Is this brand new setup or are you going to re-use what’s on the existing disk drives ? If this is a brand new setup, then go eager zeroed. If you have a database already behind SAN on an existing LUN, I’d go RDM, as you would not need to do any migration, and by using RDM just plug an existing LUN in. But judging from your description you aim to have 1 ESX host using internal drives, so go eager zeroed DS. I am not sure I understand the remark about a need to add disks as ‘raw’ since they are internal. You can put a datastore onto an internal drive. RDM’s advantage is a) re-use of an existing data (behind an existing LUN), b) whatever backup/snapshot techniques were used on SAN for that LUN(s) can still carry on unchanged You can technically use RDM for local drives with some tweaking, but there will be no benefit at all, only extra work. Ø Mainly it is going to be one physical server Question tho – what are you going to do if this one server bursts up in the flames ? You should at least have 2 hosts and use HA. shameless plugs
