How can I manage Dell workstations with OpenManage Essentials ?

First, is it possible? Because iv read that only Dell servers can be managed with OME.

I would like to inventory each Dell workstations I have in my environment, and be able to see their service tag with warranty expiration, etc.

Or which product must I use to do this? There are so much Dell management products like OMCI, OMCC, ITA, etc!! I am so lost with all these products.
