Sustainability goals drive data-center purchases

Data center operators are weighing new approaches to thermal management as they deal with growing compute requirements and strive to achieve sustainability goals. They’re not alone in prioritizing sustainability: Enterprise IT buyers are increasingly looking for data centers with sustainability credentials and are making purchasing decisions based on the presence of practices that reduce greenhouse gas emissions.That’s the crux of findings from research and advisory firm Omdia, which last week unveiled its Data Center Thermal Management and Sustainability Intelligence Service. The service is aimed at analyzing sustainable data-center best practices and strategies, with a focus on new technologies such as liquid cooling and energy storage systems.To read this article in full, please click here

Rocky Linux 9 arrives with Peridot

Release 9 of Rocky Linux just made its public appearance on July 14, and the big news is something called Peridot, which anyone (yes, anyone) can use to reproduce Rocky Linux 9 from scratch on their own. This is a truly exciting turn for the Linux community.If you’re not familiar with Rocky Linux, don’t be too surprised that it made it to Release 9 and you’re just now tuning in. “Release 9” doesn’t mean that Rocky has gone through eight prior major releases. Instead, the name indicates its connection to RHEL 9. Rocky Linux began life as Release 8.3 in April 2021 as a replacement for CentOS, which was EOL’ed in December 2020.To read this article in full, please click here

Cloudflare deployment in Guam

Having fast Internet properties means being as few milliseconds as possible away from our customers and their users, no matter where they are on Earth. And because of the design of Cloudflare's network we don't just make Internet properties faster by being closer, we bring our Zero Trust services closer too. So whether you're connecting to a public API, a website, a SaaS application, or your company's internal applications, we're close by.

This is possible by adding new cities, partners, capacity, and cables. And we have seen over and over again how making the Internet faster in a region also can have a clear impact on traffic: if the experience is quicker, people usually do more online.

Cloudflare’s network keeps increasing, and its global footprint does so accordingly. In April 2022 we announced that the Cloudflare network now spans 275 cities and the number keeps growing.

In this blog post we highlight the deployment of our data center in Hagatna, Guam.

Why a blog about Guam?

Guam is about 2,400 km from both Tokyo in the north and Manila in the west, and about 6,100 km from Honolulu in the east. Honolulu itself is the most remote major city in Continue reading

Automation 16. How to Prepare Cisco Nexus 9000 (Cisco NX-OS) to Be Automated with NETCONF and GNMI. Complete Guide.

Hello my friend,

When I booted up my laptop in the morning I was aiming to write something simple and easy: it is a summer and I don’t want to spend the whole Sunday on writing a blogpost. However, the topic, which is supposed to be an easy ride, appeared to be a bit more complicated. Well, it is even better then, as the official documentation to the topic is unfortunately vague.

Shall I use NETCONF or GNMI for automation?

The answer to this question, as usual, it depends. The first fact to think about is whether your platform supports any of these protocols. For example, the platform we will talk about today started supporting GNMI relateively recently and, to my surprise, it supports quite a legacy version of GNMI. At the same time, NETCONF, being an older technology compared to GNMI, are supported more robust. On the other hand, there are platforms, such as Nokia Continue reading

BGP Communities part 4: Active/Active datacenter

If you read part 2 of this series and came out wondering this is great but:

How do I connect to the internet?
Does this breakdown once I need to have connections?
What else do I have to do to manage state?

We’ll set out to answer these questions and show how it works. There are some dependancies such as your provider supporting customer BGP TE communities as laid out in part 3.

This seems to be the elusive grail in enterprise networking that everyone wants but is unsure of where to start. Hopefully, a few of those questions have been answered throughout this series but be sure to understand what you’re getting into and that your team can support it before and after you leave.

The overall topology

We’ve got data center 1 (DC1) and data center 2 (DC2). They each have a connection to an internal router in ASN 60500. A lot of networks I come across have dedicated routers coming out of the DC to terminate internet connections and support full tables. These router usually only pass a default internally. I don’t have the full tables but instead copy the topology and pass a default into the Continue reading

Weekend Reads 072222

The Chinese regime and other malign actors are trying to exert their influence over global technological standards, but the UK government’s response has been “incoherent and muted,” a committee of MPs has warned.

Researchers have discovered a new attack technique that exploits the speculative execution feature of modern CPUs to leak potentially sensitive information from the kernel’s memory.

The findings, which NJIT researchers will present at the Usenix Security Symposium in Boston next month, show how an attacker who tricks someone into loading a malicious website can determine whether that visitor controls a particular public identifier, like an email address or social media account, thus linking the visitor to a piece of potentially personal data.

Apple CEO Tim Cook has given his backing to a major effort to convince state governors, government, and educators to make computer science classes available to every student in every school. But it’s not just philanthropy in play.

Demand for smartphones is fading amid households’ fears about rising inflation and other monetary pressures, although brands including Samsung and Apple are weathering the economic storm.

In May 2022, 52% of business email compromise (BEC) scams impersonated third-party organizations, exposing businesses to supply chain attacks.

Is Automation A Full-Time Career?

This post originally appeared on the Packet Pushers’ now-defunct Ignition site on September 17, 2019. I have a lot of respect for people who focus on network automation and the people at Network To Code are top notch at helping and giving to open source. However, I do mostly disagree with this take on […]

Privacy And Networking Part 4: Logging

In the last post on this topic, I concluded that IP addresses are protected information—operators should handle users’ IP addresses according to privacy best practices. But I also concluded that because IP addresses used for forwarding— Are collected (or carried through the network) only for forwarding The user cannot reasonably expect the network to forward […]

All Problems Are Hardware Problems

When I was a lad in high school I worked for Walmart. I learned quite a bit about retail at my early age but one of the fascinating things I used in the late 1990s was a wireless inventory unit, colloquially known as a Telxon. I was amazed by the ability to get inventory numbers on a device without a cable. Since this was prior to the adoption of IEEE 802.11 it was a proprietary device that only worked with that system.

Flash forward to the 2020s. I went to Walmart the other day to look for an item and I couldn’t find it. I asked one of the associates if it was in stock. They said they could check and pulled out their phone. To my surprise they were able to launch an app and see that it was in stock in the back. As I waited for them to return with the item I thought about how 25 years of progress had changed that hardware solution into something software focused.

All problems start as hardware problems. If there’s a solution to an issue you’re going to build something first. Need to get somewhere fast? Trains Continue reading
