One part of my job involves designing the virtualization model for our internal unified communications (UC) system deployments around the world. A critical task in this design is specifying which UC virtual machines (VMs) can share a Cisco Unified Computing System (Cisco UCS) server chassis or blade and which ones can’t. When migrating UC servers to a shared virtual environment, we need to make sure we carefully balance each VM’s needs for CPU, storage, network and memory. Read More »
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!
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.
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.

There’s a lot of collaboration technology out there and deciding which technology to invest in can be daunting. How often have you heard of a company making a major investment in technology for it to become “shelfware” and never see deployment? How often have you heard of a company that’s deployed a technology, yet nobody in the company is willing to use it? How often have you heard of a company that has several products from different vendors that do exactly the same thing?
It doesn’t take much to realize that each of these situations has a negative impact and the cause of each situation stem from different reasons, but usually with the best intentions. Shelfware occurs because of undeployed licenses in ELA’s or quantity purchases for better per seat pricing. Unfortunately, the business doesn’t grow and the company is obligated to pay for unused licenses. Other times, a company deploys a product with great features that is too complex or doesn’t integrate well with workflows and remains unused. Lastly, individual departments may make purchase decisions based on their needs without consulting IT or other departments resulting in redundant solutions that compete internally with each other.
In considering collaboration strategy, it is key to consider Read More »
