When you deploy the vCenter Server Appliance, you can select to deploy an appliance that is suitable for the size of your vSphere environment. The option that you select determines the number of CPUs and the amount of memory for the appliance. The size of the Platform Services Controller appliance is the same for all environment sizes.
Hardware Requirements for the vCenter Server Appliance
The hardware requirements for a vCenter Server Appliance depend on the size of your vSphere inventory.
| Number of vCPUs | Memory | |
|---|---|---|
| Tiny environment (up to 10 hosts or 100 virtual machines) | 2 | 10 GB |
| Small environment (up to 100 hosts or 1,000 virtual machines) | 4 | 16 GB |
| Medium environment (up to 400 hosts or 4,000 virtual machine) | 8 | 24 GB |
| Large environment (up to 1,000 hosts or 10,000 virtual machines) | 16 | 32 GB |
| X-Large environment (up to 2,000 hosts or 35,000 virtual machines) | 24 | 48 GB |
Note: If you want to add an
ESXi host with more than 512 LUNs and 2,048 paths to the
vCenter Server Appliance inventory, you must deploy a
vCenter Server Appliance for a large or x-large environment.
Hardware Requirements for the Platform Services Controller Appliance
The hardware requirements for an external Platform Services Controller appliance are 2 vCPUs and 4 GB memory.
