6.7

Before you deploy the appliance, synchronize the clocks of the target server and all vCenter Server and
Platform Services Controller instances on the vSphere network. Unsynchronized clocks might result in
authentication problems and can cause the installation to fail or prevent the appliance services from
starting. See Synchronizing Clocks on the vSphere Network.
Hardware Requirements for the vCenter Server Appliance and
Platform Services Controller Appliance
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.
Table 2‑1. Hardware Requirements for a vCenter Server Appliance with an Embedded or
External Platform Services Controller
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

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 a Platform Services Controller appliance are 2 vCPUs and 4 GB memory.
