Server DRAM to exceed mobile DRAM, as enterprises adopt emerging tech

Semiconductor manufacturers will respond to changes in demand by producing more dynamic RAM (DRAM) for servers than for mobile devices this year, a milestone that highlights increasing enterprise use of emerging technology related to cloud computing, AI and high performance computing (HPC) applications, according to market research firm TrendForce.To handle the emerging-tech workloads, the average DRAM content of servers will increase by 12.1% year-over-year in 2023, compared to an increase of 6.7% for DRAM content for smartphones, TrendForce forecasts. DRAM content refers to the amount of DRAM memory installed in a device.In a related estimate, server memory chips this year are expected to make up 37.6% of what TrendForce determines to be the total bit output of DRAM semiconductors, compared to mobile DRAM’s 36.8%, the company said in its latest DRAM research report.To read this article in full, please click here

Oracle outages serve as warning for companies relying on cloud technology

Multiple Oracle Cloud Infrastructure (OCI) outages have hit users around the world this week, and coming after interruptions in Microsoft's cloud services last month, are a reminder of the importance of site engineering for systems administrators whose businesses rely on cloud-based mission critical applications.The biggest OCI outage this week began on 17:30 GMT Monday and stretched till Wednesday 22:30 GMT, impacting customers across North and South America, Australia, Asia Pacific, Middle East, Europe and Africa.“Oracle engineers identified a performance issue within the back-end infrastructure supporting the OCI Public DNS API, which prevented some incoming service requests from being processed as expected during the impact window,” the company said on its cloud infrastructure  website.To read this article in full, please click here

Cisco chips away at product backlog but challenges remain

Cisco is getting more products out the door, thanks to significant product redesigns and relentless efforts by its supply-chain team to address component shortages, but the situation is still challenging.“While components for a few product areas remain highly constrained, we did see an overall improvement in the supply chain,” said Cisco CEO Chuck Robbins during a call with financial analysts to discuss the vendor's second-quarter results. Cisco reduced its backlog 6% sequentially in the second quarter, however total backlog grew year over year, Robbins said, though he didn't cite an exact dollar figure. The company still expects to have a backlog that’s roughly double what it would normally be at the end of the year. (In February of last year, Cisco said its product backlog was valued at nearly $14 billion.)To read this article in full, please click here

Cisco streamlines SD-WAN hardware and software at the edge

Cisco is adding compute power and streamlining edge hardware and software offerings to make SD-WAN easier to deploy and manage.Taken together enhancements are aimed at helping to better handle growing distributed enterprises but also to help simplify environments—the hardware by allowing users to collapse multiple devices into one, and the software to ease configuration and management of SD-WANs.On the hardware side, Cisco is adding the 3U, Catalyst 8500-20X6C edge platform to its Catalyst 8000 Edge Platforms Family. It is an edge aggregation device built on the Cisco’s quantum-flow processor (QFP) ASIC and promises more than three times the performance over the existing high-end Catalyst 8500 Series Edge Platform, according to Archana Khetan, head of products in Cisco’s Enterprise Routing group. “With the increased power, customers can support more users and collapse the number of boxes they need to support edge applications as needed,” Khetan said.To read this article in full, please click here

Many ways to use the echo command on Linux

The echo command (a bash built-in) is one of the very basic commands on Linux. As with ls and pwd, you can't sit on the command line very long without using it. At the same time, echo has quite a few uses that many of us never take advantage of. So, this post looks into the many ways you can use this command.What is the echo command on Linux? Basically, echo is a command that will display any text that you ask it to display. However, when you type “echo hello”, the echo command isn't only spitting out those five letters, it's actually sending out six characters – the last one being a linefeed. Let's look at a couple of commands that make this obvious.To read this article in full, please click here

Network-as-a-service lets a shoe retailer take steps toward Zero Trust

Nigel Williams-Lucas, director of Information Technology at Maryland-based footwear retailer DTLR, faced a challenge that most IT execs will recognize: the business was pushing hard on digital transformation, and the IT infrastructure was struggling to keep pace.Store managers were seeking better data analytics and business intelligence from backend systems like inventory and sales. The business wanted IT systems to support customers ordering online and picking up at a physical store within two hours.The network needed to securely support real-time, bandwidth-intensive IP security cameras. And Williams-Lucas wanted to roll out beaconing technology, in which the network gathers information about customer in-store activity via Bluetooth or Wi-Fi, and can send discount offers to a customer’s phone based on where they are in the store and what they appear to be interested in.To read this article in full, please click here

Why network pros need a seat at the application-planning table

Over 90% of the network managers, executives, and planners I’ve interacted with in the last six months believe that they have little or no strategic influence on how their companies’ networks are evolving. That’s a pretty astonishing statistic, but here’s one that’s even more astonishing: Almost 90% of that same group say that their companies’ application cost overruns and benefit shortfalls were either predictable based on network behavior, or a direct result of mistakes that network professionals could have caught. It’s important for network professionals to get their seat back in those planning conferences, but it’s vital for their companies that they do so.To read this article in full, please click here

5G hits the streets of New York

With 56% of New York City households lacking both home and mobile broadband connections, a consortium is taking steps to supply at least mobile access via sidewalk kiosks, the latest of which include 5G.Called Link5G, these kiosks also provide free Wi-Fi access, a built-in tablet to access maps and other resources including phone connections, a USB-port to charge mobile devices, a jack for headsets, and a button to make 911 calls. Some also include two 55-inch screens for digital signage that can provide the city with ad revenue to help pay for the kiosks. Perhaps the most interesting feature, though, are the 5G cellular antennas near the top of the 32-foot structures.To read this article in full, please click here

Joining lines of text on Linux

There are number of ways to join multiple lines of text and change delimiters if needed. This article shows two of the easier ways to do this and explains the commands.Using the tr command The tr command is quite versatile. It’s used to make many types of changes to text files, but it can also flatten multiple lines into one by replacing newline characters with blanks. It does, however, remove the final newline as well. Note the $ prompt at the end of the second line. That's a clue!$ tr '\n' ' ' < testfile This is a file that I can use for testing. $ $ tr '\n' ' ' < testfile > newfile To fix this problem, you can add a newline to the end of the file with an echo command like this:To read this article in full, please click here

VMware ESXi server ransomware evolves, after recovery script released

After the FBI and the Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday released a recovery script for organizations affected by a massive ransomware attack targeting VMWare ESXi servers worldwide, reports surfaced that the malware evolved in a way that made earlier recovery procedures ineffective.The attacks, aimed at VMware’s ESXi bare metal hypervisor, were first made public February 3 by the French Computer Emergency Response Team (CERT-FR), and target ESXi instances running older versions of the software, or those that have not been patched to current standards. Some 3,800 servers have been affected globally, CISA and the FBI said.To read this article in full, please click here
