setting up dbs in exchange 2010 DAG

I just want to confirm that I am setting up the actual drive sizes for dbs in a DAG setup, for exchange 2010 the correct way???

There will be 2 members of the DAG (2 mailbox servers) with a total of about 80DBS.(80 company locations) We will be putting half on one member of the DAG and the other half on the other member. Now with that being said, I don't want any DB to be larger than 250GB, per location.
So should I create  like 1TB disk sizes on each exch server and then put a certain number of dbs from each location under each 1TB disk?

Obviously we would have to monitor each locations DBS from here on out to make sure they do not go over say like 200GB

Depending on the version of Exchange you are running Standard or Enterprise will make or break your design. If you are using Exchange Standard 2010 you are allowed up to 5 mailbox database per Mailbox database server. If you are using Exchange Enterprise you will have up to 100 database per mailbox database server.

As for your drive requirements you can use the Mailbox Sizing Calculator to assist with this.

If you are using Enterprise then you will be fine. Just make note that when you have passive copies on your DAG members this accounts for actual databases.

So you have 2 DAG members 80 mailbox database across both server (40 on each). If one of your mailbox servers fails you are then running all 80 mailboxes on 1 server which is still under a 100, so you are good there. As for provisioning mailbox data drive sizes this becomes a guessing game as you are the only one that knows how much mail you get on an average day. Doing some sort of bench marking would be a good start.

Ultimately if you are looking to completely keep this under 250GB per database then I would encourage you to do some sort of Archiving, either using Exchange 2010 Archiving or a 3rd party like Symantec Enterprise Vault.

Do your monitoring and use the Exchange Sizing Calculator to get the base estimated guess for your setup.

Will,
I have one more question in response to your response above,,
If there will be 80 total dbs 40 on each of the 2 mailbox servers, would it be ok to just have 2 mailbox servers in the DAG since each will have 80 dbs counting the passive copies also?
Like will this make any kind of performance issue with just the 2 Mailbox servers?
