摘要：In the current situation of the economic crisis,when companies target budget cuttings in a context of an explosive data growth,the IT community must evaluate potential technology developments not only on their technical advantages,but on their economic effects as well.More then ever,the old cliché “doing more things with fewer resources” is true today.Many IT companies started building very large facilities,called data centers (DCs) or Internet DC (IDCs),which provide businesses a wide range of solutions for systems deployment and operation.In recent years,the IT departments around the world have moved from data center and infrastructure consolidation to virtualization.Data center virtualization is the process of aligning available resources with the actual needs of the offered services,moving from physical servers to virtual servers,sharing and provisioning servers,networks,storage,and applications.By taking advantage of three basic innovations — virtualization,tiered storage architectures and dynamic provisioning software — an organization can achieve greater efficiencies in their current computing environment.Such a unified computing architecture offers end-to-end virtualization;all structures are optimized for virtualized environments,from the CPU to the aggregation layer.In combination with embedded management,this new approach increases responsiveness and reduces the opportunities for human error,improving consistency and reducing server and network deployment times.
