Virtually Simple

By Dan O’Donnell

Live simple. What a nice concept. Our lives in the technology industry, however, seem to be all about conquering the complicated rather than pursuing the simple.

Mobility, virtualization, more data, faster links, new applications and increasing vulnerability all require complex and sophisticated systems to manage and protect networks. Virtualized Desktop Infrastructure growth is increasing bandwidth requirements. Appliances are becoming more specialized so more are required. Connecting the tools without impacting network availability and managing all the appliances at 10Gbps link speeds is now becoming its own specialty.

A Gartner report, “Emerging Technology Analysis: Hosted Virtual Desktops” says the number of virtual desktops worldwide will increase to 66 million by 2014. While this growth of virtual technology is efficient for businesses, it adds complexity to network and application management. The need for greater visibility into network performance and application performance will increase just as dramatically as the growth of network bandwidth and virtual desktops.

Boiling it all down, there is a need to pursue simplicity in this ever more complicated environment. Time spent chasing network issues when the problem is with an application is time wasted. Time spent drilling down through layers and layers of analysis on 10Gbps link traffic can be frustrating while clients are experiencing outages or response time issues. Resolving performance issues proactively and optimizing network performance are more worthy pursuits than troubleshooting problems.

A side note on the business perspective of simple proactive network management…A team focused on trouble shooting is considered a cost center. A team focused on improving network performance and IT ROI is considered a strategic asset to the company.

So, in pursuit of a simple answer, what about a unified system providing end-to-end performance visibility across the network, allowing quick isolation of the root cause of performance issues? What about a solution that solves complex application issues simply? What about a couple of simple tools that are easy to deploy and take only a few RUs of rack space? What about connecting all your 1Gbps links through a port aggregator rolling them up to a few high-speed links for consolidated management? What about proactive network management, resolving issues before the clients even notice problems?

The Network Critical AFS port aggregator and the Visual Networks VPM Xpress 10G combine to provide a complete yet simple solution for link aggregation, network and application management. The AFS and Xpress solution allows network managers in virtual environments, carrier and cloud networks an efficient, simple solution to proactive network and application management.

Simple is good. Follow the links below for more information:

Get Noticed in 2012

By: Dan O’Donnell

Remember Rodney Dangerfield, the comedian whose signature line was “I don’t get no respect.” Those with jobs in IT, Cyber Security, Networking and the like know the feeling. When things go right (which takes a lot of dedication, specialized knowledge and hard work) nobody notices. When things go wrong (which can happen no matter how hard you work to keep things humming) the entire company is screaming like a banshee on steroids. Suddenly, everyone knows your name.

Sales guys get noticed when they sell things. They get trips to Tahiti, awards and a lot of positive recognition. Marketing develops programs and ads that are creative and widely publicized. Engineering develops cool designs that turn into products everyone can see. Even the guys from Finance are always making charts and presentations to the CEO showing their ROI calculations and how to finance new projects.

How can IT and Networking demonstrate their positive contributions to the organization? The key is to look at your job in a new way. Categorize, quantify and report on your contributions. Network Security, for example, keeps bad things from happening that could ruin a company. Theft of confidential customer information, leakage of classified product designs, external hacks that slow or block system access are a few examples of bad things that the Network Security group helps prevent. When things go right these issues do not exist so it is hard to quantify the contributions. However, there are industry reports that track these trends that can be used to set baselines.

Using the Network Security example, a department head can develop a set of indices setting Key Performance Indicators based on industry norms for a variety of network and security metrics. Then correlate the economic impact of meeting and exceeding these metrics. What you will have is a report that shows the ongoing financial benefit that sound security practices and procedures can bring to the company every day. Remember, money not spent, is profit.

The idea here is to quantify and report on the positive contributions that are made every day. Take the technical jargon out of the reports. Resist the urge to discuss the benefits of dual stack routers for IPv6 conversion (save that for departmental meetings). The CEO is less interested in how you do it but keenly interested in the contribution to the bottom line. The CEO is a business person and his/her interest is shareholder return. Show that your ideas are necessary to protect the company brand, to create revenue, or to reduce risk and liability.

Finally, be proactive with these ideas. Develop your business oriented reports and ask for time to present. In 2012, resolve to take a quarterly trip in the elevator to the top floor. Show your value to the company. Perhaps, you too, will be on a plane to Tahiti with the Sales leaders.

The Year of the Tap

By: Dan O’Donnell

Welcome to 2012. As the technology parade winds its way down Main Street, pay attention to the little float called Tap and Access. It has been in the parade for a number of years but fresh flowers and new designs are causing a buzz in the curbside crowd.

During the last four years or so, there has been a quiet storm brewing in network monitoring solutions. The tap market has been growing dramatically. The primary driver for this architectural revolution has been broad market acceptance of taps as a permanent architectural element in network monitoring and management solutions.

Why are networks so universally transitioning from Span ports to tap solutions? Here are a few ideas:

• Too few Span ports – With the introduction of many specialized network appliances that all need 24/7 link access, there are not enough Span ports to go around
• In-Line Access – Many new security appliances provide network protection by taking immediate action to resolve threats. These appliances are installed risk-free on network links by connecting through reliable, hardware-based In-Line taps. This method of connecting active appliances is often called a “Virtual In-Line” connection.
• Data Switching and Port Aggregation – As link speed migrates from 100Mbps to 1Gbps to 10Gbps and beyond, there is an increasing need to aggregate multiple lower speed links up to higher end tools. Conversely, there is also a need to distribute core high speed access to multiple lower speed links. These port switching devices provide many sophisticated access features and take their input from taps on the links. This practice provides risk free fail-safe access to the links while the data switches manage and distribute the traffic.
• Next-Generation Firewalls (NGFW) – This will be a big, big, big transition for 2012. Next Gen Firewalls are ready for prime time. These new versions of firewalls are addressing the more sophisticated threat environment with higher level visibility and control and will be the perimeter security cornerstone of networks. The transition is underway now and the best practice for NGFW connectivity is using In-Line taps.

Network Critical, a global innovator of permanent, modular taps and high speed data switches, aggregators and load balancers, is leading the network access revolution. Tap solutions from simple access to complex aggregation and distribution architectures can be found in the Network Critical product portfolio.

As network operators develop plans for upgrading to NGFW, high speed port aggregation, In-Line security appliances and other specialized access applications, Network Critical will be supporting their access requirements.

Taps and access devices may not be the Grand Marshall of the technology parade in 2012, but the tap market may very well win the Sweepstakes Trophy for fastest growing support technology. Happy New Year!
