Hi ever1 there... To my curiosity i just want to experience with real time setup of exchange 2010. Actually i got brand new HP servers for some other purpose but for time being just want to use for test purpose i want to install exchange 2010 on hyper-V. I Need the setup as given below. Hyper-V R2 Host-1 Guest VM's Global Catalog/Active Directory Server Exchange 2010 HUB/CAS/MBX in DAG (All roles in one VM) Hyper-V R2 Host-2 Guest VM's Global Catalog/Active Directory Server (Redundancy) Exchange 2010 HUB/CAS/MBX in DAG ((All roles in one VM) My servers has 24GB Ram and 8x300 GB SAS HDD and Hardware Raid Controller Before Installing Hyper-V 2008 R2, shall apply Raid1 for two HDD's and Raid10 for remaining HDD's...really confused... Thanx in advance... Khan

Do you have a question? Be aware that with your proposed set-up you won't be able to use Network Load Balancing for fault tolerance on the Client Access and Hub Transport functions. You can't combine failover clustering, components of which are used for the DAG, with NLB on the same servers. Since you're virtualizing, you might consider separating the Mailbox role from the Hub Transport and Client Access roles on each.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Thanx for reply...My concern is Before i start installing Hyper-V Server, should i apply Raid1 for by taking two HDD's and Raid10 for remaing HDD's?

I can't answer that in a short-answer forum like this. I suggest that you model your requirements using the Exchange 2010 Mailbox Server Role Storage Calculator. http://gallery.technet.microsoft.com/v144-of-the-Exchange-2010-1912958d.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

For pure storage design for Hyper-V, please use the “Hyper-V” forum which would be the best place for the question For exchange storage, the information below will help: “Best Practices for Supported Storage Configurations” section in Understanding Storage ConfigurationPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
