The Nexus 9000 line provides 60Tbps of switching capacity and 576 40G line rate ports with a 50 percent+ reduction in ASICs per module compared to merchant silicon-only alternatives, Cisco says. It also scales to 55,000+ 10G ports and 64,000 tenants the company says.
Cisco says its ACI data center switching configuration can deliver up to 75 percent total cost of ownership savings compared to merchant silicon-based switches and software-only network virtualization by eliminating the "per VM tax," using existing cabling investments, and deploying a backplane-free modular switch chassis that reduces power and cooling costs by 15 percent.
Cisco says it can offer the Nexus 9000 with 288 40G ports at a starting cost of $75,000. Efficiencies in 40G cost are achieved through Cisco's 40G BiDi optics, which feature atomic counters for system level telemetry and a built-in line rate directory, the company says.These optics will be added to other Cisco switches over time, the company says. Cisco has also initiated a technology migration program for Catalyst 6500 data center customers, the details of which were not available at press time.
Cisco says the Nexus 9000 and ACI do not obsolete other older Nexus switches and fabrics, like FabricPath, because they serve a variety of needs in Cisco's $15 billion installed base.
