Guest virtual machines cannot be deployed in the Cloud Foundation management workload domain except under a consolidated architecture. At initial deployment of Cloud Foundation on VxRail, after the first VxRail cluster is built, Dell Technologies will deploy a temporary virtual appliance named ‘Cloud Foundation Cloud Builder’ on the cluster. This tool uses the deployment parameters captured during the planning and design phase, and layers the Cloud Foundation management workload domain on the VxRail cluster. In the same process, Cloud Builder deploys an initial core set of virtual machines to support Cloud Foundation on VxRail management.
This initial set of core virtual machines from Cloud Builder provides a baseline on the resources required to bring up the management workload domain and to begin deploying VI workload domains on a standard architecture. However, for each VI workload domain that is created, additional virtual machines for management purposes are deployed. Therefore, in order to get more accurate sizing guidelines for the management workload domain and VI workload domains, the planned use cases for the VI workload domains must be understood and captured. Then, a resource consumption assessment is completed for both the management workload domain and the VI workload domains, which are used to determine the required size of the underlying VxRail platform for all the planned domains.
The tables in Appendix A: Cloud Foundation on VxRail checklist can be used to provide estimates of the minimum sizing requirements for the management components, based on planned use cases.
