Q. What are VMware's configuration recommendations for vCenter Server and Client based on environment size?

A. You might not think that vCenter Server and Client require much in the way of powerful hardware, but they can. To ensure your vCenter infrastructure performs well, you need to use powerful enough hardware to run vCenter Server. Very large environments will also need greater power for the vCenter Client.

As found in the VMware vSphere Upgrade Guide, the following are VMware's recommendations for the number of processing cores, memory, and available disk that both vCenter Server and Client will need for adequate performance:

Up to 50 Hosts and 500 Powered-On VMs

Product                        Cores               Memory                      Disk

vCenter Server            2                      4GB                             5GB

vSphere Client            1                      200MB                        1.5GB

 

Up to 300 Hosts and 3,000 Powered-On VMs

Product                        Cores               Memory                      Disk

vCenter Server            4                      8GB                             10GB

vSphere Client            1                      500MB                        1.5GB

 

Up to 1,000 Hosts and 10,000 Powered-On VMs

Product                        Cores               Memory                      Disk

vCenter Server            8                      16GB                           10GB

vSphere Client            2                      500MB                        1.5GB
