802.11ac: That’s the Answer. What’s the question?

Everybody’s talking about 802.11ac, but we’ve sensed some confusion for next steps as far as how CIO’s and IT organizations should be approaching the new standard.

3700internal2Should I move to 802.11ac?

You’re probably thinking: Chris, you’re a leader at Cisco, of course you want me to migrate to 802.11ac. That, my friends, is where you are wrong. There is no simple answer to the question of whether you should move your network to 802.11ac. Here’s my simple rule of thumb:

There is no premium for 802.11ac from Cisco. If you are deploying new Access Points’s today, you should be buying 802.11ac. If you’re not buying, you are probably satisfied with your network and how it will handle the growth of more and more clients associating with your network and the bandwidth demands that come with that client demand. If you feel you have a plan to handle this demand, then you are one of the few that can pass on 802.11ac.

That said, there is a strong ramp up for Cisco 802.11ac products in the market, the AP3700 is the fastest ramping access point in our history and we have yet to see if the AP2700 will claim that crown in the coming months. ABI Research estimates that currently 50% of new device introductions are 802.11ac enabled, a statistic expected to increase to 75% by the end of 2015.  This is enough proof of the overwhelming interest in adding the benefits of 11ac to networks. Let’s take a step back and consider the basics of why people are moving to the new standard.

Why .11ac?

Today, everything is about getting what we want, when we want it. Instant gratification. It’s not just the millennials—we’ve all been conditioned to expect things within seconds. Could you imagine the days pre-Internet if you had the capability for on-demand movies? Read More »

My Week at CiscoLive! San Francisco 2014

SDN-SDN-SDN…No longer does it stand for “Still Does Nothing”! Welcome to the world of Cisco where today is ACI and tomorrow is a stellar collaboration lineup. I hope you are prepared for a wild ride!

This year was the 25th Anniversary of Cisco Live, previously known as “Networkers”, and what an event it was! The Moscone Center neighborhood in San Francisco was abuzz with excitement as the event drew in a crowd of 22,000 registered participants.

How FCoE Helps Cisco Reduce Data Center Infrastructure

What a difference a networking cable can make in a data center’s infrastructure requirements and costs…especially when that cable uses Fiber Channel over Ethernet (FCoE) technology. An industry-standard, FCoE carries Fibre Channel over Ethernet links, which reduces the number of I/O adapters, cables, and switches in the data center.

Cisco Live Utilities Session a Big Success: Converging IT and OT (Operational Technologies) – BSAIoT-2100

May 20, 2014 at 10:21 am PST

rgeiger2Rick Geiger presented Session BSAIoT-2100 -- How to Successfully Converge IT and OT (Operational Technologies) at Cisco live in San Francisco this week, with strong interest from attendees.

Many of you know of Rick Geiger from this blog and other publications. Rick’s session at Cisco Live 2014 discussed the many aspects and challenges of merging OT and IT in organizations.  Computing and networking for operations requires more IT-based support and a growing convergence of IT and OT skill sets to support intelligent devices and varied processes. Rick’s session discussed the convergence driven by the critical needs of the OT organization for the process maturity of IT and for managing and securing the growing complexity of OT systems.

Rick Geiger CLUS AgendaIn bringing IT processes & capabilities to OT, IT will need to recognize the needs of critical control systems and the equivalent process capabilities that OT provides for engineering and operations. Successful companies will find ways to establish common ground & combine the expertise & value of both. Bringing standalone devices or isolated networks into core operational systems will bring clear and tangible advantages and business benefits to those companies.

Rick’s session topic covered new ideas & concepts that are developing around IT/OT, providing major opportunities for those who understand how to leverage their IT know-how to Operations.

The Future of Wireless: Times are Changing Before Our Eyes

We live in amazing times, ask anyone who ever had to look up a phone number in a phone book. In the past this was the only way you could find the number to your favorite restaurant if you wanted to make a reservation. Today, all we need to do is reach into our pocket or purse and grab our mobile device, open an application and in a few seconds (not minutes) we have the phone number. Not only that, but we can see the menu and make a reservation right from the device. Over time we have become dependent on carrying the world (both personal and professional) in our pocket. With mobility, we are always on, always connected: nothing—whether it’s your team’s latest score or that email from a vendor you need to send to your boss—is more than a quick search away.

What once seemed unfathomable, this way of always being connected is now commonplace. However, as the application developers sit and think of the next killer app, the IT team has to make sure the network can not only support this new app, but also assure the performance meets the higher and higher demands of new apps. This requires the network to be more application-aware. And the reality is that more applications that require higher network performance are coming at a faster rate. Add to it new devices that use these applications are becoming accessible to everyone. On top of that, the people that use these applications and devices are becoming more demanding in terms of reliability and experience. So what is an IT person to do?

“We were ahead of the times,” says Joseph Tufano, VP and CIO of St. John’s University. “But times have changed. You see it everywhere: for example, if you go to a basketball game on campus, and there’s a timeout, everybody is using their mobile devices.”

IT is always working to increase the wireless performance of the network. However, as more bandwidth becomes available, users increase their usage and consume that bandwidth. Read More »
