vFabric Standard and vFabric Advanced packages are licensed on a per-VM and average-usage basis, exclusively for virtual and cloud environments.
Each licensed VM can run any or all vFabric software components. Thus licensing is tied to VMs, rather than to component installations. One license unit covers one virtual machine with a maximum of two VCPUs. For example, if you plan to install one or more components on one VM with four VCPUs, you need two license units for that VM.
You obtain a pool of licenses that you activate by adding only one license key to vCenter Server through the vSphere client. Rather than installing a license key on each VM, you register one license key with vCenter that represents the number of license units that you have purchased. See Activate vFabric Platform Licenses.
To check the validity of a license key, see Using the vFabric License Check Tool.
The production license is a V8 license that is perpetual for a particular version and package of vFabric 5. If you do not install a license, your component installation defaults to an evaluation license, which is valid for 60 days after you first start the component.
