Cisco IT has, as you may have heard, been shutting down some of its Data Centers. We’ve closed dozens of older facilities – some large, many small – in the past 10 years, consolidating into purpose-built rooms that better enable our business.
The latest to close was the company’s longest-running Development Data Center, located at Cisco headquarters in San Jose. It’s one of two server environments that I worked in daily when I joined Cisco in the late 1990s. Even after designing, working in, and touring many other facilities since, when someone talks about what a Data Center is that room still appears in my mind’s eye.
I took a final walk around the mostly-empty space recently. I hadn’t been in there in years and it was a bit like visiting my old high school. Things looked slightly smaller than I remembered, and several items triggered unexpected memories.

Now that US tax day is over, we in the wireless field can get back to focusing on P1: optimizing and maintaining network performance. Keeping your network in good shape is like gardening: if you don’t pull out the weeds, it’ll never look as good as it could. My friend Jim Florwick detailed the gory bits of the 802.11b penalty with its awful lag in efficiency and absolute waste of spectrum. I write today to help give you the steps to act on Jim’s order to stop the madness.
I liken this process to a memorable scene from Monty Python: You must “Bring out yer dead.” However much the first standard insists it’s still alive, let’s all be honest with ourselves: 802.11b is dead.
In memoriam of the first amendment to the IEEE 802.11 wireless networking standard hailing all the way since 1999, 802.11b was superseded by 802.11a and g in 2003 which are much more efficient. 802.11n was available in draft form in 2007 and was ratified in 2009 while 802.11ac was ratified last September. A few years from now we should be planning the wake for 802.11a and 802.11g as well.
Now is the right time to bury 802.11b and reduce the drag on your network. Let’s be real: there is a reason cyclists are not allowed on the freeway, and an 802.11b device will slow everyone down. Here are 5 easy steps for eradicating your network of 802.11b and getting on your way towards higher speed wireless:
STEP 1. Identify any 802.11b devices on your network
All of the latest Wi-Fi connecting devices are 802.11a/b/g/n capable. So how do you hunt down the 802.11b-only devices? You’ll be looking for older laptop and mobile clients (mostly before the year 2005).
Cisco Prime Infrastructure makes this easy for you with a report on clients by protocol. It will look like this:

In my first editorial in this series, I introduced the notion of some very bold aspirations for community regeneration and economic growth, that’s about to occur in East London.
I’m sharing the following key data points about the London 2012 socioeconomic impact, to give you an idea of the scale of this purposeful investment strategy — and the anticipated economic development related outcomes.

For this week’s Data Center Deconstructed we’re setting the Wayback machine to 1998, when Cisco opened a new engineering Data Center at its headquarters in San Jose, California.
