Exchange 2010 comes, just like previous versions, in two flavours; Standard and Enterprise. There is just one single product, but the serial key you enter will determine the version. As long as you are running in trial mode, the installation is an Enterprise version. Although the pricing is not yet available, traditionally the Enterprise Edition is about 4 times the price of the Standard Edition.

First thing we see is that the Standard Edition is limited to 5 databases per server. The Enterprise Edition scales up to 100 databases per server. Based on the beta documentation, it looks like DAG is available in the Standard and in the Enterprise Edition.

But you have to remember that DAG requires some Windows clustering components, only available in Windows Server 2008 Enterprise Edition. (And this edition again is about 4 times the price of the Standard Edition.)

Well, the question really is: With Exchange 2010 Std version, is it possible to run it in a cluster or do i need the Entreprise Version to do so?

For my guess so far,
the answer is, yes you can install exchange 2010 std on a cluster  (why not)

but do it able to failover? i am not sure. some say YES, it will, with 2 database only, but some say NO, where only the enterprise licence come with failover function...

there is no definite answer until later stage ..

For sure, Standard edition of Exchange 2010 wouldn't support DAG. Thus, you have to opt for the Enterprise edition. Because DAGs rely on Windows Failover Clustering, they can only be created on Exchange 2010 Enterprise Edition Mailbox servers that are running Windows Server 2008 Enterprise or Windows Server 2008 Datacenter.

Hello,

Yes, DAG is supported in Exchange 2010 standard edtion but it requires some clustering component which are awalable in windows 2008 enterprise edition so you will defenately need that, so to answer your original question: Yes, you can run exchange 2010 in a cluster on windows 2008 ent edition.
