vCloud Director 1.5 and stretched cluster architectures (2009651)
This article provides common use cases for implementing vCloud Director 1.5 in conjunction with stretched cluster architectures and defines the supportability of these configurations.
Stretched clusters consist of two or more physical ESXi hosts deployed in separate sites that are less than 100 kilometers apart and are contained within a single vSphere cluster. VMware supports specific stretched cluster configurations for a vSphere environment. As vCloud Director leverages a vSphere environment to provide resources for a self-provisioning, multi-tenant cloud solution, it, in turn, supports the use of any supported vSphere configurations, including stretched clusters.
The use cases for utilizing stretched clusters with vCloud Director can be divided into two categories: workload mobility and disaster avoidance.
To setup a stretched cluster, ensure that all vSphere requirements are met. Also, ensure that the storage array to be used in the stretched cluster configuration is supported. For more information, see the Hardware Compatibility Guide.
