Stretching the Business of Tape Storage to Extreme Scale

IPOs and major investments in storage startups are one thing, but when it comes to a safe tech company investment, all bets are still on tape.

The rumors of tape’s death are greatly exaggerated, but there have been some changes to the market. While the number of installed sites might be shrinking for long-time tape storage maker, SpectraLogic, the installation sizes of its remaining customers keeps growing, which produces a nice uptick in revenue for the company, according to its CTO, Matt Starr.

This makes sense since the relatively smaller backups and archives make better performance sense on disk—and many …

Worth Reading: What if there is no money in systems?

Making money in the information technology market has always been a challenge, but it keeps getting increasingly difficult as the tumultuous change in how companies consume compute, storage, and networking rips through all aspects of this $3 trillion market. It is tough to know exactly what do to, and we see companies chasing the hot new things, doing acquisitions to bolster their positions, and selling off legacy businesses to generate the cash to do the deals and to keep Wall Street at bay. —The Next Platform

CCIE/CCDE Re-certification: An Opportunity to Learn and Grow

I did not pass my CCDE re-certification last week.  Why write a blog about a “failure”?  Honestly?  Because I think we as an IT industry overly focus and give too many kudos to the passing only.  Not to the hours and hours of studying and learning… not to the lessons learned… not to the growth gained from the studying journey.  Just to the “pass/fail”.  Well damn… no wonder people cheat.  Their focus isn’t on the learning or the journey.  Just the passing.

I thoroughly believe the expression –

Sometimes you win….. Sometimes you learn.

Did I want to pass last week?  ROFL!  Are you kidding?  Of course I did!  Did I “deserve” to pass?  Well…. um…. err… not exactly.

See that 10% at the bottom of the “Written Exam Topics v2.1?”   Truth be told I didn’t quite exactly study that part very much.

So what is my plan now?

LEARN

Honestly in my job I am not doing much Cloud, SDN, or IoT.  AND I have to admit I am quite happy I am now essentially forced to learn these to a Continue reading

Nokia rolls out its first ‘petabit-class’ router

With internet traffic set to triple over the next five years or so, according to recent estimates from Nokia and Cisco Systems, Nokia thinks the time is right for a new range of high-end routers that can boost core capacity by a factor of six—and even help 10-year-old devices to double their capacity.Nokia predicts that by 2022, total internet traffic will reach 330 exabytes per month. (That's 330 million terabytes). For its part, Cisco forecasts it will grow at 24 percent per year from a base of 96 exabytes per month in 2016 to 278 exabytes per month in 2021.That traffic growth will be driven by three things, according to Nokia: cloud services, 5G mobile networks, and the Internet of Things.To read this article in full or to leave a comment, please click here

Amazon transforms data into bricks

There’s been a lot of news lately about Amazon opening physical stores. These news articles keep interrupting my regular stream of stories about digital transformation. Or are these topics the same?Digital transformation involves using technology to improve performance and/or experience. The tool kit to do this is largely software-based and includes improved integration and workflow, analytics, mobility, social media and IoT devices.Due to Amazon.com's advantage in price and selection, the company has become a retailing behemoth at the expense of local retail. Store closures are about to hit a 20-year high, and malls are dying. This is unfortunate because retail centers provide more benefits than shopping. They are gathering places and contribute tax revenue for their municipalities.To read this article in full or to leave a comment, please click here

CCNA Wireless – CCNA Wireless Notes Chapter 6

802.11 Frame Format

In a wired Ethernet network, the switch is not an active participant in communication at L2. In a wireless LAN, the AP is an active participant unless something like 802.11z, Extension to Direct Link Setup (DLS) is used.

To direct frames through the AP, the radio must have a MAC address, known as the BSSID.

802.11 frames can carry a maximum payload of 2304 bytes.

To support wireless communication, the Ethernet frame format is quite different compared to wired networks. The Ethernet frame starts out with a 2-byte Frame Control field, identifying the frame type, the direction the frame is traveling in and more.

Name Length (bits)
Protocol Version 2
Type 2
Subtype 4
To DS 1
From DS 1
More Frag 1
Retry 1
Pwr Mgmt 1
More Data 1
WEP 1
Order 1

In a common scenario with multiple clients associated with an AP that is connected to an DS, frames travel from clients towards the DS or from the DS towards the clients.

The frame motion is indicated by two bits, To DS and From DS, in the Frame Control field.

Frames sent by a wireless client will Continue reading

Imagination adds safety, resilience to processor for IoT

Picture this: The networking stack on the main pump controller has crashed, and you need to reboot it -- but it's 20 meters underground, on another continent -- and there's no-one on site to hit 'reset'.Or you're bowling along the highway and one of the processor cores in your self-driving car gets zapped by a cosmic ray (yes, this could actually happen). The software can't tell whether the resulting error is a transient glitch or a hardware fault, so limits you to 50 kilometers per hour for safety: No fun with a monster truck hurtling up behind you.Chip designers such as ARM and Imagination Technologies are applying industrial safety design techniques to their processor cores so that they can get themselves out of situations like this. You could soon feel the benefit even if you don't run a subterranean pumping station in Azerbaijan, nor yet have a self-driving car in your garage.To read this article in full or to leave a comment, please click here

For Me the Internet Is Everything: Supporting Local Heroes in Armenia

Andranik, Sipan, Rudolf and Vahan have several things in common: they are young, they have dreams, they love music, and they love the Internet. The four of them are visual impaired. 

They met through the Internet Availability Center at the Cultural House of the Armenian Society of Blinds (ASB). 

I had the chance to visit the Center last year and Rudolf told me: “For me the Internet is everything. I cannot imagine what my life, my studies would be without it.”

Worth Reading: The next five years of IPv6

The qualities of this deployment seem to me (at least) to best fit a logistic supply curve. Why? Because the economics application is often to model the rate of uptake of innovation, where we know it starts low (or zero) and it winds up hopefully at 100%, but it can’t go on forever — there is a foreseeable endpoint that might not be approached. The early days are slow, then things hit a critical mass and it seems to explode into action, and then things tail off again as the market saturates. —APNIC
