Hello,   So what I've found so far is that without the enitire environment under single vendor,  it won't be possible to do a recovery later with any assurances that it won't cause problems.   They also indicated that the node that's the active node for the DB can change.  
Hi,  I just wanted confirmation that, according to this post [URL] it is not possible to use Microsoft HIT on Exchange DAG if one or more servers is not connected to the Equallogic storage.  Wasn't sure if anything might have changed since that post...
Servers in DAG not using Equallogic storage - HIT unsupported?
