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 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
AMD continues to gain ground in the data center, grabbing CPU market share from leader Intel despite a significant decline in server processor shipments.Overall, the processor market took a hit in the fourth quarter of 2022, as well as for the full year 2022, due to lower demand, ongoing inventory corrections, and a slowing economy, according to analyst firm Mercury Research.For 2022, total unit shipments (client and server, excluding ARM) were 374 million and revenues came in at $65 billion, down 21% and 19%, respectively, compared to 2021.Specific to server processors, sales for the year came in at 36.1 million units, down 4.2% from 37.7 million in 2021. Revenues were $24 billion in 2022, down 7.7% from $26 billion in 2021. Mercury’s principal analyst Dean McCarron attributes the sharper drop in revenue versus units because the average selling price (ASP) declined.To read this article in full, please click here
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
5G connectivity is being used in a wide range of products, but one thing they have in common is that they tend to be very high-powered devices. Up until now, there has been little emphasis on low-power devices, such as small edge/IoT devices or consumer products.Qualcomm is addressing that with Snapdragon X35 5G Modem-RF, a 5G New Radio (NR) processor designed to serve the low-power and low-bandwidth markets.The company claims it is the first NR-Light processor based on the 2020 3GPP Release 17 spec that was written to support low-power 5G IoT devices over any of the broadcast frequencies allocated to 5G. At the same time, it is compatible with legacy LTE (4G). The spec is also known as “reduced capacity” or RedCap.To read this article in full, please click here
CDN (content delivery network) giant Akamai Technologies today announced that it will discount cloud egress pricing, add ISO, SOC 2 and HIPAA compliance, and build out enterprise-scale cloud computing sites and distributed points of presence in over 50 cities as part of a new initiative — dubbed Connected Cloud — aimed at filling a niche between the hyperscalers and edge computing.The idea is to fulfill what the company sees as unmet demand. In Akamai's view, modern applications are ncreasingly being broken into a range of different microservices. In many cases, those microservices need to be distributed across a geographically wide area, creating different computing needs than those addressed by most cloud vendors.To read this article in full, please click here
Observability may be the latest buzzword in an industry loaded with them, but Cisco will tell you the primary goal of the technology is to help enterprises get a handle on effectively managing distributed resources in ways that have not been possible in the past.The idea of employing observability tools and applications is a hot idea. Gartner says that by 2024, 30% of enterprises implementing distributed system architectures will have adopted observability techniques to improve digital-business service performance, up from less than 10% in 2020.“Today’s operational teams have tools for network monitoring, application monitoring, infrastructure monitoring, call monitoring, and more, but they rarely intermingle to provide a cohesive view of what’s going on across the enterprise,” according to Carlos Pereira, Cisco Fellow and chief architect in its Strategy, Incubation & Applications group.To read this article in full, please click here
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
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
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
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
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
