Exchange calculator 2013 / Using multiple databases on a single volume

Hi!

I’m currently trying to design a 2 DAGs solution for a customer with 4 copies, on 2 datacenters.

I would like to apply best practices here and use 4 databases on each JBOD disks.

However, I’m unable to set the sizer to get a 4 db/volume configuration if I use the Active/Active (Multiple DAG) setting.

Only way to get this result is to increase the number of servers.

However, this is OK if I use the Active/Active (single DAG) option.

Am I wrong somewhere ?

Thanks for your help! Have a great day !
