Nested esxi lab - design thoughts

I will create a lab with 2 sites, one site using VMware Workstation on my laptop and the other will be a physical ESXi host.

In each, we will create nested ESXi v5.5 hosts.

The objectives of this lab are:

1) practice for VCAP-DCA
2) learn and test vSphere replication and SRM
3) learn and test vCops

We will also work with

Active Directory - one ADDC for each site, running in the nested ESXis
iSCSI on the main site with Openfiler running on a VM at the same level as the nested ESXis
NFS on the backup site, with TBD running on a VM at the same level as the nested ESXis

One vcenter will be the appliance and another the windows version, running on the nested ESXis

The hardware we have:

both i7
both 32 gb ram
both have one SSD and one hard disk
communicating over a home wireless 802.11ac (not exactly gigabit, but this simulates commercial WAN links fairly decently)

All will run on temporary licenses.
