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.

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?

One client for all communications: That’s the idea behind the new Cisco Jabber and I’m seeing that benefit in my use of this universal communication client. I start the client when I begin my work and use it throughout the day for voice and video calls, to send instant messages to others on my team, and to join WebEx sessions or Cisco TelePresence meetings. In addition to these features, the client also supports Desktop Sharing and Presence, which lets me know the availability status of my teammates at all times.

Since I last blogged on the topic of business apps for the enterprise, much has happened at Cisco. As you know from reading my earlier updates, we are developing an entire range of helpful and easy-to-use business apps – powerful applications that accelerate employee productivity. We’ve made much progress since June. Read More »
IT departments are often caught between the requests of users who want the latest and greatest technology right now—even if it’s not perfect—and users who value reliable and consistent IT services above all else.
How can you serve both types of users without wasting time, energy, budget, and everyone’s patience? In Cisco IT, we’ve done it by creating the Advanced Cisco Experience (ACE) network. Operating ACE separately from our production network, we use it to introduce new IT services and products to a group of technology specialists before we deploy those services company-wide. These services include new releases of Cisco unified communications, collaboration, video, and mobility technology products that our employees use to work the way they want, across different devices and locations, which drives gains in user productivity.
