Software Requirements
You can deploy vMA on the following systems:
You can deploy vMA by using a vSphere Client connected to an ESXi host or by using a vSphere Client connected to vCenter Server 5.5, vCenter Server 5.1 or later, vCenter Server 5.0 or later.
You can use vMA to target vSphere 5.5, vSphere 5.1 and later, and vSphere 5.0 and later systems.
At runtime, the number of targets a single vMA instance can support depends on how it is used.
