Creating a mixed-mode Virtual Chassis Fabric (VCF)

In order to mix EX switches and QFX switches in the same VCF, you need to enable mixed-mode.   This requires all members of the VCF to reboot unfortunately:

{master:1}
imtech@sw0-24c> request virtual-chassis mode fabric mixed
fpc0:
--------------------------------------------------------------------------
Mode set to 'Fabric with mixed devices'. (Reboot required)

fpc2:
--------------------------------------------------------------------------
Mode set to 'Fabric with mixed devices'. (Reboot required)

fpc3:
--------------------------------------------------------------------------
Mode set to 'Fabric with mixed devices'. (Reboot required)

fpc1:
--------------------------------------------------------------------------
WARNING, Virtual Chassis Fabric mode enabled without a valid software license.
 Please contact Juniper Networks to obtain a valid Virtual Chassis Fabric License.

Mode set to 'Fabric with mixed devices'. (Reboot required)

Once you’ve cabled up your QSFP ports between the EX4300 you are adding and the QFX spines, you need to do the following:

Enable the VCF port on the QFX spine:

request virtual-chassis vc-port set pic-slot 0 port 48

Communities Can Own Their Internet Destiny

Imagine you wanted to have an Internet connection and someone decided that you had to wait an undefined amount of time (maybe a year, maybe 10 years) to get access. Would you find it fair? I wouldn’t!

Unfortunately, this is the situation that millions of people in remote communities around the world have to accept. They will have Internet access only when operators decide to give them access which can be in a decade or more. These people won’t enjoy all the benefits we are enjoying today for a long time. And as more and more services go online – and exclusively online – they will not get the services they used to have since the services have moved to a new place where they are not allowed to be.

This is happening because operators can’t expand everywhere at the same time; they have to choose where they go this year, then next year, etc. There are some places where they will never go because those places are not going to bring them money. Among those regions that operators will never choose to go, we find, sadly, are the poorest rural areas that desperately need the economic and development opportunities Continue reading

DDI is a critical component of IoT success

The Internet of Things (IoT) era has finally arrived, and businesses need to be prepared for a world where everything is connected.I’m an analyst so I’ll support my proclamation that IoT is here with data: There are currently 25 billion internet-connected devices, and that will double by 2020 and then grow to 80 billion by 2025. ZK Research However, there’s a more basic way of understanding where we are in the adoption cycle: IoT has become the norm, not the exception, according to companies I talk to. IT and business leader no longer look at me like I have three eyes when I say, “IoT.” In fact, in many conversations with them, the term IoT never comes up — yet they are connecting things. Companies are connecting more things because it makes their businesses run better, and over the next decade, this trend will accelerate.To read this article in full, please click here

Worth Reading: Hiding the DNS

Among all the working groups that met at IETF 100 in Singapore was the first meeting of the DNS over HTTPs Working Group (DOH). I wrote on a related topic of DNS privacy a little over a year ago, looking at the work at the time on the privacy-related topics of QNAME minimisation, DNS over TLS, and what I called then ‘Secure DNS over JSON’, which was a variant of DNS queries over HTTPS. In this article, I’d like to look in a little more detail at the efforts to hide the DNS behind HTTPS and put the work in the DOH Working Group into a broader perspective. —Geoff Huston @ APNIC

Faster Machine Learning in a World with Limited Memory

Striking acceptable training times for GPU accelerated machine learning on very large datasets has long-since been a challenge, in part because there are limited options with constrained on-board GPU memory.

For those who are working on training against massive volumes (in the many millions to billions of examples) using cloud infrastructure, the impetus is greater than ever to pare down training time given the per-hour instance costs and for cloud-based GPU acceleration on hardware with more memory (the more expensive Nvidia P100 with 16 GB memory over a more standard 8 GB memory GPU instance). Since hardware limitations are not …

Disaggregated Or Hyperconverged, What Storage Will Win The Enterprise?

It has been a long time coming, but hyperconverged storage pioneer Nutanix is finally letting go of hardware, shifting from being an a server-storage hybrid appliance maker to a company that sells software that provides hyperconverged functionality on whatever hardware large enterprises typically buy.

The move away from selling appliances was something that The Next Platform has been encouraging Nutanix to do to broaden its market appeal, but until the company reached a certain level of demand from customers, Nutanix had to restrict its hardware support matrix so it could affordably put a server-storage stack in the field and not …

The OSI model explained: How to understand (and remember) the 7 layer network model

When most non-technical people hear the term “seven layers”, they either think of the popular Super Bowl bean dip or they mistakenly think about the seven layers of Hell, courtesy of Dante’s Inferno (there are nine). For IT professionals, the seven layers refer to the Open Systems Interconnection (OSI) model, a conceptual framework that describes the functions of a networking or telecommunication system.The model uses layers to help give a visual description of what is going on with a particular networking system. This can help network managers narrow down problems (Is it a physical issue or something with the application?), as well as computer programmers (when developing an application, which other layers does it need to work with?). Tech vendors selling new products will often refer to the OSI model to help customers understand which layer their products work with or whether it works “across the stack”.To read this article in full, please click here

The Journey to 150,000 Containers at PayPal

PayPal is committed to democratizing financial services and empowering people and businesses to join and thrive in the global economy. Their open digital payments platform gives 218 million active account holders the confidence to connect and transact in new and powerful ways. To achieve this, PayPal has built a global presence that must be highly available to all its users: if PayPal is down, the effects ripple down to many of their small business customers, who rely on PayPal as their sole payment processing solution.

PayPal turned to Docker Enterprise Edition  to help them achieve new operational efficiencies, including a 50% increase in the speed of their build-test-deploy cycles. At the same time, they increased application availability through Docker’s dynamic placement capabilities and infrastructure independence; and they improved security by using Docker to automate and granularly control access to resources. On top of the operational benefits, PayPal’s use of Docker empowered developers to innovate and try new tools and frameworks that previously were difficult to introduce due to PayPal’s application and operational complexity.

Meghdoot Bhattacharya, Cloud Engineer at PayPal, shared the journey his team has helped PayPal undertake over the course of the past two years to introduce Docker in Continue reading

BrandPost: Enterprises and Carriers in Sync with NFV

Historically, there’s always been tension between enterprises and carriers over equipment and servicing issues. But network functions virtualization (NFV) is providing more visibility into the network, giving enterprises greater confidence in what they’re paying for.Back in 2009, a survey by consulting firm EY found deep skepticism among enterprise users regarding telecom service providers. More than half of those surveyed at that time would not consider telcos for IT help desk, business consulting or cloud services.To read this article in full, please click here
