Right across the street from Brocade at the newly opened $1.18 billion Levi’s Stadium, home of the 49ers football franchise.  Every fan will strike gold when they fire up their smart phone or tablet on the stadium’s Wi-Fi network. With dual high-speed 40Gig pipes, a massive Brocade switching system, and Aruba 1.3Gbps 802.11ac Wi-Fi everywhere, the stadium is a tour de force of Silicon Valley networking and fan engagement technology.

Does SDN Have a Role in Campus Networks?

by Jim Metzler on ‎09-29-2014 04:31 PM - last edited on ‎09-30-2014 10:36 AM by Community Manager (2,367 Views)

The vast majority of the discussion about SDN to date has focused on the data center. Since the network is a lot bigger than just its data center LAN that begs the question “Does SDN have a role in campus networks?”

Unlocking Flexible Security in an Enterprise World

by Prasida Menon on ‎09-26-2014 12:02 PM (1,526 Views)

One of the biggest challenges faced by the enterprise world today is how to overcome the security issues faced in many of the enterprise organizations. The early adopters of the BYOD strategies have learnt their lessons the hard way – a plethora of mobile devices in the enterprise result in huge demand for authentication and authorization framework caused by the sheer volume of devices and each device’s varied authentication interface.

Did you know that the root cause for many upgrades is not based upon new applications or user demands, but based upon Planned Product Obsolescence and Vendor-Centric Business Practices?

 

Consider the dramatic increase in incumbent network devices moving to end-of-support (EOS), from 38% to 45%, in Cisco’s product portfolio.  This was reported by Dimension Data, one of Cisco’s top notch partners no less.

Sidestepping Security Woes of BYOD

by Prasida Menon on ‎09-04-2014 09:06 PM (1,477 Views)

My previous blog detailed how organizations worldwide can adopt BYOD programs seamlessly using innovative stackable switch solutions. While a solid network infrastructure and enhanced capacity form the backbone of any BYOD program, security is one of the overarching issues faced by many organizations today. With over 23% of US based employees experiencing some form of security compromise on their personal devices in any single year, it’s not surprising that a recent Gartner study shows over 75% of organizations cite security issues as their biggest concern for adopting BYOD programs. What is Brocade's Campus solution to help mitigate BYOD security risks faced by organizations worldwide?

With BYOD strategies maturing, organizations worldwide are frantically looking to adopt BYOD programs, not only to improve employee satisfaction but also to improve user productivity. According to a recent Gartner research half of the enterprise world says they intend to move to BYOD for smartphones alone by 2017, let alone other devices such as tablets, standard mobile phones and PCs. What are the steps taken by Brocade's Enterprise LAN switches to mitigate these issues?

Wired networks are dead. Long live wired networks.

by Rick Freedman on ‎07-03-2014 06:10 AM - last edited on ‎10-23-2014 01:25 PM by Community Manager (2,037 Views)

The expansion of wireless networks in recent years has been phenomenal.  The rapidly growing use of smartphones, tablets and corporate acceptance of BYOD has forced businesses to offer wireless connectivity virtually everywhere.  Pundits have forecasted the decline of the wired network as we know it and, perhaps, the demise of wired-only network companies. 

 

How then, can a network company that only makes wired network switches still be growing?  As with most technology companies, it requires a business to adapt and change, to survive and thrive.  The end-user connectivity may be changing, but the importance and dependence on the wired network has never been greater.

SDN Hybrid Mode: Connecting the Dots

by Simon Pollard on ‎06-10-2014 05:00 PM - last edited on ‎10-23-2014 03:14 PM by Community Manager (1,535 Views)

Combining all the elements of a modern IT infrastructure can often feel like solving a technological dot-to-dot puzzle; there aren’t any visible relationships between all the points that must be interconnected but when they are joined up they form a coherent picture. Every IT professional is painfully aware that the reality is somewhat different; the relationship between the different components – network nodes, servers, storage and applications – runs deeper than mere connections;

Elastic Networks

One of the biggest challenges when designing any new system that requires an element of capacity planning – computing, networks, transportation, to name a few - is deciding what the primary criteria are; should you go for a big initial costly build-out and hope that all of the capacity is used? Or aim for something more flexible that can start smaller and be expanded as required to deliver greater capacity. Factors such as the need for up-front investment and sketchy predictions of future demand need to be considered and the result can sometimes be a difficult compromise.

SDN Killer Apps for the Campus

by Jeff Sejourne on ‎05-16-2014 06:22 PM - last edited on ‎10-23-2014 03:27 PM by Community Manager (2,140 Views)

The data center is getting all the SDN attention these days, but the applications that will help SDN cross the chasm may actually very well come from the campus.

 

SDN has the ability to radically transform campus networks over the next few years and address today’s most acute management challenges.  Campus networks require application specific policies like security & access control, VLAN traffic isolation and QoS policies to be provisioned across the network one switch at a time. This consumes a lot of resources and results in a static network that cannot be easily updated as business requirements evolve and new applications are deployed.

by Jeff Sejourne on ‎04-16-2014 12:52 PM - last edited on ‎10-23-2014 03:30 PM by Community Manager (4,402 Views)

Since early last Wednesday, the web and media have been abuzz over a new security vulnerability they have named the Heartbleed bug. Heartbleed is a security vulnerability inOpenSSL, an open-source protocol primarily used to encrypt web communications but also used by IT personnel for connecting securely to network devices and servers for administrative purposes. After thorough investigation, our engineering teams have concluded that neither our products nor website are affected by the Heartbleed bug.

SLG CIO’s cite network infrastructure as critical to “Big Five” success

by Rick Freedman on ‎04-04-2014 02:18 PM - last edited on ‎10-23-2014 03:36 PM by Community Manager (1,898 Views)

The “Big Five” IT initiatives: 1) data center consolidation; 2) mobility; 3) security; 4) big data; and 5) cloud computing are gaining visibility and awareness for their promise to improve state and local agency performance, productivity and service.  However, a recent MeriTalk study and webinar on “The Big Five in Overdrive” demonstrate that while these solutions get a lot of attention, it’s the underlying network infrastructure needed to support these that is keeping CIOs awake at night.  The hot, new technologies get the visibility, but it’s the basics, blocking and tackling, where the real opportunity to re-engineer and save big comes from.

Leading the Road to SDN

by Rick Freedman ‎03-19-2014 05:15 PM - edited ‎03-19-2014 05:21 PM (2,705 Views)

Everyone seems to believe that Software Defined Networks (SDN) is the future.  They know it’s coming… whatever it is and whenever it gets here, but don’t really know what to do about it. 

 

We talked to hundreds of attendees at the Open Network Summit (ONS) in Santa Clara and the Aruba Airheads Developers Conference in Las Vegas over the past two weeks about our SDN strategy.  Most were familiar with the general concepts of SDN and knew what it is, at least in concept.  Some had ideas about what they might do with it… some day.  Few had specific plans to implement SDN or had even done any work with SDN yet.

 

What we learned was that Brocade is helping customers on the road to SDN with OpenFlow 1.3 and Hybrid SDN implementation to make the transition smoother.

Are State and Local Government Networks Ready for the Big Five of IT?

by Jeff Sejourne on ‎02-27-2014 12:34 PM - last edited on ‎10-23-2014 03:38 PM by Community Manager (2,043 Views)

A new Meritalk study, underwritten by Brocade, examines how the implementation of the Big Five of IT-data center consolidationmobilitysecuritybig data, and cloud computing – will affect state and local government.  According to the report, most state and local organizations plan to fully deploy the Big Five in the next three years, but almost all say their agency is not fully prepared for the resulting demands on the IT organization and the network infrastructure.

The study examines:

  • The potential combined network impact of the Big Five
  • The current state of readiness for state and local agencies
  • How agencies can take advantage of Big Five benefits without bottlenecks, downtime, and security risks

Scaling up vs. Scaling out:  for years, IT architects have been debating the respective merits of big box vs. multi-box solutions to achieve scalability.  Big box solutions can be simpler to deploy and manage but they are typically more expensive to acquire and offer limited upgradability and future proofing.  With the recent success of cloud computing, the question has been settled for compute and storage: only distributed multi-box architectures can achieve the level of scalability and availability required for cloud based applications.

Is managing your campus environment a high-wire act? IDC White Paper shows how to find the balance you need…

by Dawn.Morris on ‎10-28-2013 01:05 PM - last edited on ‎10-23-2014 11:47 AM by Community Manager (3,880 Views)

Is managing your campus network a bit of a daily headache?  Are you finding you have more not-spots than hot-spots in your wireless coverage? Do you find yourself have to explain (again) just why it is going to take “THAT long” to deploy that application?  The campus environment in many organizations has just not kept up with evolving trends, and the legacy networks are showing their age.  The “fixes” that have been deployed over time often make things worse rather than better, as complexity and cost go up, and overall performance and availability at best stay static.

The Effortless Network is about making campus networks fit the environment that they are being deployed into, making things simpler and more flexible by allowing network managers to build networks that are only limited by their imaginations. By using Ethernet as the connection medium within a switch stack we allow far greater deployment flexibility.

For campus networking, customers have been challenged with a convergence of trends that are forcing them to rethink their architectures and technology. For the last year or so, we’ve been saying that campus networks have moved beyond “best effort” and are now as critical as your datacenter network. While some early visionaries “get it”, many campus network architects have not….yet.

Taking the Network outside of the Wiring Closet with Enterprise Compact Switches

by Jeff Sejourne on ‎10-26-2013 02:31 AM - last edited on ‎10-23-2014 03:46 PM by Community Manager (1,857 Views)

So, what do you do when you need to convert an existing room into a conference room or a classroom where you are going to need more ports than what’s currently wired in the walls? Essentially, the network admin faces two options, deploy an enterprise switch inside the room or let users bring their own switches to solve the problem on their own as they often do. 

 

Deploying consumer class unmanaged switches in an enterprise network is a bad idea, the problems are numerous: no security, no quality of service, no traffic management, no monitoring, no visibility to the network administrator and the biggest of all, no spanning tree.  What if a user inadvertently creates a loop through improper wiring and brings part of the network down?

What is The True Cost of Your Campus Network?

by Jeff Sejourne on ‎09-29-2013 07:02 AM - last edited on ‎10-23-2014 03:49 PM by Community Manager (647 Views)

According to Gartner, enterprise customers  expect a useful life of 5 to 10 years for their network infrastructure.  Over such an extended ownership period the initial cost of acquisition is going to represent only a fraction of the total cost.

 

So it’s important for IT departments to evaluate the total cost of ownership, including the cost of service and support, power, cooling and floor space, over the expected life of the network when making the vendor selections.

Does Your BYOD = Bring Your Own Disaster?

by plaporte on ‎07-30-2013 08:21 AM (673 Views)

BYOD = Bring Your Own Disaster

 

For many enterprises, schools, or even Federal agencies; BYOD stands for Bring Your Own Disaster. After talking with lots of customers and partners, I can relate. By my anecdotal calculation, over half of all BYOD projects fail (a major Brocade partner swears it’s closer to 90%). The thing is, it doesn’t need to be that way. After attending numerous seminars, reading tons of papers and blogs, etc., and viewing vendor ads; you’d think BYOD was all about security. But it’s not!! And this is the trap that everyone falls into and is the main cause for failure.

 

Surprisingly, the solution is very simple –it just takes planning and focus. With careful planning and a focus on delivering a secure, high quality user experience as your guide post; you’ll see that BYOD is much more than just security. Yes. Security is a very important aspect but without forethought and planning for the impact BYOD will have on your infrastructure, you’re doomed to fail. You have to make sure your wireless and wired infrastructure can deliver the level of service your...

"You can't manage what you can't measure" is a quotation that we often hear thrown around the business world by people who forget that organizations are populated by human beings who can be somewhat unpredictable as they are often respond in ways are governed by what Human Resources professionals call “hygiene factors”, in other words, unpredictable things driven by emotion and instinct. KPIs are not the only answer to management headaches. I’m not suggesting that data and statistics have no part to play in managing modern IT systems just because they are used by irrational and unruly human beings, what is important is the interpretation of the data and the best decisions are made when we have the maximum amount of information available at our fingertips.

We are so used to, and so busy dealing with or working around, the complexity of our networks that sometimes we need reminding that it doesn't have to be this way.  Network complexity is an issue of the way legacy campus environments are designed.  It wasn't an inherently bad design when campus networks began to be deployed for the first time; it’s just that it isn't a design that could cope with the massive changes in scale, volume and mobility that have come into play since.
