Exchange Server 2007 fault tolerance and clustering

You can not achieve fault tolerance with only 2 servers. clustering available with mailbox role, others are load balancing.

read through this.

High Availability is explained here.

If you are worried about the DR(Disaster recovery), then the procedures are different.

Hope this helps to move forward.

The first link is about whitelists...am I missing something?  Just reading through the second now....

That's a document I had seen before; what I'm after is some real advice as to move forward rather than links to convoluted M$ docs.  Thanks.

Oh sorry, that was a wrong one.. I was helping on an issue..

the right one is here.http://technet.microsoft.com/en-us/library/bb267003(EXCHG.80).aspx

my sincere apologies.

As I told you, it is again upon your requirement. You can not achieve fault tolerance with only 2 servers. You need at least 4 servers, 2 for HUB/CAS role and 2 for mailbox role cluster,(not counting the AD servers) to do the fault tolerance in exchange 2007 and above.

Since  you asked the question which is hard to put in few words, you will really have to go though design considerations.. Dont thing there can be any short cuts other than reading the executing..

Shame, I'm a shortcuts kinda guy!  Thanks Praveen, I'm reading the docs now.

See Exchange deployment options diagram i have attached....
Deployment-Options.pdf

@ProtechCT- I think -Juddy- looking for Ex 2007, not for Ex 2010 which you have pasted above.

I would be happy if Juddy go for 2010 now if for new implementation, that got plenty of features...

So if I upgraded to 2010 I would have more options available? Tell me more...

Yes sorry the diagram i posted, it is related to Exchange 2010, as you can see lets you setup DAGS giving you the fault tolerence you were looking for.

Thanks for the heads-up PraveenBalan

Great, thanks.
