Many thanks for that.

Now - our DSS is used for 2 purposes. Firstly a Datastore for all of our companies files and secondly it is the Datastore for our 3 ESX servers (their harddrives).

The volumes for the file servers are seperate from the volumes for the VM drives which will make things easier.

Do you have an idea of how I can attach the Shares to the ESX? So far I have not seen a 'username/password' entry when I do the attachments via VSphere

Again many thanks for all of your advice.
Dave
