Exchange 2013 - max db size using 3 node DAG

Question

Hello!

I couldn't find a straight forward answer anywhere so i have to ask here.
We have a 3 node DAG. Everything is fine except the mailbox db size. I have only one database that is 850gb (size on disk 915gb). What is the maximum database size according to MS on a dag? The exchange license is Standard.

Thank you in advance

Hi there.
5 is the max and yes you can do that.

Answer 2

Thank you so much Andy! You are a star :)

Answer 3

So for example if i have one db to 3 different mailbox servers as active/passive/passive that doesn't count as 3 db's but one... Am i correct?

Answer 4

How many databases i can have mounted with a standard license? Maybe instead of buying enterprise license i can create a new database and move half of the users there...

Answer 5

If you are using standard, the max is 1024GB
