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 choose a web security appliance based on user count and expected traffic profiles. Then marketing rolls out a successful video campaign that goes viral and your users complain about slow internet performance.
You’re under the gun to complete your global web security initiative on time and then you receive word that three servers are stuck in customs in a country you have never heard of.
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 »
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.
