Exchange 2010 Standard Maximum DB Limits

    Question

  • Can anyone give me the link that officially states what the maximum size of any one database can be for Exchange 2010 Standard edition can be?  I can only find out what to do to increase the limit from the 50GB default.  But no where can I find what is the maximum size?  This is very frustrating considering this should be a very common question and one that should be very easy to find.  I would of guessed they would tell you the limit on the page that describes how to change the limit, but no, that would make too much sense.  Anyway, I need something from MS website that states this officially in order to make sure I'm correct in what I tell the customers.  What I have found is the limit is 16TB, but, I've seen 1TB as well.  I think the limit in 2007 was 200GB, so to go from 200GB to 16TB limit on Standard edition would seem quite extreme in my opinion.

    Thanks!

    • ~16TB is supported.
    • But keeping the database to 2TB maximum is recommended and best practice if you have DAG/HA implemented. 
    • Without DAG, it is recommended to keep @ 100GB.
    You can refer below guidance for further information which is not limited any edition, but common for both...

    Hope this will clear the confusion...

  • The default database size limit in Exchange 2010 Standard Edition is 50GB.
    There is no default database size limit for the Exchange 2010 Enterprise Edition.
    You can change these values using regedit.
    Note: this will be dependent also on the hardware of the server. A small tip here to use the exchange calculator

    Ok, that link helps a little, but very unclear in it's delivery.  I don't understand why this is such a difficult thing to find and why they don't put that info on the link that states how to increase the size.  Anyway, thanks for the info and this confirms what I needed to know.

    Elie, thanks for the try but you may not have read my post completely or understood it.  The things you stated here are what I said I could find, but nothing that gives the actual limit, not the default limits.  The link you sent me to was the exact one I'm referring to that DOES NOT give you the information I asked in my original post.

    The answer is 16TB, and then there are recommended sizes and other information which Amit was able to provide.

  • Jesus, I just have to reply to this because you people are retarded and cannot seem to understand the question the guy is asking.  Perhaps you need to slow down a little when you're reading the question instead of assuming you already know what is being asked.  The question is:

    How do I verify the current max size setting as it's currently applied?

    Get it?

    Ok, so I know how to set the size via the registry.  We know what the default size is.  I've set it via the registry.  How do I verify that the setting has taken effect?

    My registry is already set to 100GB.

    I cannot find any documentation that states if the registry entry should be 32 bit or 64.  Furthermore, do you have to restart the server for this to take effect?  Why is the documentation on this subject so poor?

    He already knows how to up the default limit on the machine himself.

    As he says...

    Can anyone give me the link that officially states what the maximum size of any one database can be for Exchange 2010 Standard edition can be?

    And...

    But no where can I find what is the maximum size?

  • Now this is realy odd .... The article does in fact mention 1024 bg ...

    I'm currently reading the Configuring Microsoft Exchange Server 2010 Training Kit and on page 54, it says "The default db size limit for Exch 2010 Std Ed is 50 gb !!!

    Now I really hope they don't have this question on the exam ....
