Workload Mobility Across Data Centers with Innovations from VMware, Cisco, and EMC


Application Mobility for Business Continuance

Application mobility: Transfer application workloads/virtual machines between data centers, with no service interruption

Business continuance use cases:

Presentation Notes

LDVM allows IT administrators to move application servers between distant hosts without service interruption. It has been identified as appropriate for use cases that require applications to remain active and to maintain state/connections while being moved over distance. It is a planned process that is completed over a period of time. Capacity management. Cases in which application load is transferred between data centers for purposes of capacity management. 2) Disaster avoidance. In the event that a service-impacting event might be identified before it occurs, application workload might be transferred to an un-impacted data center. 3) Workload redistribution. Application workload might be brought up and configured at one data center then ultimately transferred (uninterrupted) to another as part of the provisioning process. 4) Data center upgrades. When upgrading infrastructure at one data center it may make sense to transfer application workload to another data center without interruption.


Best Practices

VMotion 5 msec roundtrip latency between ESX hosts

≥ 622 Mbps of WAN bandwidth

Source/destination ESX on the same IP subnet and broadcast domain

Storage High availability to VMs in both data centers Acceptable application SLAs

Network LAN extensions across WAN

High availability–Spanning tree isolation, network loop prevention

Load balancing–Full use of WAN bandwidth

Scalability–Move multiple virtual machines

Routing Optimization–Reach VMs in current data center site

Visibility and Granularity at VM Level–End-to-end consistency across QoS, security, provisioning, and traffic visibility
