Nothing special to thing about for vmware though.
Actually VMware has a limit of 1024 paths per host so you do have to consider that. We had to change our exchange 2013 disk layout to minimize the number of paths used as we already had ~800 paths already in use and we were rolling out 3 servers with a dozen databases and a dozen archives which would have put us over 1024 if we had done one one lun per database/archive like we did for 2010 (24*3*8 paths per lun).
Which is why I said it depends on the number of hosts....
Nope, it's per host, not per cluster so if you have a host with lots of data stores you can reach the limit with just one host.
