Feds Greatest Security Fear? Hacktivists
Potential cyberthreats from foreign governments play second fiddle to concerns over hacktivists and the insider threat, a report finds. BYOD and mobility are second only to social media.
Network the 'Next Big Thing' For Virtualization?
The concept of network virtualization seems to be gaining a lot of momentum across an industry that has virtualized most anything to do with IT. Can the same successes be applied to the networking market, transforming how systems communicate and revolutionizing infrastructure by abstracting the physical network from the demands of applications?

Broadcom Enables Programmable 100-GbE Switches
With Internet back-haul switches being asked to handle exponentially more traffic, most service provider and Internet back-haul networks are going to completely skip over the 40 GbE step and go straight to 100 GbE. Broadcom has introduced a new line of switch processors that can be reprogrammed to add new functionality to the switch and support new protocols as they come along.
How To Tackle The Big Data Challenge (Part 1)
Big data is a term getting bandied about a lot these days. It describes the phenomenon of information that keeps growing in organizations, thanks in part to the growth in social media. According to the InformationWeek Research: The Big Data Management Challenge survey of technology professionals, regardless of industry, the five top data drivers are financial transactions, email, imaging data, Web logs, and Internet text and documents.
The two main benefits of big data management are being able
RingCentral Puts A PBX In The Palm Of Your Hand
Telephony has certainly done its share of morphing during the last decade, as IP networks have invaded pretty much all communications spaces. The traditional PBX has given way to server-based voice systems, and wireless networking has stretched the paradigm even further. Enter both the cloud and mobile apps, and we have RingCentral’s latest strike in the battle for ever-more-powerful business communications.
HP: When 'Good' Security News Isn't
HP is just the latest in a long list of security vendors touting its comprehensive cyber security report showing what the most recent threats are, how they’ve changed and--sometimes subtly, sometimes not--how their security technology can protect you. But its study is another illustration of how the tech industry is constantly playing catchup with the criminals. HP’s report also illustrates how seemingly good news can turn out to be bad.
Brocade Broadens 16-Gbps Fibre Channel Portfolio
Brocade is broadening its line of 16-Gbps Fibre Channel switches with the introduction of the entry-level 24-port 6505 Switch, and has identified IBM as its first OEM partner to deliver a 16-Gbps Brocade switch as a component of the IBM Flex System x240.

Cisco Offers More SDN Hints, Confirms Insieme
Despite months of rumors and speculation, the networking industry's most powerful and influential vendor, Cisco Systems, is continuing to keep its plans for software-defined networking (SDN) largely to itself. In an exclusive interview during this week’s Open Networking Summit (ONS), Shashi Kiran, senior director of market management at Cisco, also an ONS member, says that OpenFlow and SDN are both so new that companies should not be deciding whether to use OpenFlow but rather how they can
SDN Implementations Proving Its Value
"SDN is ready to go," says Kaoru Yano, chairman of the Japanese tech giant NEC to his audience at the Open Networking Summit in Silicon Valley this week. At a conference last fall on software-defined networking (SDN), many presenters spoke of the promise of SDN to bring the same type of virtualization to the network that has made server and storage IT resources more efficient. This time, presenters such as Yano described actual implementation of SDN in production data centers. Although SDN has a
Verizon, Partners Push OpenFlow, SDN
The telecommunications giant Verizon has joined with other top technology partners to collaborate on a software-defined networking (SDN) demonstration that is based on the OpenFlow protocol. The news of the collaboration was made at an Open Networking Summit being held this week in Silicon Valley.
Mobile Data Meets Infrastructure--The Time Has Come
The usual scenarios discussed for mobile data tend to involve either single-user connectivity or mobile hotspots, and rarely get into the notion of using mobile links for "important" business connections. But that is changing, as more manufacturers work the value afforded by fast-enough carrier-provided network connections into their feature sets and more customers buy in. Whether used in a primary service role, or more commonly as wireless failover, 3G and 4G data links provide some interesting
Coyote Point Brings Next-Gen Networking to Life with Innovative Appliances
When it comes to WAN optimization and application acceleration solutions, big name vendors such as F5 Networks, Riverbed BlueCoat and Barracuda normally get all the press. After all, squeezing maximum performance out of a WAN and its associated applications has quickly become job No. 1 for most network managers. However, smaller vendors are striving to one-up the big names with new connectivity methodologies and technical advancements. Case in point is CoyotePoint.
WAN Optimization Helps Networks 'Evolve'
Networks are asked to do a lot these days--from moving video and voice to connecting mobile devices to delivering applications through a browser--but the basic architecture of a WAN hasn’t changed much over time, says analyst Zeus Kerravala. Enter WAN optimization, whose goal is to improve performance to deliver apps from the cloud that look as good and perform as if they were natively installed on the endpoint device.
vMotions a Killer App for 10GbE at Vonage
Every year since the first Global 2000 company installed VMware, server virtualization has been at the core of more and more data center architectures. Vonage is one major corporation that is now making the leap, and its architects shared with me how 10 Gigabit Ethernet is playing a key role in how the organization handles vMotions.
The Dodgy World Of Vendors' Customer Case Studies
This week I've had a couple of vendors that are heavily promoting their customer case studies. In the last 10 years, I've been on all three sides of the customer case study game, and it's worth pointing out the harsh realities. In my view, customer case studies are a deeply flawed metric for product evaluation because the process around them is highly distorted, if not plain dodgy.
EMC's VSPEX Bundles, Explained
Fit for private cloud use, new packages combine best-of-breed hardware and software from a host of EMC technology partners, with more flexibility than some bundles.
EMC Unveils More Flexible IT Bundling
These days, companies basically have two options for bringing new information technology into their data centers. They can acquire all the servers, storage, networking and software from different vendors, try to put it all together and make it work, or they can buy one big appliance that’s simpler to set up but is of a fixed configuration. EMC is offering a third option that combines the best attributes of the previous options, which it calls VSPEX.
Unlocking WAN Optimization Security
In this second installment of a three-part series on WAN optimization (the first examined visibility), Network Computing looks at the security tools that protect a network so it can deliver data, video, voice, cloud applications and all the other traffic it needs to send on its way.
IBM Serves Up New Datacenter Architecture
IBM has introduced what it considers a new category of servers, a family of “expert integrated systems” called PureSystems. The company says PureSystems go beyond the various converged infrastructure or unified system approaches of its peers by adding a new middleware layer that aims to automate both infrastructure and applications, offering workflows from IBM itself, from its third-party partners, and offering IT the ability to define its own workflows.
If I Were King Of The Wireless Jungle
Given the number of players involved across all of today’s wireless and networking spaces, it is pretty amazing that our mobile connectivity is as good as it is. Regardless of what 802.11 standard you connect with, or what carrier facilitates your mobile data, the wireless world of today is generally impressive. But it could be better. If Wireless World were mine to run, here’s what I’d change. (Cue the day dream sound effects and wavy fading video.)
Network Visibility The Key to WAN Optimization
The network monitoring and analysis tool vendor Narus uses the ad catch phrase, “You can’t manage and protect what you can’t see.” While it’s maybe not up there with “Just do it,” it does get to the essence of what network monitoring and WAN (wide area network) optimization are all about.
Help Desk Becoming New IT Frontier?
The help desk traditionally rests among the cobwebs when it comes to IT strategic planning sessions and budgeting. Some in IT even regard it as a “necessary evil,” because it is the customary gathering place for problems and for interruptions of “production” work.
Preventing SSL Certificate Authority Breaches
SSL (X.509) certificates have been the backbone of public key infrastructure and privilege management infrastructure since virtually the onset of the Worldwide Web. But in recent years, SSL certificates have been in the headlines for all the wrong reasons, with certificate authorities (CAs) from RSA to Dutch company DigiNotar suffering high-profile breaches.
Cisco Upgrades Ad Hoc Mobile Network Routers
Cisco Systems is introducing upgraded versions of two recently developed routers for deployment on ad hoc mobile networks, which are networks set up on short notice for a specific reason such as a public safety operations at a disaster site, or military operations in a battle zone. The 5940 ESR and 5915 ESR routers are based on the Cisco Mobile-Ready Net (CMRN) architecture for scalable mobile networks. ESR stands for embedded services routers, referring to the various capabilities built into th
Google, HP Raise Data-Center PUE Bar
Running rows and rows of servers, storage appliances and networking equipment makes the electric bill a data center receives at the end of each month a whopper. That’s why data-center operators are constantly working on ways to improve energy efficiency. A couple of tech companies in Silicon Valley have reported considerable progress in improving energy efficiency, and a national organization shows the average energy efficiency also improving, though some data-center operators are having m
Science Probes Why Tweets Go Viral
Whether it's a cat video or a news story, what is a Twitter post's likelihood to spread? The answer has more to do with the structure of the network and our limited attention spans than the content or author, says an Indiana University study.
Where Do Hypervisors Go From Here?
The history of the personal computer is a series of wars--operating system wars, network OS wars, browser wars and then virtualization wars. But while virtualization at first followed the lead of the OS in battles between hypervisors, such as VMWare’s vSphere and Microsoft’s Hyper-V, virtualization is increasingly following the leads of the other pieces of infrastructure before it and is enabling user organizations to set up heterogeneous virtualization networks by supporting multipl
Infoblox Automates Network Virtualization Changes
Infoblox has introduced a new platform to automate the previously manual process of making network changes associated with virtualization deployments. The launch of its automation offering is accompanied by the release of an Infoblox-backed industry survey that shows communication and collaboration across various IT silos, including servers, storage, networking and software, is sorely lacking.
Blue Jeans’ New Pricing Dubbed An ‘MCU Killer’
Blue Jeans Network, which offers videoconferencing in the cloud, has introduced a new pricing model targeted as a direct broadside to expensive systems from vendors such as Cisco Systems and Polycom. It will now offer its service at a rate of $299 per port, per month, which should be dramatically less expensive that those competitors that sell customers a multipoint control unit (MCU) to install and maintain on the customers’ premises. Blue Jeans calls this strategy an “MCU Killer.
Wyse Can Add Up to $2.5B to Dell Revenues
Financial details of the purchase price of today's announcement that Dell will acquire privately-held Wyse Technology were not released, but company executives put Wyse' 12-month revenues at $375 million, up 45% year-over-year. The associated server, storage and services revenues attached to the original thin-client sale average 5X, i.e. $5 of additional hardware, software and service sales for every $1 of the Wyse sale.
I'm Your Customer, Not Your QA Department!
Bugs are operational failures by vendors and that not only wastes company's time tracking down, but has the long term impact of stopping companies from adopting new products and features for the sake of reliability. Here are 4 misconceptions vendors tell themselves, and us, about software bugs.
Aternity Goes Beyond Simple MDM
Better network management products have always been about rapidly boiling down complex environments into words and graphics that network administrators can easily draw accurate conclusions from. Server admins and router jockeys alike know the value of good management frameworks for end-user experience measurement, and now Aternity looks to bring the same philosophy and deep views to the mobile device realm.
Apple Continues Enterprise Blitz-Crawl
Thanks to the rising popularity of the iPad, Apple’s influence within the enterprise is growing, but not with rocketing speed as one might suspect. Still, the advantage appears to be on Apple’s side, even if corporate IT managers view the vendor’s hardware as an afterthought.
More Security Breaches: Denial Not An Option!
It has happened again. Another breach. Another report of millions of credit card numbers at risk. Another round of media coverage. Another reminder that despite all the sophisticated technology that enterprises have deployed to protect computer networks, these breaches still happen. But despite the negative publicity that comes from continuing reports of such breaches, the need to be vigilant about thwarting such attacks remains, says Steve Durbin, global vice president of the Information Securi
