We have 2 sites, one being HQ where all users are, and a DR site where no users reside.
On the DR site we have a set of servers doing DFS and DAG for backup purposes.
I know that in traditional DAG, a seperate replication network is best practise - the main reason I can think of is so replication traffic does not have to contend with other data.
In our VM Setup we do not really have capacity for installing any extra physical nics, therefore I was wondering what the pitfalls where of utilising other nics for this purpose.
In each of our servers we have 4 NICS - 2 for client facing data, 1 for VM Management traffic, and 1 for VMotion.
What kind of problems could we possible face by using the VMotion network, or the VM Management network?
