Cisco has recently introduced the Virtual Security Gateway for the Nexus 1000V. According to this report on InformationWeek, the company expects the virtual appliance to be adopted by its Unified Computing System (UCS) users as a way to extend security measures.
“Nexus 1000V is a software switch that Cisco supplies as a substitute for the virtual switch inside VMware’s ESX hypervisor. The substitution brings scalable efficiencies to the operation of virtual machines under the hypervisor. Network connections to virtual machines can be set up with governing policies, and once set up, the connections function as the equivalent of a server port and network interface card tied to a network and a particular server’s operation in the physical world.”
