Windows Server 2008 R2 Standard?

I am installing Windows 2008 Srv STD R2 OS for Exchange DAG mailboxes.  Are there any limitations for STD edition or should I go with Enterprise?

Thanks.

yes, he means that. enterprise is still needed but you can install exchange server before installing the cluster components...

So for Windows STD should be OK.  No windows cluster.  But Exchange DAG.

Actually DAG is relay on windows cluster services.... so it is only available on windows server enterprise editions..

Sorry, you are right...

but,still DAG require enterprise edition. here is the explanation :
http://www.exchange-genie.com/2009/04/database-availability-group-dag-exchange-2010/

"Here comes the DAG
So now it’s time to forget everything that I just mentioned previously in this article about Exchange clustering.
What has been removed?
No more EVS/CMS
Database is no longer associated to a Server but is an Org Level resource
There is no longer a requirement to choose Cluster or Non Cluster at installation, an Exchange 2010 server can move in and out of a DAG as needed
The limitation of only hosting the mailbox role on a clustered Exchange server
Storage Groups have been removed from Exchange
Is anything the same?
1. Window Enterprise Edition is still required since a DAG still uses pieces of Windows Failover Clustering
What’s New?
 1. Other roles can be install on the mailbox server when it is a member of a DAG
2. A database name must be unique in the Exchange Org "

I found this statement on http://www.msexchange.org/articles_tutorials/exchange-server-2010/high-availability-recovery/uncovering-exchange-2010-database-availability-groups-dags-part1.html

Incremental deployment - Because DAGs still use some of the WFC components such as the cluster database, heartbeat and file share witness functionality, Windows Server 2008 SP2 or R2 Enterprise edition is required in order to be able to configure Exchange 2010 Mailbox servers in a DAG. But Exchange 2010 supports an incremental deployment approach meaning that you don’t need to form a cluster prior to installing Exchange 2010. You can install the Exchange 2010 Mailbox servers, and then create a DAG and add the servers and any databases to the DAG when needed.

Does it need I still need a cluster and still need to have an Enterprise Edition for W2K8?
