You have a two-node Hyper-V failover cluster that uses SAN storage. You are designing storage for a new virtualization environment by using Windows Server 2008 R2. You plan to deploy five virtual machines （VMs） per logical unit number （LUN）. You need to be able to perform a live migration of a single VM while the other VMs continue to run on the host server.    What should you do？（）

• A、Use Cluster Shared Volumes （CSVs）
• B、Use fixed disks on the SAN storage
