"Given where we are in the market it's very important for us to focus on what we're delivering," McCool says. "We're very focused on delivering the (Nexus line) and the evolution of that roadmap. This is the mainstream fabric we're supporting."
In other data center matters, McCool says Catalyst 6500 users are trading in or redeploying the Catalyst 6500 for the Nexus 7000 as they build out 10G infrastructures. In redeployments, the Catalyst 6500 is being implemented as an edge access and aggregation switch; as a services node performing firewalling, load balancing, wireless services and application monitoring; and as a virtualized security gateway, McCool says.
He did not provide additional details or timelines for scaling the Nexus 7000 to 550Gbps per slot for 40/100G Ethernet support; or for adding Fibre Channel over Ethernet to the modular Nexus 7000 core switch.
FCoE on the core switch, along with FabricPath, would allow data center users to scale network and storage convergence beyond server access and throughout the data center network.
