Data Center Switching ASICs Tradeoffs

A brief mention of Broadcom ASIC families in the Networking Hardware/Software Disaggregation in 2022 blog post triggered an interesting discussion of ASIC features and where one should use different ASIC families.

Like so many things in life, ASIC design is all about tradeoffs. Usually you’re faced with a decision to either implement X (whatever X happens to be), or have high-performance product, or have a reasonably-priced product. It’s very hard to get two out of three, and getting all three is beyond Mission Impossible.

Arista switches target low-latency, high-density networks

Arista Networks has rolled out two new switches that are designed to reduce network latency and decrease the need for cables and devices in high-density environments.The 7130LBR Series and 7130B Series are aimed helping customers consolidate servers, network and FPGA devices in Layer 1 networks that are typically found in financial, banking and trading environments along with certain enterprise environments such as those that support lots of video and test labs.

Making Flatpak Firefox use Private Browsing by Default

In April 2021 I wrote a post on making Firefox use Private Browsing by default, in which I showed how to modify the GNOME desktop file so that Firefox would open private windows by default without restricting access to normal browsing windows and functionality. I’ve used that technique on all my Fedora-based systems since that time, until just recently. What happened recently, you ask? I switched to the Flatpak version of Firefox. Fortunately, with some minor tweaks, this technique works with the Flatpak version of Firefox as well. In this post, I’ll share with you the changes needed to make the Flatpak version of Firefox also use private browsing by default.

When working with the non-Flatpak version of Firefox, the GNOME desktop file installed with the Firefox package is found at /usr/share/applications. In my earlier article, I suggested editing that file to add the --private-window parameter to the Exec line. Unfortunately, that change gets overwritten every time the Firefox package is updated. It’s better, actually, to use a locally customized desktop file placed in ~/.local/share/applications instead, which will take precedence over the shared desktop file.

With the Flatpak version of Firefox, there is still a shared Continue reading

‘Integration Tax’ Limits Network Automation

For every dollar spent on a new tech product, it costs several dollars to integrate that product. How can businesses overcome those costly obstacles that impede network engineering and ops teams' abilities to deploy new tech, like automation?

ISC ’22: The AMD-Intel-Nvidia HPC race heats up

The International Supercomputer Conference (ISC) kicked off in Hamburg, Germany this week with the release of the TOPP500 list of the fastest supercomputers, with a computer named Frontier taking first place.Deployed at the US Department of Energy’s Oak Ridge National Labs, it is the first exascale machine (1018 floating point operations per second)—an HPE-Cray EX system powered by AMD Epyc CPUs and Instinct MI250 GPUs.Intel had hoped to win the exascale battle with another DoE computer called Aurora, but AMD beat it to the punch. Frontier also beat out competitors from China and Japan that had hoped to win the exascale race.To read this article in full, please click here

Released: Automation content navigator 2.0

Automation content navigator releases with Ansible Automation Platform 2.2

 

What is it?

Automation content navigator was released alongside Red Hat Ansible Automation Platform 2.0 and changed the way content creators build and test Ansible automation. Navigator 1.0 drew together multiple Ansible command line tools like ansible-playbook, ansible-doc, ansible-config, etc. and continues to accrue seriously useful new features to help deliver greater flexibility to automation creators.

Coinciding with the release of Ansible Automation Platform 2.2, navigator 2.0 introduces improvements to existing functionality alongside additional features to aid in the development of automation content.

Within navigator 2.0, you will find:

• Automation execution environment image build support 
• Ability to interact in real-time with automation execution environments 
• Settings subcommand to view active configuration of local environment 
• Generate a sample configuration file that can be used for new projects
• Automatic mode selection (stdout vs. interactive) 
• Technology preview lint support, UI improvements, Collections view support for Ansible built-ins, time zone support, color enhancements, and more!
  
  

Looking closer

Image builder support

Before the release of navigator 2.0, a separate command line application (ansible-builder)  was needed to build execution environment images from human readable YAML files. With this release, ansible-navigator Continue reading

Thinking Outside the Box for Network Acceleration

There is a continued push to go even “faster.” Lowering port to port latency while maintaining features and increasing link speeds and system density is a significant technology challenge for designers and the laws of physics. Since the first release of Arista’s 7100 and 7150 switch families, the company has been a partner in building best-in-class low latency trading networks that are today deployed in global financial institutions and trading locations.

Cutting edge customers took the approach of disaggregating network functions into pools of functionality – extremely fast Layer 1 switching, operating as low as 5 ns and FPGA-driven trading pipelines running at under 40 ns with the Arista 7130 family. This approach allowed more sophisticated L2 / L3 networking functionality, such as the ability to tap any flow or enable routing protocols, to run on general-purpose systems, including the Arista 7050X, 7060X and 7170 full-featured platforms, using merchant silicon with billions of packets per second and low latency.

MLAG Deep Dive: System Overview

Multi-Chassis Link Aggregation (MLAG) – the ability to terminate a Port Channel/Link Aggregation Group on multiple switches – is one of the more convoluted¹ bridging technologies². After all, it’s not trivial to persuade two boxes to behave like one and handle the myriad corner cases correctly.

In this series of deep dive blog posts, we’ll explore the intricacies of MLAG, starting with the data plane considerations and the control plane requirements resulting from the data plane quirks. If you wonder why we need all that complexity, remember that Ethernet networks still try to emulate the ancient thick yellow cable that could lose some packets but could never reorder packets or deliver duplicate packets.

Juniper vMX on GNS3

Juniper Network has several products tha can be run on virtualization (hypervisor), such as KVM and ESXi. Those products include vMX (router), vSRX (firewall / security), vQFX (switch), and so on. The virtual Juniper products ease us to deploy it on lab or simulator, even on the production environment, which is run on the hypervisor. […]
