Well, things have certainly gotten a bit more hectic since out announcements today.Understandably, most of the buzz has been around VN-Link and the Nexus 1000V. Some of you might be wondering what all the fuss is about.So, Cisco VN-link is a collection of technologies and solutions designed to deliver virtual machine aware network and storage services. essentially represents the movement into the fourth pillar of our Data Center 3.0 roadmap. With the release of VN-Link, you will see products and technologies that don’t simply support virtualization but are active participants in accelerating virtualization.One of those products is the Cisco Nexus 1000V. This newest member of the Nexus family is a pure software switch that integrates with the ESX hypervisor. Unlike other solutions, it is not an virtual appliance or the like that is external to the hypervisor, instead, through two years of combined R&D with VMware, we were able to deliver a true Cisco switch, purely in software, that is a tightly coupled extension of the hypervisor.The buzz the show is because the Nexus 1000V delivers a number of features that will accelerate the growth of server virtualization. I short, it will allow the provisioning of security and network policy at VM-level granularity. Furthermore, that policy will move with the VM if it moves as result, say, of VMotion or DRS. This greater degree of transparency improves management, troubleshooting and policy enforcement. Finally, the Nexus 1000V does all this without forcing either the server or network team to do anything different than they do today.For more info, check out this animation and go to the Nexus 1000V product page.
