I'm pretty new to vm machines I have some general questions:
1st I have a machine with 16 gigs of ram in it and about 600 gigs of space.  How many VMs can I get on there.  I'm thinking a max of 4 (if each machine has 4 gigs of ram)?
If I have 4 machines for example do I need 4 different Nic cards - one for each Virtual Machine?
If necessary can I attach a SAN or NAS to one of the VMs?

You can attach a SAN or NAS to a VM via the network.

yes it depends on the config of the vms really but as your using VMware the network inside can effective load balance the nics inside the network vswitch so you don't need to worry about a nic per vm just add the vms to the vswitch

you can add a san or nas easily to VMware just google it and you will find its relatively easy

If I use a NAS or SAN ISCSI too?  Or does that need to be attached to the hardware and then installed in the VM?

Best utilisation is to connect to ESXi host hardware.

But you will see more benefits if you have two or more hosts and licenses for VMware.

OK that's great one more question... If i may... If I have say for example 1 VS working nothing else yet.  If I want to add lets say a data drive is there a way to "steal" space from ESX server?
