I am using open-e on a server that I am attempting to turn into a SAN. My vm host servers are running 2008 Server R2 with Hyper V (not the core installation I installed the OS).

I just created Volume Groups. I want to create disk partitions and put a virtual machine on each one. I want to create iscsi connections so that the VM is on the open-e storage server and my other server with hyper V can connect to it with iscsi connection.

Should I use File or Block I/O for a Hyper V setup? and if it is File what speed it shows slow, medium fast?
