Here is another great article by MSExchange team touching base some of the mostly asked questions in Exchange 2010.
Simplifying and reducing the complexity of messaging environment while making it full redundant and faster is the most impressive part of Exchange 2010. You don't need to deploy Exchange in complicated SAN.
Use DAS ( direct attached storage ) and simplify the operations of Exchange by taking dedicated SAN personal out the picture and have your Exchange administrators to have full responsibility and control.
As you can read more from bottom link most of these improvement are targeted to lower the cost, simplify the application deployment and operations while providing the best messaging experience.
Some of the highlights from this article

Those of you who dealt with cluster exchange servers in the past or present will remember and know the word failover. The fail over most of the time in Exchange word alarms the Exchange administrator unless administrator is failing over for maintenance in the scheduled window.
Remember Clustering you have Exchange Server A , you have Exchange server B , and use Microsoft clustering technologies to create Virtual Server which points back to “Active node”. So the idea here is clients who are using mail services connecting to Virtual server ( Virtual Server is mapping to Active Server) all databases and logs are being kept on the SAN backend, so if Active server goes down or gives up from shared resources the passive server jumps in and tales over the shared cluster resources.
If you pull up one of the user properties in Clustered Exchange environment, you will easily see the Exchange server is pointing to CMS server name which maps to Active server. IF Active server fails down the CMS is being taken over by passive node which becomes active and since clients are able to locate the CMS server, by using second server they access Exchange databases logs etc.
Here is the user who’s mailbox is configured on DAG
If you take look at this picture you will quickly see , “DB1” has two copies on two different server and if MAIL3 ( server) goes down the AD ( Active manager) will activate the same database on the Different server and users will still get connected.
The goal is to provide continuity to Exchange clients and keep them happy. Understanding how cluster works can easily be complicated to be honest, if you have never worked and not set it up by nature you may thing it sounds complicated and I hear you.
So what has been Changed in Exchange 2010?, beside Exchange 2010 is the fastest, greatest messaging application it is offering perfection and simplify in my opinion and you will understand more and appreciate this when you move into E210 (-:, trust me this isn’t advertisement it is a “FACT”.
What is DAG?
Active Manager
*** setting up DAG is fairly easy to be honest, you will love the little steps and intelligent automation behind DAG once you start implementing it***

One of the most frequent asked question on the Exchange forums is to load balance CAS servers. I think the excitements of Exchange being redundant ( DAG) as nature bringing all these good questions and scenarios on the table.
I have learned recently great information in this regard and wanted to pass it on to you guys to clear some of the confusion may exist.
Question:
Can TMG/ISA be used to load balance the CAS servers ?
Answer:
ISA or TMG cannot load balance RPC traffic it can only load balance Internet protocol traffic )-: ( HTTPS,OA)
So as summary
| WNLB with HT/CAS | Possible but not recommended | Network flooding & lack of service awareness Scalability |
| WNLB MBX+CAS | Not Possible!!! | limitation build into Windows (hard-blocked) |
| ISA /TMG | Cannot load balance RPC traffic | Only internet protocol traffic,such as HTTPS,OA |
As I learn more in this matter I will come back and update this information.
