Configuration Question
- I have a HP DL-185 Storage Server (running Windows Storage Server) with 1.2TB of disk space. I have 2 BL-460 blades as VM Hosts running Windows Server 2008 DC (64-bit) but I'm only utilizing one at present. There is a possibility of adding 2 more hosts. The VMs I'm creating are using approximately 40GB of disk space.
I formatted the entire 1.2 TB but only present 120GB to the first VM host. I'm now wondering what the best practices would be. Should I present the entire 1.2TB to the first VM and all subsequent VM hosts or carve up smaller chucks to each host? Will this imapact my ability for setting up a clustered environment or moving VMs from one host to another?

- Hello,
Are you using Hyper-V RTM or evaluating Hyper-V R2? In Hyper-V RTM you need to allocate one LUN per VM to allow for the clustered migration process to function properly. The LUNs are moved from host to host, allowing for quick migration and failover processes.
In Hyper-V R2 you can use Clustered Shared Volumes. Here is an article overviewing this technology, which allows for Live Migration: http://technet.microsoft.com/en-us/library/dd446679(WS.10).aspx
