Linux filels: creating, listing, updating, and more

There’s a lot more to working with files on Linux than creating, listing and updating them. After all, files can be Linux commands (i.e., binaries), scripts, images, simple text files, pointers to other files or folders. You might remember the "everything is a file" description of Unix and Linux systems.Even sockets and named pipes are files in their own way. Sometimes only the owner can see and use files, sometimes everyone can and sometimes select individuals will also have access. Here are some of the subtleties.Listing files Listing files on Linux is easy. You use the ls command. On the other hand, commands like ls, ls -l, ls -a and ls -ltr work very differently:To read this article in full, please click here

AMD unveils exascale data-center accelerator at CES

The Consumer Electronics Show (CES) might be the last place you’d expect an enterprise product to debut, but AMD unveiled a new server accelerator among the slew of consumer CPUs and GPUs it launched at the Las Vegas show.AMD took the wraps off its Instinct MI300 accelerator, and it’s a doozy.The accelerated processing unit (APU) is a mix of 13 chiplets, including CPU cores, GPU cores, and high bandwidth memory (HBM). Tallied together, AMD's Instinct MI300 accelerator comes in at 146 billion transistors. For comparison, Intel’s ambitious Ponte Vecchio processor will be around 100 billion transistors, and Nvidia’s Hopper H100 GPU is a mere 80 billion transistors.To read this article in full, please click here

Gigabyte spins off its enterprise business to better serve enterprises

Gigabyte has split in two, breaking off its enterprise business as a subsidiary called Giga Computing Technology that's focused on sales and support for its data-center products.The Taiwanese company is well known for its motherboards and GPU cards for gaming, but also for several form factors of servers. Breaking out Giga Computing into a separate unit enables it to better cater to the needs of enterprise customers, according to Daniel Hou, CEO of the new business. “This is just another extension of our long-term plan that will allow our enterprise solutions better react to market forces and to better tailor products to various markets,” Hou said in a statement.To read this article in full, please click here

Microsoft to acquire Fungible for augmenting Azure networking, storage

Microsoft on Monday said it is acquiring composable infrastructure services provider Fungible for an undisclosed amount in an effort to augment its Azure networking and storage services.Microsoft’s Fungible acquisition is aimed at accelerating networking and storage performance in datacenters with high-efficiency, low-power data processing units (DPUs), Girish Bablani, corporate vice president, Azure Core, wrote in a blog post.  Data processing units or DPUs are an evolved format of smartNIC that are used to offload server CPU duties onto a separate device to free up server cycles, akin to hardware accelerators such as graphics processing units (GPUs) and field-programmable gate arrays (FPGA).To read this article in full, please click here

Work from home is here to stay, so how should IT adjust?

The pandemic has changed how we work, probably forever. Most employees with jobs that can be done effectively from home have no intention of returning full time to the office. They find that their work-life balance is much more balanced without the long commutes and constant interruptions that accompany office work.According to a McKinsey/Ipsos survey, 58 percent of American workers had the opportunity to work from home at least one day a week in 2022, while 38 percent were not generally required to be in the office at all.To read this article in full, please click here

Former VMware exec Gillis resurfaces to run Cisco security business (again)

Industry veteran Tom Gillis, who left VMware in December, has returned to Cisco in a new but familiar role: senior vice president and general manager of Cisco’s Security Business Group. From 2007 to 2011, Gillis was vice president and general manager of Cisco’s then-called Security Technology Group, which focused on developing network, content and identity management products.After that, Gillis founded cloud computing firm Bracket Computing, which was acquired by VMware in May 2018.Gillis ran VMware's $2 billion networking and security business from that point until this past December, and he was responsible for a number of its core products, including VMware's NSX networking and network/edge software products. To read this article in full, please click here

Cloud providers should unify virtual networking and SD-WAN

I’ve predicted that virtual networks will be hot in 2023, but that begs the question of what exactly a “virtual network” is. One definition says, “not physically existing as such but made by software to appear to do so”, and that surely makes you wonder how businesses would be willing to commit to such a thing. Truth is, they already have, but I think it’s time to look closely at the concept of virtual networks, and to categorize what exactly is going on there. Why look at something that isn’t real and only appears to be?  We’ll see.I could offer a lot of discussions on the early days of virtual network evolution here, but they’re probably as useless as a debate on where your lap goes when you stand up, an example of worthless effort I recall from a childhood book. Instead, let’s look at virtual networks from two directions—the user and the application—and see how those two directions are shaping virtual network technology, increasing its importance, and converging on a new network model overall.To read this article in full, please click here

IT supply issues have organizations shifting from just-in-time to just-in-case buying

The past three years have been an unprecedented period of disruption in the semiconductor industry. The Covid pandemic and ensuing lockdowns shut down manufacturing, there were interruptions in shipping, and then the war in Ukraine adversely impacted supplies of critical raw materials.The first half of 2022 saw 46% more supply chain disruptions than the first half of 2021, according to a research report released this fall by Resilinc, a supply chain resiliency company.To read this article in full, please click here

Arista floats its answer to the strain AI puts on networks

If networks are to deliver the full power of AI they will need a combination of high-performance connectivity and no packet lossThe concern is that today’s traditional network interconnects cannot provide the required scale and bandwidth to keep up with AI requests, said Martin Hull, vice president of Cloud Titans and Platform Product Management with Arista Networks. Historically, the only option to connect processor cores and memory have been proprietary interconnects such as InfiniBand, PCI Express and other protocols that connect compute clusters with offloads but for the most part that won’t work with AI and its workload requirements.Arista AI Spine To address these concerns, Arista is developing a technology it calls AI Spine, which calls for switches with deep packet buffers and networking software that provides real-time monitoring to manage the buffers and efficiently control traffic.To read this article in full, please click here

AI is coming to the network

AI-enabled management platforms and infrastructure are beginning to make their way into enterprise networks. I say “beginning” because despite lots of AI-washing marketing efforts over the last few years, a lot of what has been characterized as “AI-driven” or “powered by AI” hasn’t really materialized. It's not that these systems don’t do what the marketers say, so much as they don't do it in the way they imply.Even some tools that do truly employ AI in meaningful ways, and with visibly different results than are possible without it, don’t feel qualitatively different from what has come before. They may be better, for example by dramatically reducing the number of false positives in alert traffic, but not different.To read this article in full, please click here

Using the Linux locale command

The locale settings in Linux systems help ensure that information like dates and times are displayed in a format that makes sense in the context of where you live and what language you speak. Here's how to use them.NOTE: None of the commands described in this post will change your locale settings. Some merely use a different locale setting to display the response you might be seeing from a different location.List your settings If you’re in the US, you should see something like this when you use the locale command to list your settings:$ locale LANG=en_US.UTF-8 LC_CTYPE="en_US.UTF-8" LC_NUMERIC="en_US.UTF-8" LC_TIME="en_US.UTF-8" LC_COLLATE="en_US.UTF-8" LC_MONETARY="en_US.UTF-8" LC_MESSAGES="en_US.UTF-8" LC_PAPER="en_US.UTF-8" LC_NAME="en_US.UTF-8" LC_ADDRESS="en_US.UTF-8" LC_TELEPHONE="en_US.UTF-8" LC_MEASUREMENT="en_US.UTF-8" LC_IDENTIFICATION="en_US.UTF-8" LC_ALL= The en_US.UTF-8 settings in the above output all represent US English.

Creating and removing directory structures on Linux

Managing directories on Linux is easy, but the process gets more complex when you need to create, empty or remove large, complex directory structures. This post will take you from the most basic commands to some fairly complex ones that can help make the process easier.mkdir The mkdir command can create a single directory like this:$ mkdir newdir It can also create a complex directory and subdirectory structure with a command like the one below. The -p argument tells the command to create the base directory if it doesn't already exist.Each group of directory names that appears in the command shown – like {1,2,3} and {docs,script} – will result in a series of subdirectories being created at that level.To read this article in full, please click here

What is Wi-Fi and why is it so important?

The term Wi-Fi was created more than two decades ago as a way to make local wireless networking easy to understand for the general public. Today, Wi-Fi technology is ubiquitous, making home and office connectivity without wires available for all, and contributing to an explosion of smart devices.What is Wi-Fi?  Wi-Fi is a blanket term for multiple technologies that use the IEEE 802.11 communications standards to create local area networks or LANs. Wi-Fi-enabled products use radio waves to transmit data and communicate with one another. Initially the technology used the 2.4 GHz frequency, but it has since expanded to 5 GHz, 60 GHz, and 6 GHz frequency bands.To read this article in full, please click here

Server supply chain undergoes shift due to geopolitical risks

Geopolitical tensions among the US, China, and Taiwan are forcing a notable change to server manufacturing, according to Asian market research firm TrendForce, which predicts that core parts of the server supply chain will eventually shift to southeast Asia and the Americas. According to TrendForce’s research, Taiwan-based original design manufacturers (ODM) currently account for about 90% of global server motherboard production. A notable exception is Supermicro, which has a 1.5 million square-foot factory in Fremont, California. It also has an 800,000 square-foot facility in Taiwan.Ever since the start of the trade dispute between the US and China beginning in 2018, server ODMs began looking at moving their production lines from mainland China to Taiwan. Then, due to the explosion in construction of data centers across the Asia-Pacific region, motherboard makers began looking at southeast Asian countries such as Malaysia and Thailand for capacity expansion.To read this article in full, please click here

What is a VPN? A secure network over the internet

VPNs date back to the 1990s when the public internet lacked almost any form of security, and the technology was developed to provide secure and cost-effective connections across this insecure landscape.VPNs have become widely deployed across enterprise networks and experienced a surge during the pandemic, when companies had to scramble to provide secure remote access to employees who were suddenly working from home.VPNs remain popular today, but they are also slowly but surely being supplanted by more flexible, more secure, more granular alternatives, such as SD-WAN, Zero Trust Network Architecture (ZTNA), and SASE, a cloud-based service that includes SD-WAN, ZTNA and other security features.To read this article in full, please click here
