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 performanceManage VM and host provisioningPatch and update hosts and VMsConfigure and operate VMotion, DRS and HAProvision and manage a VDI environmentManage disaster recover plans

Impact of vCenter Server Downtime

Component Impact Experienced

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

ESX Servers Management requires direct connections to host

Performance & Monitoring Statistics

Historical records will have gaps during outages, still available via ESX Servers

VMotion / Storage VMotion Unavailable

VMware DRS Unavailable

vCenter Plug - Ins Unavailable

VMware HA HA failover works, admission control unavailable

VMware VDI Cannot provision new desktop instances

Why is VMware vCenter Availability Important?What Needs to be Protected?Protecting vCenter Server with vCenter Server Heartbeat

Agenda

Determining a Strategy

Define the Scope of Protection DesiredWhich 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

How Do You Protect vCenter Server Today?

• No protection• Keep a backup copy archived• Cold standby• Clustering• VMware HA

What is required to restore vCenter functionality?

vCenter Server is an almost stateless applicationData stored in the vCenter database is the most critical resourceFollowing data is necessary to restore the vCenter functionality

Protecting vCenter Server Against Downtime Threats

VMware HA

Linked Mode provides visibility across multiple vCenter Servers (coming in

2009)

VMware HA protects a virtualized vCenter Server against hardware

and OS downtime

Heartbeat provides broad failover protection for vCenter Server against all types of planned or

unplanned downtime

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 protectedHA provides robust general-purpose protection of virtualized workloadsNeed to protect against configuration errors, network failures, OS failures, database failures with WAN failover supportMany customers run vCenter Server on a physical serverOther solutions are expensive, complex and lack app awareness, support for database, WAN failoverCustomers have been asking for a VMware solution that provides more granular availability for vCenter Server
