2012 Year In Review

Two things I greatly enjoy about working in and around Data Centers are that so many different technologies converge within them and that those technologies are constantly evolving.  There’s always something new to explore.

It’s no surprise then that Data Center Deconstructed ping-ponged among several topics in 2012, from choosing a site to relocating servers to incorporating alternative energy, and more.  I even tried my hand at blogging in real-time, posting live from the annual Technology Convergence Conference.

Here’s are the Data Center Deconstructed topics that received the most attention this year.  Check out any you’ve missed: Read More »

Collaboration is Hot … Mobility First

In thinking back over this past year and on the many, many conversations I’ve had with customers, I believe that mobility is really top of mind when it comes to all of the collaboration technologies available to us.  Over 80% of customers I’ve talked to are in the midst of developing their mobile device strategies, policies and processes right now. Once those strategies are in place, IT leaders will become very aggressive about deploying them. Read More »

ACE Network: Making Voice Calls Easier with Cisco Unified Mobility Single Number Reach

I use my desk phone only about once a day, but most callers still reach me on their first try. How is this possible? With Cisco Unified Mobility: Single Number Reach (SNR), a feature that allows me to control how incoming calls are sent to my desk, mobile, or soft phones.

Although this SNR feature has been supported on Cisco Unified Communications Manager for many years, recent versions that we’ve been testing on the Cisco ACE network extend it to all of the phones and video endpoints I use in my work.

Most ACE network users are salespeople, so SNR is a great tool for helping them stay in touch, especially when traveling, working away from the office or during the holidays. With this in mind, we conducted a study that showed that Cisco could potentially gain the value of more than US $130 million per year from improved productivity by adopting SNR — and that is only taking salespeople into account!

Upgrading Five UC Clusters to Cisco UCS Reduces Servers and Costs

In an earlier post, my colleague Reid Bourdet described how we migrated our largest Cisco Unified Communications Manager (Cisco UCM) cluster to a virtual machine environment running on Cisco Unified Computing System (Cisco UCS) servers.  This was the 19-node (server) Cisco UCM cluster that serves the Cisco headquarters campus in San Jose, California; and we completed the migration over a weekend.

What makes that move even more interesting is that we’re nearly done consolidating 5 separate clusters into one virtual environment, and reducing the total number of servers by a factor of four. Virtualization on the Cisco UCS hardware allows us to consolidate multiple UCM nodes on a single blade.  In this post, I’ll provide more details about the scope of this migration, the results we’ve gained, and how we’ll continue migrating other Cisco UCM clusters to Cisco UCS servers around the world.

Here Comes the Sun

When I was a kid, one of my neighbors had a solar radiometer.  It’s a glass bulb about the size of a baseball, with diamond-shaped panels connected to a spindle.   The panels, black on one side and silver on the other, would turn on the spindle when exposed to light.

I enjoyed experimenting with the gizmo, edging it in and out of the sunbeam that shone through a window and onto their kitchen table.  How close to the light did the radiometer need to be for the panels to move? What if I shaded it with a piece of cardboard?  How fast would the spindle turn if I put the radiometer fully in the light? Read More »
