I had the distinct pleasure this week of participating as a speaker at Duke University’s Fuqua School of Business. Professor Tony O’Driscoll, Fuqua’s executive director at the Center for Technology, Media and Entertainment and a Cisco customer, hosted a “social business immersion day” with a very stimulating line-up of guest speakers.

Upgrading a critical enterprise call processing system to a completely new virtualized server platform sounds pretty tricky. Doing it from 5,000 miles away, in the public square of a sleepy Spanish village using your laptop and a VPN connection over the free municipal WiFi service sounds … well, maybe a little crazy. Recently, I did just that, migrating our Cisco Unified Communications Manager (UCM) cluster in Johannesburg, South Africa to the Cisco Unified Computing System (UCS) platform from the small village in Spain where I was vacationing.

Changing voicemail systems–or the servers they run on–can be a big, time-consuming, and difficult task. Yet recently we did both. We migrated our application platform from Cisco Unity 7.0 (2) running on Cisco 7800 Series Media Convergence Servers, to Cisco Unity Connection 8.5 running as a virtual machine onthe Cisco Unified Computing System (UCS) platform. What’s more, we completed the cutover of more than 87,000 voicemail boxes to the new platform in a single weekend.

Data Center Deconstructed reader Eric Chou writes: Good to see the knowledge sharing Doug. I read your book on building a Data Center a few years back and it was informative on the physical infrastructure piece. I think it would also be informative if you can share some of the experiences or creative ways to increase efficiency when there are macro environment limitations. I mean, outside of a select few companies (Google, Amazon, Facebook, Amazon), most companies are not able to build a Data Center from the ground up, buy the cheapest land near a lake or negotiate a jaw dropping electricity rate with the local government. What can we do when we need to house 1/2 floor of servers in a 80-year old peering exchange that assumes 2 KVA per rack when designed?
That’s a great question. As I often tell other Data Center managers, we can make any upgrades to our server environments we want to as long as there’s no downtime or cost. I’m joking with that comment – mostly – but it is a common scenario. Fortunately, there are several things that can be done in a legacy Data Center to improve its efficiency and reduce the likelihood of downtime without spending much money or disrupting the environment.
Here, then, are eight simple rules for improving a Data Center.

Attracting new talent in the workforce is a big priority for Cisco – and I’m sure for most companies around the globe. Companies spend significant time, money and effort to attract these new recruits, but are they prepared to keep them happy and retain them after they come onboard?
