I found this very interesting atricle on how Virtualization and Cisco Nexus combine to eliminate blade servers. Now, personally I've never been the biggest fan of Blade servers. yes, maybe for Citrix environments, they seem to be perfect, but I've never seen the need and flexibility of them in virtualized environments.

The article below looks at why blade servers have never really made sense in Virtual Infrastructure Architectures, and I have to say I agree with all of it!

 With VMware Distributed Virtual Switch or DVS, one of the new features in the upcomming VMware VI4, allows you to create Virtual Switchs at a cluster level and assign ESX Servers to them. Up to now, in VI3, virtual switches can only be created at a host level, and if in a DRS/HA Cluster, these virtual switches are normally configured the same across all hosts. With DVS, you only have to create a virtual switch once and assign it to all hosts. It also allows you to migrate virtual machines on existing virtual networks to a new network all with a few clicks!

Both virtual machines have the same IP address and the same MAC address.
