Virtualization in the data center is a major initiative that organizations of all sizes are undertaking today. There are several aspects of data center virtualization that together work as an overall solution that brings benefits like reduced cost, increased agility, and realization of the vision of the green data center. Server virtualization is one major component of data center virtualization and plays a key role in this initiative; Microsoft is a major player with its Hyper-V server virtualization solutions. However, server virtualization by itself is not a complete solution for transforming the data center, especially when combined with traditional storage. It requires far more intelligent storage, data protection, and business continuance solutions to achieve a comprehensive solution that delivers the full value of the virtualization strategy. This white paper provides an overview of how NetApp complements Microsoft Hyper-V server virtualization solutions by providing the most cost-effective, operationally efficient, flexible, and environment-friendly integrated storage, data protection, and business continuance solution. By providing this solution, NetApp and Microsoft Hyper-V combine successfully to help virtualize the data center.
