I run my HomeLAB with a intel NUC with one interface at all (not official supported). A vMC comes standard with 3 virtual nics on the VM side and can all connect to the same vSwitch if you want.
Please follow the installation guide
https://support.arubanetworks.com/Documentation/tabid/77/DMXModule/512/Default.aspx?EntryId=32542
Focus here on the mimimum hardware and hypervisors requirements. vSphere Hypervisor 5.1, 5.5, 6.0, or 6.5 are supported (mine HomeLAB works fine on 6.7 but also not offical supported)
Hyper-V Version Windows Server 2012 R2 Hyper-V and 2016 are also supported as hypervisor.
Aruba recommends using Intel Xeon E5-2670 v3 @ 2.3GHz enterprise grade CPUs for optimum performance.
MC-150-VA required 5vCPU, 8Gb ram, 8Gb ramdisk for example. see the installation guide ;).
