Starting yesterday I began to deploy our Nexus 9000 ACI solution into our Datacentre. Scary yet fun times are ahead.

Over the course of the project I will do my best to chronicle anonymised info that talks about what we did and how we did it. Some of that may be of use to another ACI hopeful, whereas some will be pretty specific to my environment. One thing I won’t be doing is reinventing the blogging wheel, and I will chose to refer to others that helped me, rather than rehash the same subjects over and over again.

Today I was reminded what a great git of Kit the really is. Its essentially a box that gives you Serial Access to a device via an RJ45 (Cisco pin-out) using WiFi, Bluetooth or wired, using a web GUI, or a bonkers driver setup on your machine.

For me, I use the AirConsole at work in a jack of all trades way.

• I cable the Serial Dongle to the Router
• I have a WiFi client profile configured that will auto join my (pervasively configured) corporate dirty network.
• I have a WiFi AP setup in the AirConsole that securely presents a new network that I can join to access the Serial Port
• I have NAT configured on the AP->Client WiFi so that I can still access the internet from that client Laptop
• I have the Ethernet port configured to bridge with the AP interface, so I can get a wired device to connect to the Serial setup, and the internet.

So, most of the time what I find myself doing is plugging in the AirConsole, then going to a nearby desk and connecting to the AirConsole Web interface via HTTPS over the dedicated WiFi. I can then configure my box, and still access the internet.

This week is a first for me. I’m at Cisco Live in San Diego. It’s been pretty awesome so far I have to say!

Full Disclosure, I was brought here by Cisco to talk to Analysts about ACI. However, I should also point out my only session was closed door feedback on why we chose the solution, and how its helped us to date. Since we are only at the early stages, it was a short conversation. I thank Cisco for their hospitality, and for allowing me to access Conference Level sessions that my explorer level pass would not normally allow.

Oh how the world has changed since I started out in the wonderful trade.

We used to have VLANs and subnets; switches, routers and firewalls. People would moan things didn’t work and we did a traceroute to figure out why. We would bash out a fix, and if it broke, we would bash out another. It was the wild west, and that was fun. Cowboy hats were standard issue.

Then along came the bad guys, and with them, the policy doctors. Changes became more structured and requirements became more complex. Environments spiraled out into wider geographical areas and management became less about break fix and more about tightly structured architecture. The industry responded with protocols and toolchains, each with their own use case, and bit by bit, the sector split up into the key areas of WAN, DC and Campus.
