IDG Contributor Network: Pain relief for hospitals managing IoT performance

Nowhere is there more pain for IT staff than in the ever-morphing healthcare market where the Internet of Things (IoT) has been gaining attention and traction.The concept of IoT involves the use of electronic devices that capture or monitor data and are connected via wireless to a private or public cloud, enabling them to automatically trigger certain events. In the healthcare context, a growing set of IoT devices have been introduced to patients and medical staff in various forms. Whether wireless bedside monitors, infusion pumps, or even voice/data-based clinician communication devices, the result is means better and more efficient patient care.To read this article in full, please click here

The problem of unpredictable interface order in multi-network Docker containers

Whether we like it or not, the era of DevOps is upon us, fellow network engineers, and with it come opportunities to approach and solve common networking problems in new, innovative ways. One such problem is automated network change validation and testing in virtual environments, something I’ve already written about a few years ago. The biggest problem with my original approach was that I had to create a custom REST API SDK to work with a network simulation environment (UnetLab) that was never designed to be interacted with in a programmatic way. On the other hand, technologies like Docker have been very interesting since they were built around the idea of non-interactive lifecycle management and came with all API batteries already included. However, Docker was never intended to be used for network simulations and its support for multiple network interfaces is… somewhat problematic.

Problem demonstration

The easiest way to understand the problem is to see it. Let’s start with a blank Docker host and create a few networks:

docker network create net1
docker network create net2
docker network create net3

Now let’s see what prefixes have been allocated to those networks:

docker network inspect -f "{{range .IPAM.Config }}{{.Subnet}}{{end}}"  Continue reading

ChatOps – more Ops?

In the recent years we observed several movements inside of Corporate IT – DevOps and NetOps are two big ones in my experience. Probably there are more. While the definition of those is constantly changing depending on who you talk to and what time of day. Recently I came across a new term – ChatOps. […]

Show 379: Grappling With Promise Theory

Mark Burgess, who developed the principles of Promise Theory as a way to model distributed systems, joins the Packet Pushers to explore how his ideas connect to networking and information systems. The post Show 379: Grappling With Promise Theory appeared first on Packet Pushers.

It’s been said that software is “eating the world.” More and more, critical systems that were once controlled mechanically, or by people, are coming to depend on code. This was perhaps never clearer than in the summer of 2015, when on a single day, United Airlines grounded its fleet because of a problem with its departure-management system; trading was suspended on the New York Stock Exchange after an upgrade; the front page of The Wall Street Journal’s website crashed; and Seattle’s 911 system went down again, this time because a different router failed. The simultaneous failure of so many software systems smelled at first of a coordinated cyberattack. Almost more frightening was the realization, late in the day, that it was just a coincidence. —James Somers @The Atlantic

The charges, and the confirmation that the Russians had used social media in an attempt to influence the 2016 election, is likely to fuel the call for government regulation of Twitter, Facebook and other social media outlets. When tweets and posts can hurt democracy, America should do something, right? Wrong. —Paul Levinson @Connecting

As we start to connect durable goods such as cars, medical devices, and electricity meters to the Internet, Continue reading

U.S. Exascale Efforts Benefit in FY 2019 Budget

There was concern in some scientific quarters last year that President Trump’s election could mean budget cuts to the Department of Energy (DoE) that could cascade down to the country’s exascale program at a time when China was ramping up investments in its own initiatives.

The worry was that any cuts that could slow down the work of the Exascale Computing Project would hand the advantage to China in this critical race that will have far-reaching implications in a wide range of scientific and commercial fields like oil and gas exploration, financial services, high-end healthcare, national security and the military. …

NSX Layer 2 VPN: Deploying for datacentre migrations

In my previous post, NSX Layer 2 VPN: Migrating workloads between Datacentres, I described the process and theory behind using an NSX Layer 2 VPN (L2VPN) to migrate workloads from a soon-to-be-retired VLAN backed datacentre, to an NSX Managed logical switch backed datacentre. In this post I will take you through the deployment of the L2VPN in my lab environment, following these high-level steps:

  • Prepare the NSX Managed Site
  • Deploy the Layer 2 VPN Server
  • Prepare the Standalone Site
  • Deploy the Layer 2 VPN Client
  • Validate the Layer 2 VPN connectivity

Current lab environment

The Lab environment I am using currently reflects the diagram below, with two VMs deployed onto VLAN 20 within my “remote” site (my remote site is actually just a separate cluster from my “NSX Managed Site”, which is my workload cluster). In my NSX Managed site I have a Provider Logical Router (PLR) and Distributed Logical Router (DLR) configured.

Current lab layout

Current lab layout

Configure the NSX Managed Site

To prepare the NSX Managed Site the L2VPN-Server needs to be connected to a “trunk” interface, which allows multiple VLAN or Logical Switches to be configured as sub-interfaces, rather than having an interface in each VLAN/Logical Switch.

OpenACC Developments: Past, Present, and Future

On today’s episode of “The Interview” with The Next Platform we talk with Doug Miles who runs the PGI compilers and tools team at Nvidia about the past, present, and future of OpenACC with an emphasis on what lies ahead in the next release.

Over the last few years we have described momentum with OpenACC in a number of articles covering everything from what it means in the wake of new memory options to how it pushes on OpenMP to develop alongside. Today, however, we take a step back with an HPC code veteran for the bigger picture and …
