Tomorrow is the big day!

How fast time flies! Tomorrow ( August 10) is my JNCIE-DC lab day.

I spent last couple of days repeating my notes and labbing small optional topics like CoPP, ZTP, etc; and also familiar ones like CoS and MPLS L3VPN.

Today is the rest day. Fly to Amsterdam, drink a couple of beers and go to bed. Fortunately I’ve been there before, so no worries about how to find Juniper office and be late for the exam.

Plan for tomorrow: go to the lab and get the job done.

Be a Budget Hero with Docker Enterprise Edition

We recently started a multi-part learning series for SysAdmins and IT professionals called IT Starts With Docker. We started with the basics, covering container technology and Docker solutions for the enterprise. Now, we shift to the important question: Is it worth your time and your company’s investment to further explore Docker Enterprise Edition (EE)?

The resounding answer to that question is YES. IT teams who have adopted Docker EE are finding it faster and easier to deploy and maintain their applications, plus drive better infrastructure utilization, all without touching the underlying code. Developer teams are realizing productivity gains of their own by being able to onboard new developers faster, shortening the cycles from development to production, and elimination of the burdensome “it worked on my machine” problems.

Docker EE

Try the simple ROI calculator for yourself. It takes just a couple of minutes and allows you to estimate your own savings with Docker EE and how you can become the budget hero of your department. Then, register for our live webinar on Tuesday, August 15th, The Business Value of Docker, where we will outline how organizations like your own are saving 50% on their total costs with Docker EE.

Episode 9 – What Your Mamma Never Told You About OSPF

As a continuation of our deep dives into routing protocols, this episode of Network Collective takes a closer look at OSPF. What does graph theory, CAP theorem, and distributed databases have to do with routing? What exactly is that type 4 LSA for? What is OSPF really good for? These and other questions are discussed by our guests Russ White and Nick Russo.

IDG Contributor Network: How AI is transforming healthcare for the benefit of patients

The development of artificial intelligence has made staggering leaps forward in recent years, with products like Apple’s Siri and Amazon’s Alexa now dotting living rooms and businesses across the nation. While AI has wasted little time in shaking up the foundations of most established industries, the field of healthcare, in particular, stands to be fundamentally transformed by this burgeoning technology.So what exactly does the future of AI hold for the healthcare industry? How are doctors and industry insiders preparing themselves, and what might it mean for patients' futures?Harnessing the power of machines More and more prudent investors are realizing that emerging data analytics capabilities are only the start of a forthcoming revolution. As health records are increasingly digitized, doctors and nurses will find themselves capable of ordering AI programs to sift through huge swaths of data to find meaningful trends that lie below the surface. Machine learning and artificial intelligence are able to perfectly archive and retrieve even the most complex sets of data, often doing so with greater efficiency than humans.To read this article in full or to leave a comment, please click here

How Wi-Fi could get a boost from Li-Fi

Wi-Fi has had an enormous impact on mobile computing use, enabling employees to access corporate networks from anywhere and turning coffee shops into offices for independent workers. It also has its shortcomings, which is where a new standard, Li-Fi, could one day fill in the gaps, assuming it can make it to market.The trouble with Wi-Fi? It doesn’t travel far, especially through walls. It is notoriously insecure and easy to spoof by hackers. And even with the bandwidth increases over the years, an access point can be overwhelmed rather easily when too many people try to access it at the same time.+Related: Does MU-MIMO really expand Wi-Fi system capacity?+To read this article in full or to leave a comment, please click here

Building Intent Based Networking System


I've been unhappy with my creation-to-consumption ratio lately, which is the amount of time spent creating compared to amount of time spent consuming. Yes I spend time creating design documents, business proposals, system architecture, slides for both technical and non-technical content, product requirement documents, blog posts, and occasionally write simple codes, but much of my free time is spent consuming for Netflix, newspapers, Twitter, televised sports, Facebook, blogs, Medium, TV series, online courses and others.

You may say we need consumption as an input prior to creating. And I agree, consuming is fine if it is part of learning or research in order to create something. But creation must come first. So if I commit to create something, let's say a system design or even this blog post, I must start by starting the work first and whenever I feel some information is needed to add or validate the work only then I will consume new inputs to mix with the old ones and fuel creativity.

Tonight I'm sitting in front of my macbook, in an attempt to increase my creation-to-consumption ratio, by writing about building Intent-Based Networking System (IBNS). Let's start with problem definition.

iSCSI ESX Datastore

Due to close scare in my lab I decided to switch the datastore from a single onboard hdd to iSCSI. I use a WD MyCloud EX2 Ultra but there are a lot of more advanced NAS out there with a whole host of extra features. The WD is rather basic but is sufficient for my needs of partitioning it into a backup drive and an iSCSI drive. Since moving onto this I haven’t noticed any real performance degradation in my lab, its run over 1 Gig port.

Preview: Networking Field Day Exclusive with Aruba (HPE) – The 8400 core switch

 

aruba-game-has-changed

Back to Silicon Valley!

As a network type, it’s hard not to be excited when heading to a Networking Field Day event. I joined then NFD club by attending NFD14 and have been hooked ever since.

Not only is it an honor and a privilege to be invited to an NFD event, the personal relationships that are forged in the larger TFD community are some of the most valuable I’ve ever had in my career.

This go around we’ll be visiting Aruba (A Hewlett Packard Enterprise Company) in Santa Clara to deep dive on the newest addition to the Aruba product line – the 8400 core switch.

A new face in campus town – the Aruba 8400

It’s been a while since anything exciting happened in the world of campus networking. It’s a steady segment for most vendors but nothing disruptive has really happened in the last few years.

And that’s not incredibly surprising. For better or worse, as long as campus networks aren’t broken in most enterprises, they are often neglected in favor of the data center and cloudy pursuits.

Aruba is touting the 8400 to increase automation and visibility in the campus core – both are areas Continue reading

Tough times strike Lenovo’s data center business

Lenovo has done a bang-up job in taking over IBM’s old PC business and turning it into a rousing success. Or at least as much of a success as can be had in an era of declining PC sales. Its luck with the server business? Not so much.Lenovo picked up IBM’s x86 server business in 2014 after some grumbling and consternation from the government. It seemed the government and military had quite an installed base of IBM servers and wasn’t keen on the Chinese taking ownership of them. But the deal went through after some assurances. Looks like that was the least of their problems. According to Gartner, in the first quarter of 2017, Lenovo sales fell 16 percent and its market share dropped to just 5.8 percent. Lenovo was fifth, behind HPE, Dell EMC, IBM (which is only selling Power-based RISC systems and mainframes) and Cisco. In fact, Lenovo had been ahead of Cisco in terms of units sold. When you fall behind Cisco in servers, a business Cisco didn’t even enter until a decade ago, you have a problem. To read this article in full or to leave a comment, please click here
