So, I am watching Captain Ron (hey, we all have our guilty pleasures) and it reminded me of a conversation I had with a customer back in Vegas at VMworld. The customer was giving me some friendly grief around the recent NetworkWorld lab test of the Cisco Nexus 7000 and the high availability features of the platform. At this point, you are probably wondering where Captain Ron figures into this…. …so, in pretty much every nautically-themed comedy, there is a scene where the captain is tacking and as the wind shifts, the boom shifts sides and knocks someone into the water. I see the same thing happen with vendors where a sea change (yes, pun intended) in technology will catch a vendor off-guard, and boom--into the water they go.So, in this case, the customer took exception with David Newman’s test of stateful process restart test of OSPF (256 adjacencies, advertising traffic to 50K routes, traffic on all networks), where he was able to kill the OSPF process without losing a packet or causing the routes to be recalculated. The customer contention was that a better test would have been to see how quickly the Nexus 7000 could re-converge the network. I told the customer this sounded like having an argument about who’s airbag deploys faster when it would be better if the brakes worked well enough that we didn’t hit things in the first place. In today’s operational environment, minimizing service loss is, to paraphrase my boss, using yesterday’s thinking to solve tomorrow’s problems. To meet these increasing demands in the data center, the conversation needs to evolve from”how do we drop fewer packets” to”how do we not drop drop any packets in the first place” and the data center infrastructure needs to keep up..wait, was that a splash I just heard?
