To me the true story is another one: cisco is not able to do a real modular IOS (not counting the VM system in N as modular)
You're of course wrong. IOS-XR is example of 'real modular IOS'. ION for 6500 was executed quite succesfully, the problem is there's little installed base (out of close to 2 million of 6500 in use, which means propably there are currently more ION users than entire number of modular switches some competitors managed to sell in total) of users willing to stay with it, so it seems that the current/future HA features of monolithic IOS are OK for most of the current installed base of 6500 users. Yes, ION had a lot of problems 'for starters', because the very fundamentals of the ION were a bold departure from the architecture of IOS. But there are some specific architectural points that can't be either easily or not at all fixed with software, that's why Nexus 7k was born as a DC-oriented switch, with fabric separation from the RPs (and zillion other features), and the load on the 6500 platform to be 'one for all' deployments was lessened. -- "Everything will be okay in the end. | Łukasz Bromirski If it's not okay, it's not the end." | http://lukasz.bromirski.net _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
