MS SQL Server 2008 Metro Cluster with same subnet

Hi All,

I want to setup SQL 2008 Active / Passive Cluster for OCS 2007 between two Data centers, Both DCs are same location which building 1(DC1) and building 2(DC2).

I am planning to use Hyper-V cluster between two DCs and then create SQL 2008 VMs then  create another windows 2008 with SQL clusters.

For the above solution, I need to use ISCSI based EMC VNX-e storages on both DCs and do the replication.

Is there any other better solution to perform? Please help me to provide more infromation.
