Determining the vCenter system requirements

The minimum system requirements for the vCenter Server service are two CPUs of 2.0 GHz or faster and 4 GB of memory. When other services are installed on the vCenter Server or in larger environments, these minimum requirements may not provide the resources necessary to support vCenter deployment.

The size of the vCenter inventory, the number of hosts, and the number of virtual machines also have an impact on the amount of CPU and memory resources required. The minimum system requirements will support a small deployment of up to five hosts and 50 virtual machines.

How to do it…

The following steps will help you to determine the vCenter system requirements:

  1. Estimate the number of host and virtual machines that will be managed by the vCenter Server.

  2. Determine whether all the vCenter Server components will be installed on a single server or on separate servers.

  3. Size the vCenter Server to support the managed inventory.

How it works…
