, WAN failover
Customers have been asking for a VMware solution that
provides more granular availability for vCenter Server
Introducing VMware vCenter Server Heartbeat
Extends availability for the vCenter Server platform
Announce at VMworld Europe, GA in mid-March
Add-on to vCenter Server protects critical components of the
infrastructure
Deep awareness of the vCenter Server components
Failover of the application and database over the LAN or WAN

Best-of breed-technology
VMware has signed an agreement to license the technology for
Heartbeat and sell it as a VMware product
Proven technology supports SQL, Exchange, Blackberry availability
VMware will provide training and support as with any other VMware
product
Neverfail provides underlying technology and updates, as well as
support for field, channel and GSS enablement

vCenter with VMware HA: Out-of-Band
Two approaches

Two vCenter instances manage
each other (pictured)
Both run in HA cluster
Each manages the other’s HA
cluster
vpxd
Separate vCenter instance is
used to manage 2-node HA
cluster (not pictured)
vCenter with VMware HA: In-Band
vpxd
vCenter Server manages the
VMware HA cluster providing
its protection
When the ESX hosts with
vCenter VM fails, VM is
restarted automatically by HA
Failover functionality provided
by HA is independent from
vCenter (post-configuration)
