This section describes the active/active solution design that we implemented by using a Cloud Foundation on a VxRail multisite stretched-cluster deployment configuration with PowerMax SRDF/Metro. This design provides enhanced levels of flexibility and availability that extend the core capabilities of the cloud platform. The VMware Cloud Foundation on VxRail solution natively supports a stretched-cluster configuration for the management domain and a VI workload domain between two availability zones by using vSAN stretched clusters. A PowerMax SRDF/Metro with vMSC configuration is added to protect VI workload domain workloads by using supplementary storage for the workloads that are running on them.
Two types of vMSC configuration are verified with stretched Cloud Foundation on VxRail: uniform and nonuniform.
The following figure shows the topology of the Cloud Foundation on VxRail uniform stretched-cluster configuration with PowerMax SRDF/Metro.

The following figure shows the topology of the Cloud Foundation on VxRail nonuniform stretched-cluster configuration with PowerMax SRDF/Metro:
