4. What is VMware vCenter Server?

5. vCenter Server: A Key Infrastructure Component A universal hub for virtualization management

6. 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

7. Impact of vCenter Server Downtime ComponentImpact Experienced Virtual Machines Management requires direct connections to host; can’t provision new VMs from templates ESX ServersManagement requires direct connections to host Performance & Monitoring Statistics Historical records will have gaps during outages, still available via ESX Servers VMotion / Storage VMotionUnavailable VMware DRSUnavailable vCenter Plug - InsUnavailable VMware HAHA failover works, admission control unavailable VMware VDICannot provision new desktop instances

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

9. 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

10. How Do You Protect vCenter Server Today? No protection Keep a backup copy archived Cold standby Clustering VMware HA

11. Protecting vCenter Server vCenter ServerDatabase Server VI Services VI Inventory Database Server Standard DR Solution Standby vCenter Server Primary Replication of state files

12. 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)

13. Cold Standby Recovery Procedure: Simple, Slow Able to assign primary’s IP to standby? Maintain separate up to date copy of local configuration files Install fresh vCenter instance Install config files; connect to standby DB Disaster! ESX Server hosts reconnect automatically Run script to reconnect all ESX Server hosts Done yes no

14. Warm Standby Recovery Procedure: Complex, Faster Able to assign primary’s IP to standby? Keep local configuration files synchronized between primary and standby Disaster! ESX Server hosts reconnect automatically Run script to reconnect all ESX Server hosts Done yes no Faster end-to-end recovery (RTO) Also allows for scripting and automation Replication of configuration files through host-based replication or backup tools

24. 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
