My client has a onsite Exchange 2010 server on virtual enterprise R2 2008 with Standard exchange. Currently they have DC on a data centre - however it is configured on a same site and same subnet - so logically it is the same AD site. My clients wants a possible DAG in the data centre (on the same subnet).
Can someone confirm what additional license I need for this set-up? Will an additional standard exchange license will do? They have 4 active exchange DBs on the onsite server. My guess is second license can cover 4 passive database
Thanks in advance
