UC on UCS – The Invisible Servers

Cisco IT completely changed our voice and video infrastructure in the data center – and nobody noticed!

We changed the systems that Cisco IT uses to run ALL our voice and video supporting:

  • 200,000 voice endpoints in 540 buildings around the world,
  • 87,000 voicemail boxes
  • 1600 TelePresence units
  • 8.6 Million Webex meetings per year
  • Our customer contact centers handling 22M calls / year

It was a big job, migrating all these services off of 574 Cisco MCS servers, and onto new Virtual Machines running on 191 Cisco UCS servers in 12 different data centers.  It took a while, but it was truly worth it, despite the fact that nobody noticed.

We reduced the amount of data center resources significantly – less space, less power, fewer cables. Even better, we now have all our voice and video running on virtual machines, making operations jobs and updates and growth a good deal easier, and faster. Best of all, though, we moved all our voice and video to a completely new server platform  — and nobody noticed!

You’re moving more and more workloads onto virtual servers to match your business agility objectives when someone from the c-suite asks, “Why do you still have these security appliances? Can’t you virtualize them, too?” Read More »

DCI Use Case: Capacity Expansion

Hi,

Today I want to bring up DCI use case that I’ve been thinking about: capacity expansion.  As you know, the purpose of DCI is to connect two or more Data Centers together so that they share resources and deliver services.  The capacity expansion use case is when you have temporary traffic bursts, cloud bursts, either planned or unplanned, maintenance windows, migrations or really any temporary service event that requires additional service capacity.

To start addressing the challenge of meeting these planned and unplanned cloud burst and capacity expansion requirements, check out the new ACE + OTV feature called Dynamic Workload Scaling announced recently.
