  Aruba's ClientMatch plays 'The Dating Game' with your Wi-Fi and devices by Zeus Kerravala

  Those of you in my age demographic might remember an old, cheesy game show called "The Dating Game" with an even cheesier host named Jim Lange. On the show, bachelors and bachelorettes answered totally pointless questions to measure their compatibility with one another. It was a TV game show version of Match.com, if you will.However, sometimes it’s not just people that need help connecting to one another and finding the best match, it’s also devices. Ever try to hop on a wireless network and...

  Addressing the 'only MPLS offers predictability and supports enterprise VoIP' myth by Andy Gottlieb

  Having knocked down a number of the myths of why enterprises "need" MPLS over our last few columns, let's now address the most difficult – and in many ways "legitimate" – myths around MPLS. They can be worded different ways, but boil down to the claim that MPLS delivers reliable, predictable application performance for the enterprise, while using Internet connectivity does not. These myths can be worded in any number of ways, including: "There is no QoS on the Internet, so I need...

  Yahoo couldn't have paid too much for Tumblr by Zeus Kerravala

  The saying "Go Big or Go Home" was clearly taken to heart this weekend for Yahoo CEO Marissa Mayer, as was evident in the company's $1.1 billion cash deal to acquire the blogging platform Tumblr. As part of the deal, current Tumblr CEO David Karp will stay on and run Tumblr, which will remain an independent company, according to the Wall Street Journal.When Mayer took over Yahoo, one of her goals was to make the company brand appeal to a younger audience. Some might consider the $1.1 billion...

  MTU Size Issues by Scott Hogg

  The Maximum Transmission Unit (MTU) is the largest number of bytes an individual datagram can have on a particular data communications link. When encapsulation, encryption or overlay network protocols are used the end-to-end effective MTU size is reduced. Some applications may not work well with the reduced MTU size and fail to perform Path MTU Discovery. In response, it would be nice to be able to increase the MTU size of the network links.   MTU Size The Maximum Transmission Unit (MTU)...

  Cisco to SDN: Bring It On by Jim Duffy

  Never one to back down from a challenge, Cisco CEO John Chambers expressed unbridled confidence in the company's position as it faces down its next test: the advent of SDNs. Backed by a $180 billion installed base, dominant market shares in routing and switching, a bang-up third quarter that proved it is outmaneuvering rivals, and a track record of continued success over two decades of industry upheavals, Chambers told the SDN industry to bring it on."We feel very confident in our leadership...

  What Can Be Done About the Cybersecurity Skills Shortage? by Jon Oltsik

  I’ve written countless times about the cybersecurity skills shortage but here’s a quick summary of a few ESG research data points that illustrate the scope of this problem: 1. 25% of mid-market (i.e. 100 to 999 employees) and enterprise (i.e. more than 1,000 employees) report a “problematic shortage” of IT security skills. 2. 36% of organizations increasing IT headcount this year plan to hire information security staff. Of all the IT headcount being added in 2013, hiring information...

  Brocade CEO Carney challenges status quo in networking by Zeus Kerravala

  The interesting thing about chili con carne is that you can have variations in the flavor and quality of the food depending on how the different ingredients are tweaked and mixed together. The same thing can be said for tech companies. Bring in a new CEO, tweak a few things, and get different results. The Mike Klayko era of Brocade is now in the books, and its time for the newly appointed CEO, Lloyd Carney, to make this version of Brocade his own. It appears he is doing so by looking ahead and...

  A conversation with Suresh Vasudevan, CEO of Nimble Storage by Larry Chaffin

  1. So why don't you tell us where you think the markets are at with storage to start? The storage market, estimated at ~$33B (systems spend without including storage software and services), is witnessing dramatic changes driven by the arrival of flash as a new persistent storage medium, complementing the exclusive role that HDDs have traditionally played within Enterprise storage systems. For decades, HDDs have done well in helping to address data growth in enterprises as they steadily...

  100G, SDN leaving older switches behind by Jim Duffy

  Unlike Juniper core switching customers, HP users can still expect some significant upgrades to their older switches even though HP unveiled two new platforms for the data center last week. HP plans to equip the four-year-old 12500 data center core switch with 40G Ethernet before the end of the year.Juniper is capping hardware development on its five-year-old EX8200 and encouraging customers to replace it - chassis and all - with the EX9200 for 40G, 100G, SDN programmability, etc. There is no...

  Top vendors at Interop 2013 by Zeus Kerravala

  There’s a Katy Perry Song called "Waking Up in Vegas" in which the young Miss Perry sings "Shut up and put your money where your mouth is / that’s what you get for waking up in Vegas." That first line, "Shut up and put your money where your mouth is," should be the theme for Interop. Vendors all across the network market come to Mandalay Bay to show off their latest products and impress buyers, channel partners, media and Wall Street. The following is a list of vendors that I thought did indeed...
