If you have been following the news, I’m sure you saw that Cisco just introduced Application Centric Infrastructure (ACI). Combine ACI with Cisco UCS Director and you can provision and deliver application-centric infrastructure automatically.
Over the past 11 months, I have discussed how Cisco UCS Director reduces data center complexity with unified automation and management of multi-vendor converged and integrated infrastructure systems. But the provisioning of compute, storage and network resources is just the start. IT needs to deliver infrastructure that is tailor-made for the specific applications their users need. Together with ACI, Cisco UCS Director has key capabilities to make this happen.

By now you’ve probably heard quite a bit about the newest generation of Wi-Fi, 802.11ac. I’ll save you the gory details, just know it’s about 3x faster than 802.11n and will help to improve the capacity of your network. Jameson Blandford and I were recently guests on the No Strings Attached Show podcast with Blake Krone and Samuel Clements (Click to listen to the podcast).
I wanted to follow up the podcast with a blog to go over considerations for deploying, testing, and tuning 802.11ac.
Considerations for deploying 802.11ac
The first question you’ll want to ask yourself, is, if your switching infrastructure can handle 11ac? The answer probably is, yes. The things to consider are the port speed and power-over-Ethernet (PoE) capabilities. You’ll want the access point to have a gigabit uplink to the switch. Each 11ac access point could potentially dump several hundred megabits per second of traffic onto your wired network. It’s also not a bad idea to have 10 Gig uplinks on your access switches to distribution or your core. If you have even just a couple access points on a single access switch, you may quickly find yourself wishing you had 10 Gig uplinks.
Next you’ll need to consider how you will power the access points. If you are like the majority of our customers, you will use PoE from your switches. While 11ac access points require 802.3at (PoE+) for full functionality, the Aironet 3700 will run happily on standard 802.3af PoE. In fact, it remains 3 spatial-streams on both radios, so performance does not suffer because you have a PoE infrastructure.
Will you deploy 80 MHz channels? Read More »

As a mobile expert and thought leader, I’m frequently asked about what the next big thing in mobility will be, and my answer often surprises inquirers – mobile’s future is a disappearing act.
When most people think about the future of mobility, they think of larger, possibly flexible mobile screens, thinner and lighter designs, and the incorporation of new, currently unavailable technologies, but the reality isn’t so black-and-white.
In past posts, I’ve explained why mobile devices gained ubiquity – in sum, they’re submissive to us (they’re easy for us to handle and manipulate), and the future of mobility is no exception. Think about it – what could be easier to handle than nothing at all? In time, we’ll begin to see technologies that virtually disappear until we need them, at which point we’ll see them front-and-center, or discretely in our periphery, depending on the optimal viewing location and utility offered. In the interim, mobile devices (both their hardware and software) will hybridize in an effort to complete the transition to virtual disappearance. Read More »

Fact: laying fiber communications infrastructure is expensive. Fantasy: the ability to know ahead of time how many property owners in a given neighborhood would pay for a new fiber infrastructure by subscribing to services or even – and here’s a real fantasy – paying more to get the fiber laid initially.
Except it’s not a fantasy. If you’re a telecom carrier, a cable company, a municipality, even a group of community activists, Greg Richardson is here to offer a compelling approach to capital investment in new infrastructure. And he’s done it with an idea that’s almost embarrassingly simple.

I’m happy to announce a new resource for companies with 100-1,000 employees: the Cisco Midsize Business Solutions website. Built for midsize IT and business leaders, it discusses current market influences and top challenges with insights on how to address them. With solutions, case studies, videos, and tools, it provides these leaders with the information they need to grow their business.
One of the top focus areas on the website is the infrastructure. A strong IT infrastructure is important to the success of any business. The infrastructure is how we get the applications we need to do our jobs. It’s how we collaborate with our co-workers, partners, and customers. It’s how we access the data we need when and where we need it. When it comes to midsized businesses, it’s the key to growth. Read More »
