Last sunday we talked about how Juniper is trying to put its feet into the race of datacenter switching championship with the launch of its revolutionary product Qfabric but today when I read about Cisco ASR 9000 Network Virtualization Technology (nV), after Cisco Nexus FabricPath It became pretty clear that taking on Cisco is not going to be easy for anyone. Lets see what Network Virtualization Technology (nV) is -
Cisco ASR 9000 routers comes loaded with a feature called Network Virtualization Technology (nV) which enable you to create a logical group, virtual chassis or virtual stack whatever you wish to say. It enable you to view multiple chassis as a single logical unit or to be precise two Cisco ASR 9000 Series platforms as a single virtual Cisco ASR 9000 Series system. Effectively, they can logically link two physical chassis with a shared control plane, as if the chassis were two route switch processors (RSPs) within a single chassis. As a result, service providers can double the bandwidth capacity of single nodes and eliminate the need for complex protocol-based high-availability schemes, while achieving failover times of less than 50 milliseconds for even the most demanding services and scalability needs.
To add more to it nV technology is loaded with feature called Virtualized Access - which enables you to view or configure or operate on any physical remote device as an extended line card of the router or even you can also add it as another RSP and same is achieved with Cisco ASR 9000 Series system capabilities beyond the physical chassis with remote virtual line cards. These small form-factor (SFF) Cisco ASR 9000v cards can aggregate hundreds of Gigabit Ethernet or 10 Gigabit Ethernet connections at the access and aggregation layers, but they are provisioned and managed as distributed line cards of the host Cisco ASR 9000 Series device, rather than as standalone access-routing platforms. With the capability to deploy these high-density Gigabit Ethernet devices in the field—whether in a central office, an enterprise wiring closet, a building basement, or a remote terminal—operators can provision exactly the bandwidth they need, when and where they need it, with a single management and control plane. Network operators can scale thousands of Gigabit Ethernet interfaces
I am sure this technology will reduce the number of racks from hundreds to Ten's and same would happen with the manpower requirement and yes not to mention power and cooling too...
I am sure this Video will make it easy to understand -
