Why only two ZK machines? Normally it is recommended to have 3 or 5. The ZK load here should be very light so you might rather collocate ZK with other services a bit more. Is there any reason not to use 2T drives all round? My own tendency would be to put 12GB all round so that all machines are interchangeable.
