Always situations and exact use cases pose the solutions to be applied, sure i agree.
Well, in my opinion after reading some docs and pptx, it has never been pretty clear the purposes and differences between the two methods.
This is a MCC IP scenario bid w 4-node (2localHApair +2remoteHApair nodes-controllers).
In the beginning this will be a active-passive MC layout , 2 data aggregates in sync in localHApair. Nothing complicated. A database host-server in local frontend and another similar waiting in remote to grab and activate the SVM+luns+iSCSI sessions in case of disaster in local site. Spanned network layer2 among sites in frontend access.
My specific situations in order to select one MCTB or Mediator for Automatic Unplanned events, are:
-Storage only disaster
I like Mediator because it avoids switching over if that DR mirroring and plex mirrors are not in sync.
