Best Practice
- Remove the Administrators group from the VMWare vCenter Administrators roles and configure proper delegated administration model.
- There is no virtual NIC traunking between ESH standard switches, communcations is conduct via the physical link
- Develop naming convention for VMware objects (Switchs,etc)
- Sphere vCenter, Loosing this will effectivtly mean that the advanced feature set of the Enterprise Plus wont be avaiable until Sphere vCenter is restored. To migitate this ricks you can use Clustering, Backup System and vVMware vCenter Headbeat Server
- The Database will also require Backup configured and aslo Replication or Clustering
