Virtualization tipping point

摘要

While I accept that x86-based server vir-tualization is a growing fact of life in the data center, it wasn't until I took a troubleshooting class at Interop Las Vegas in May that I fully understood why server virtualization is about to go further, faster.rnThe trigger isn't virtualization giant VMware's recent release of vSphere 4, although this major platform release is fundamental to further virtualization adoption. The trigger isn't the recognition of the improvements that Microsoft's Hyper-V and the upcoming release of Windows Server 2008 R2 will bring.rnNo, server virtualization is poised to go further and faster because of something Cisco is about torndo-but it has almost nothing to do with that company's release of its Unified Computing System. Cisco is wrapping up the beta tests of its Nexus 1000v virtual switch. With the release of VMware's vSphere 4, third-party switches including the Nexus 1000v can be incorporated into the virtualized data center infrastructure. The significance of this news is hard to overstate.
