Hi All,

After a successful ScaleIO POC with a Partner, during our conversation the partner had a couple of queries regarding upgrading the  present 3 MDM config to 5MDM config. The queries were :

1. Do the new MDM's need to be added as a Stand by MDM's ?

2. Since in a 5 MDM config 1 is Primary, 2 are Seconday and 2 Tie breakers , in case the Primary goes down, how is it decided that among the 2 Surviving Standby's who takes over as the primary and what role do the Tie breakers Play in this situation

3. In a hypothetical scenario where the primary MDM goes down, what happens if there is a split brain b/w the Surviving Seconday MDM's and the Tie breakers ( 1 Tie breaker can see only 1 Standby )

The 3rd Query from the partner raises this question inside me - Is this scenario really possible and if yes has anyone encountered this in their environment.

Thanks in Advance.
