DataCenterKnowledge posted a video presentation today we would love to share with you too. It features Dante Malagrino of Cisco and Ed Bugnion of Nuova Systems with an explanation of how data center managers can use the new Cisco Nexus 5000 Series switches to optimize their virtualization efforts (Cisco recently introduced the 7000 Series). Prior to joining Cisco, Bugnion was a co-founder and chief architect of VMware.
