Aerohive's new access points remove deployment barriers

With so many IT departments debating how to increase their Wi-Fi capabilities, Aerohive is targeting a growing market.
Submitted by Zeus Kerravala on Wed, 04/16/14 - 9:42am.

To say Wi-Fi is hot is as big an understatement as saying that A-Rod is a cheater. Everyone knows it’s true, but it’s bigger than most people think. In a joint ZK Research/Tech Target Network Purchase Intention Survey that was run near the end of 2013, Wi-Fi ranked as the No. 2 in priority for network managers, behind only the red-hot security market.

QFabric vs MetaFabric: What's the difference?

The first thing to understand is that while QFabric and MetaFabric are related, MetaFabric does not in any way replace QFabric.
Submitted by Zeus Kerravala on Mon, 04/07/14 - 10:31am.

I believe Juniper was the first mainstream network vendor to use the term "fabric" aggressively to describe its next-generation network architecture when the company announced QFabric back in early 2011. There may have been another vendor that used it first, but Juniper made it mainstream. Since then, almost every network vendor uses the term “fabric” broadly, and Juniper itself announced its next phase in fabric-based network when it unveiled MetaFabric in late 2013.

Gigamon goes modular at Interop

One of the more interesting announcements I saw from the first couple of days at Interop is Gigamon's Multi Purpose Visibility Fabric Node.
Submitted by Zeus Kerravala on Thu, 04/03/14 - 7:47am.

Well, it’s that time of year again. The snow is finally off the ground in most of the New England area, opening day of Major League Baseball has come around, but most importantly, it’s Interop time in Las Vegas. This year’s Interop is about a month earlier than Interop of years past, but the activity from the show seems just as high. One of the more interesting announcements I saw from the first couple of days is Gigamon’s Multi Purpose Visibility Fabric Node.

OpFlex: Another example of Cisco being Cisco

Cisco's alternative to OpenFlow could put the company in a good position in the software-defined networking market.
Submitted by Zeus Kerravala on Thu, 04/03/14 - 7:26am.

Why do customers pay a premium for Cisco? My research shows that Cisco owns about 75% of switching share but only about 55% of port share, showing Cisco’s obvious revenue per port advantage over everyone else. Why does this discrepancy exist? I know some of you will disagree with this, but in general, customers pay up for Cisco infrastructure because it does more stuff faster than competitive products.

For a couple of years now, Cisco CEO John Chambers has been proclaiming that Cisco will be the world’s No. 1 IT vendor. This proclamation has been met with mixed reactions as the IT community has many large, incumbent vendors already.

Troubleshooting Cisco's IWAN: It all depends on network visibility

Cisco's IWAN technology can help resolve some issues with network management, but it could present some challenges itself.
Submitted by Zeus Kerravala on Mon, 03/17/14 - 11:10am.

The network industry has largely been focused on network transformation over the past few years. Most of the vendors, though, have been geared towards the evolution of the data center network. It’s time that businesses started looking at evolving the wide area network (WAN) as this is often where the biggest pain points is for application performance.

Big data can help accelerate UC adoption

The unified communications industry can benefit from the "big data" trend, particularly when it comes to accelerating the deployment of UC.
Submitted by Zeus Kerravala on Fri, 03/14/14 - 11:44am.

Enterprise Connect, the industry’s largest and best show dedicated to Unified Communications and all things collaboration, kicks off next week in Orlando, Florida. I’m expecting to see the typical themes: interoperability, cloud, video and Cisco versus Microsoft. Another theme I’m expecting to see become a bigger topic is “Big Data” for Unified Communications.

How Aruba Networks is targeting 'GenMobile' workers

At its Atmosphere event in Las Vegas, Aruba Networks announced its Mobility Defined Networks architecture.
Submitted by Zeus Kerravala on Thu, 03/13/14 - 11:24am.

This week, Aruba Networks is holding its Atmosphere event in Las Vegas. Atmosphere is actually a collection of conferences – Airheads user event, Partner Summit, Investor day, and an IT Executive Forum - so it provided a great venue for Aruba to announce its Mobility Defined Networks (MDN) architecture. The primary driver of an MDN is the changes in network traffic and user behavior from the rise of GenMobile workers. If you aren’t familiar with GenMobile, it’s the term that Aruba has started to use as the set of workers that precede GenY, which preceded GenX.

So you want to adopt SDN: Where do you start?

Although many target the data center to get into software-defined networking, the WAN could be a more beneficial place to start.
Submitted by Zeus Kerravala on Mon, 03/03/14 - 3:27pm.

Software Defined Networking (SDNs) has been the hottest topic in networking over the past few years, and will likely continue to be over the next couple. It’s certainly dominated the traffic on this site and others.

Brocade's fabric strategy appears to be working

When the rest of the industry chased SDNs, Brocade stayed focused on fabrics, and it's paying off.
Submitted by Zeus Kerravala on Thu, 02/27/14 - 11:38am.

The networking industry has certainly gone ga-ga over the topic of software defined networks (SDN). Before SDNs were all the rage, network transformation had already begun with the use of fabrics. The rise of SDNs certainly took the media focus away from fabrics and that caused many vendors to shift their marketing messages as well.

However, one of the vendors that has been fairly consistent with the value of a fabric is data center specialist Brocade, and its strategy seems to be working.

Did Facebook overpay for WhatsApp?

How will we discuss the WhatsApp acquisition when we look back on it years from now?
Submitted by Zeus Kerravala on Thu, 02/20/14 - 3:22pm.

This week, Facebook opened its wallet and shelled out a whopping $19 billion for WhatsApp. Most people think of WhatsApp as an over-the-top messaging application, but I think the company is much more than that.

VMware jumps into mobile, but lacks network control

While the AirWatch acquisition was necessary, it doesn’t fully satisfy the needs of customers looking to manage and secure mobile devices.
Submitted by Zeus Kerravala on Thu, 02/13/14 - 2:54pm.

Last month, VMware made a big splash in the Enterprise Mobile Management (EMM) market by plunking down over $1.5 billion for AirWatch. EMM, formerly known as mobile device management (MDM), has been one of the hottest market segments in tech, primarily due to the seemingly unstoppable force know as BYOD. This acquisition comes a little over a year after Citrix purchased Zenprise to complement its mobile offering.

Why the NFL is turning to Wi-Fi analytics

Although the Super Bowl was a complete failure for Peyton Manning and the Denver Broncos, network data shows that it was a smashing success for the NFL and its fans.
Submitted by Zeus Kerravala on Wed, 02/05/14 - 9:46am.

This has been quite the past half a year for the once-beleaguered Extreme Networks. Given all the change in the industry and all the media focus on network startups and SDNs, Extreme Networks had almost become the forgotten-about network vendor. Six months ago, Extreme’s stock price was trading at a little over $3.50/share and the company had recently gone through a CEO change.

Top 5 ways that IT wastes money

A number of common IT projects that seem like they should add value rarely do. Here are what I consider the top IT projects that waste budget dollars.
Submitted by Zeus Kerravala on Mon, 02/03/14 - 10:42am.

The role of the CIO has changed more in the past five years than any other position in the business world. Success for the CIO used to be based on bits and bytes, and is now measured by business metrics. Today’s CIO needs to think of IT more strategically and focus on projects that lower cost, improve productivity, or both, ideally.

However, many IT projects seem to be a waste of time and money. It’s certainly not intentional, but a number of projects that seem like they should add value rarely do. Here are what I consider the top IT projects that waste budget dollars.

Gigamon's Netflow Generation app should prove useful

A new app bodes well for Gigamon's recent hot streak.
Submitted by Zeus Kerravala on Fri, 01/24/14 - 10:01am.

Big data and analytics are hot topics of conversation for almost anyone in IT today, including network operations. This is one of the reasons Gigamon has been on a tear over the past couple of years, especially since its IPO last year.

Last week, Gigamon announced an upcoming application to generate and export NetFlow records from its visibility fabric. The NetFlow Generation application will create NetFlow records and then send that information to one of the many NetFlow collectors and analyzers available on the market today.

It's finally, actually time for video to be pervasive

Even though it's been said every year, 2014 is the one when we'll see significant change in video as a collaboration tool.
Submitted by Zeus Kerravala on Thu, 01/09/14 - 1:25pm.

As a mainstream industry, video communications has been around for well over two decades now, and it seems that every year we hear that “this is the year that video becomes pervasive.” And then it doesn’t happen.

However, I’m here to say it again, this time with confidence - 2014 is a year of significant change and one where we finally see video become a mainstream collaboration tool.
