Preserving Our Future, One Bit at a Time

“Culture, any culture… depends on the quality of its record of knowledge.” — Don Waters, “‘Preserving Digital Information”

Our culture and society has been enriched by the creation and proliferation of the Internet. Information has become increasingly more accessible and has enabled so many of us to become active creators rather than passive consumers of content. With that, we’re experiencing an explosive growth of digital data, with 2.5 quintillion bytes of data created every day and that data needs a place to live.

Not only does our data need a place to live, but it needs a place to survive into the future. What happens if years from now, we are no longer able to access our photos, documents, music — essentially all the records of our lives? We will not only be forgotten, but we’ll be thrusting the future into a “digital dark age,” as Vint Cerf calls it.

In short: “More and more of our lives are bound to the ones and zeroes of bits residing on a cloud server, or mobile device. Those bits in turn are mediated by the software and hardware implements we use every day. The bitstreams are unintelligible, however, without Continue reading

How Chuck Robbins is turning Cisco around

Cisco’s CEO, Chuck Robbins, is a busy guy. I never see him not talking to a customer, partner, employee, analyst or some other person in the company’s ecosystem. Over the holiday break, I hope he took the time to put his feet up, light a cigar and reflect on what’s happened to the company he is leading over the past two years.If we roll the clock back to Jan. 1, 2016, the stock was at $23.79, which was the lowest price point since April of 2014, and many Cisco investors were skeptical of Cisco’s future prospects.Read also: Cisco CEO Robbins: Wait til you see what’s in our innovation pipeline A hefty amount of my business comes from my interactions with Wall Street, and two years ago, very few wanted to talk about Cisco. There were far more bears than bulls, and the feeling was that the cloud, software-defined networking (SDN) and other trends would slowly eat away at Cisco and it would go the way of Lucent, Nortel and so many other companies that were too stubborn to change their business models.To read this article in full, please click here

Worth Reading: 2018-2019 Data Center Technology Trends

The data center technology evolution is going through an inflection point that will be very strongly driven during 2018/2019. Until now the industry was driving for cloud services centralization and transition of small and mid-sized enterprises to that cloud, I believe the next couple of years will show a change in the data center trends. It is very clear that all the mega data center operators will continue scale-out their data centers rapidly however that will just be a scale out effort not a technology change. While that massive scale-out effort is interesting to observe and be part of, the actual technology inflection point is not going to happen there in my opinion. —Yuval Bacher @ LinkedIn

Is single tenancy the fix for the Meltdown flaw?

As the fallout continues over the Meltdown and Spectre exploits in Intel and now some ARM processors, the issue of what to do about it is coming front and center. Clearly there is no fixing a silicon problem; Intel will have to adjust future chips to deal with it. So, for now, we have the software fixes.Linux distros are rolling out fixes, and Microsoft has issue patches for Windows — although the threat to consumers is minimal. Apple has also issued a macOS fix.To read this article in full, please click here

IDG Contributor Network: Key differences between the IoT and Industrial IoT you should know

It’s only the beginning of 2018, but the Internet of Things (IoT) has already once again seized the media and the market’s attention spans. Tech investors, aspiring entrepreneurs, and avid consumers of digital gadgets and software are wondering what the new year has in store for the IoT, and the smartest amongst them are beginning to ask questions.Perhaps the number one question that’s plaguing the mind of IoT onlookers is how to discern broader IoT trends from industry-specific ones, and few have more questions than those betting on the future of industrial IoT. So, what are the key differences between the IoT and Industrial IoT in particular, and what common myths should you be aware of?To read this article in full, please click here

BrandPost: Irresistible Appeal of Open Source

The telecom industry is racing toward a software-defined networking (SDN) world, but needs to go beyond traditional cooperation on standards to actually sharing software code, in order to keep pace with innovation.Telecom companies have always cooperated in development of standards. It’s essential for interoperability – otherwise each company’s customers would only be able to interact with its other customers. But there’s a difference between agreeing on standards and sharing software.“The telecommunications space has conventionally used proprietary hardware and software to deploy solutions from various vendors,” writes RCR Wireless staffer Nathan Cranford. “Using multiple vendors enabled telecom operators to open source some network functions, but not to the extent usually fastened to open source software.” But, he contends, “Open source software is indispensable to a faster, more malleable communications network.”To read this article in full, please click here

New Design on www.ipSpace.net

One of my readers sent me a polite email a while ago saying “your site is becoming like $majorVendor’s web site – every corner looks completely different based on when you made it”

BGP in 2017

This is a report on the experience with the Internet's inter-domain routing system over the past year, looking in some detail at some metrics from the routing system that can show the essential shape and behaviour of the underlying interconnection fabric of the Internet.

Salt Overview

Salt is open source software for infrastructure automation. Salt was initially an agent based system but the team have since implemented an ssh based connector for devices that do not support or have the ability to install an agent. This agent/agentless feature give you the ability...continue reading

MC-LAG

MC-Lag

 

Everyone  mostly know what MC-Lag does, for the benefit its a variant of LAG where the Down stream Devices share LAG interface on two Physical devices instead of One, I know its confusing let see a  sample topology

 

 

Vqfx1 will see the upstream as 1 ae1 instead of two different VMX devices, this has its own advantage and the entire discussion is something out of scope of this blog post.

 

Blog Post Goal – Demonstrate MC-Lag on VMX and Quickly highlight the options Common and different in MC-LAG, a ready reference for someone going for an exam or a implementation.

 

Take-Away’s

-> ICCP is the protocol between the nodes

 

  • Uses TCP/IP to replicates control plane and forwarding traffic between peers
  • One stand-by and one active (active responsible status control)
  • ICCP messages exchange configuration information to ensure both peers use correct LACP Parameters
  • ICL-PL (interface between Mx1 and Mx2 ex) supports Multiple MC-Lag Between the peers so its recommended to be a AE.

 

-> ICL-PL HA

 

  • A Keep-alive message is exchanged between MC-LAG peers which is recommended to be the management connection
  • If ICL-PL fails, keep alive is still through the management Continue reading

VMware Cloud on AWS with NSX: Communicating with Native AWS Resources

If you haven’t already, please read my prior two blogs on VMware Cloud on AWS: VMware SDDC with NSX Expands to AWS and VMware Cloud on AWS with NSX – Connecting SDDCs Across Different AWS Regions; also posted on my personal blog at humairahmed.com. The prior blogs provide a good intro and information of some of the functionality and advantages of the service. In this blog post I expand the discussion to the advantages of VMware Cloud on AWS being able to communicate with native AWS resources. This is something that would be desired if you have native AWS EC2 instances you want VMware Cloud on AWS workloads to communicate with or if you want to leverage other native AWS services like AWS S3 VPC Endpoint or RDS.
