Your network contains a Virtualization environment that includes the following：
- 10 hosts that run VMware ESX Server 4.0
- Microsoft System Center Virtual Machine Manager
- 50 Hyper-V hosts that run Windows Server 2008 R2
Each virtualization host contains a minimum of 15 virtual machines （VMs）.
You need to ensure that network technicians can manage and create virtual networks on the Hyper-V hosts. The technicians must be prevented from configuring other Hyper-V settings.

Your network contains an Active Directory domain. All domain controllers run Windows Server 2008 R2 Service Pack 1 （SP1）. You need to recommend a design for the Hyper-V host infrastructure that meets the following requirements：
- Maximizes storage performance.
- Remains available if a host server fails.
- Minimizes hardware and software costs.
- Supports redundant access to shared storage.
