The latest PCI Express (PCIe) specification again doubles the data rate over the previous spec.PCI Express 7.0 calls for a data rate of 128 gigatransfers per second (GT/s) and up to 512 GB/s bi-directionally via x16 data lane slot (not every PCI Express slot in a PC or server uses 16 transfer lanes), according to PCI-SIG, the industry group that maintains and develops the specification.

The slower, previous spec, PCI Express 6.0 has yet to come to market, and doubling the rate with each version has become the norm.To read this article in full, please click here
Cisco has announced plans to formally exit Russia, winding down its business operations in Russia and Belarus in response to the invasion of Ukraine earlier this year.The networking company first made a statement on March 3, declaring that it would be halting all business operations in Russia and Belarus "for the foreseeable future." On Thursday the company released another statement, noting that it had continued to "closely monitor" the war in Ukraine and as a result, a decision had been made to "begin an orderly wind-down of our business in Russia and Belarus."To read this article in full, please click here
By: John Gray, Data Center Marketing Lead, Aruba, a Hewlett Packard Enterprise company.Enterprises today know the world has changed, and they must change with it, especially in the ways they approach improvements to business process through the network.They want to choose and build the right capabilities to centrally host applications and data in distributed locations and, they want to connect their employees, devices, and resources the way they need to limit disruption and flex operations for growth.The answers are found at the intersection of the hybrid cloud and next generation data centers, technology that transforms IT operations and organizations.To read this article in full, please click here
Private 5G networks promise to offer low latency, high reliability, and support for massive numbers of connected devices, but enterpise deployment has been slower than expected, experts say, due to the pandemic and a slow-to-evolve device ecosystem.IDC reports that the global private LTE and 5G wireless infrastructure market totaled $1.8 billion in revenue in 2021 and will increase to $8.3 billion by 2026, but that spending will grow "slower than expected" in the next couple of years.To read this article in full, please click here
Organizations exploring the use of data-processing units (DPU) and infrastructure processing units (IPU) got a boost this week as the Linux Foundation announced a project to make them integral to future data-center and cloud-based infrastructures.DPUs, IPUs, and smartNICs are programmable networking devices designed to free-up CPUs for better performance in software-defined cloud, compute, networking, storage and security services.To read this article in full, please click here
The Edge Secured-core, program is designed to validate IoT devices for specific security hardware technology, and ensure users that they are running an OS with built-in security technology.
Have you ever wondered how many days it’s been since you started your diet, begun your daily jogs, or were first working with Linux? If you can remember the start date, a simple Linux script can count the days for you. All you need is the date command and a calculation that turns your dates into seconds, subtracts the start date from the end date and then divides the result by the appropriate number to turn the seconds into the corresponding number of days.Why seconds?
The reason for the conversion to days is that the date command can display a date as the number of seconds since the start of the Linux epoch—10=970-01-01. This is the only option date provides for looking at the time difference between two calendar dates.To read this article in full, please click here
AWS is making a push into an area of quantum computing that hasn't received as much attention as other aspects: networking.The AWS Center for Quantum Networking (CQN) will work toward solving scientific and engineering challenges around creating new hardware, software, and applications for quantum networks, AWS stated. The center will expand other AWS quantum work being done at the vendor’s AWS Center for Quantum Computing, the Amazon Quantum Solutions Lab, and its Amazon Braket service.

StorONE has introduced what it claims is the first storage platform to enable connectivity between standard mechanical hard disk drives (HDD) and flash drives over NVMe-over Fabric (NVMe-oF) infrastructures, which it says can reduce the cost of an NVMe solution by tenfold or more.Storage arrays have traditionally been separated by drive make. You have all-flash arrays and all-hard-disk arrays but not a mix of the two. Typical operation is to put “hot” data, or data that is frequently accessed, on the much faster SSDs, and put less frequently accessed data on the slower HDDs. That approach requires two or more separate arrays, plus the connection between them.To read this article in full, please click here
The Tuesday outage took just under two hours to fix, and follows similar disruption last week that caused network performance issues across India, Indonesia and Eastern Europe.

Cisco is prepping its high-end data-center Nexus switch family for high-speed Ethernet that will better support high-bandwidth applications such as AI and cloud-native. The vendor rolled out five new Nexus data-center switches that include improved support for 100/400Gb Ethernet networks, but its flagship box—the 9800—now includes a migration path to support 800GbE requirements.

The new modular data-center switch product family with 14.4Tb/s fully encrypted bandwidth per slot. The Cisco Nexus 9800 Series features eight-slot and four-slot chassis that can scale from 57Tb/s to 115Tb/s with a combination of various first-generation line cards and fabric modules. Each line card slot can support 400GbE or 100GbE or 10/25/50GbE ports. The eight-slot option could support up to 288 400GbE ports, well above the current 9000’s 32-port capacity.To read this article in full, please click here
AMD is working on an accelerated processing unit that will outperform its current top APU that powers the world’s first exascale supercomputer.At its recent analyst day, the company introduced a new high-end accelerator, the Instinct MI300, an APU that combines Zen 4 CPUs, the latest generation of GPU technology, plus AMD’s Infinity Cache and Infinity architecture in one package. It will deliver eight times the AI performance of AMD’s current high-end ACU, the MI250, and will be available next year.A pool of high-bandwidth memory on the ACU is shared between the CPU and the GPU allowing them to communicate freely without the performance or energy overhead of redundant memory copies.To read this article in full, please click here

The awk command can make it easy to remove duplicate characters from a string even when those characters aren’t sequential, especially when the process is turned into a script.First, the awk command that we’ll be using starts by running through each letter in the string. In a more common command, you might see awk doing something like this:$ echo one:two:three | awk ‘BEGIN {FS =":"} ; { print $2 }’

Or customers can keep their workloads as written and re-platform them to AWS with minimal code changes, AWS stated.To read this article in full, please click here
While it's one of the best tools for examining performance on Linux, htop still requires some explanation before you'll be ready to take advantage of all the data it displays. It’s an excellent tool, but you need to understand the coloring scheme, how to scroll up and down through the processes displayed, and how to change your view of what’s happening on the system.It may take some time to get used to the type of information shown and be ready to quickly notice performance problems. That, of course, means that you have to know what normal behavior looks like on your system, and this generally requires spending time with the tool on a relatively frequent basis. In other words, use htop when you’re not at all concerned about how your system is performing and you’ll likely be able to make good use of it when you are.To read this article in full, please click here
Intel has introduced a reference design it says can enable accelerator cards for security workloads including secure access service edge (SASE), IPsec, and SSL/TLS.The upside of the server cards would be offloading some application processing from CPUs, effectively increasing server performance without requiring additional server rack space, according to Intel.
