BrandPost: Three Ways SD-WAN and Networking-as-a-Service Benefit Sustainability and ESG

By: Gabriel Gomane, Senior Product Marketing Manager, Aruba, a Hewlett Packard Enterprise company.Environment, social, and governance, or ESG, has become a hot topic in corporate strategy as a key component to driving shareholder value and interest. Sustainability, in particular, is often considered the main focus to attain ESG goals due to growing climate change concerns. That strategy, however, must look beyond traditional methods and expand to encompass IT and corporate computing practices, which in turn can drive a significant chunk of an organization’s carbon footprint through its vast energy needs.In a recent Gartner survey, CEOs considered environmental sustainability as a key differentiator and placed environmental sustainability in the top 10 strategic business priorities. Additionally, 74% of CEOs agreed that increasing Environmental, Social and Governance (ESG) efforts attract investors toward their companies[1].To read this article in full, please click here

IDC: With possible recession looming, IT pros plan spending adjustments

Facing what they perceive as an inevitable recession, IT planners are moving ahead with infrastructure investment but also calculating how to shift priorities if spending cuts become unavoidable, according to monthly surveys by IDC.Roughly 81% of respondents expect their spending to stay the same or increase for 2023, despite anticipating economic “storms of disruption." The results are based on surveys conducted in November and December 2022 of more than 800 IT decision makers in North America, Asia/Pacific, and Europe.Cloud spending is increasing, and an IDC Quick poll of 69 CIOs from its global CIO Executive Council conducted in December found two-thirds of them are already spending more on cloud services than they budgeted. The two studies are cited in the IDC report “Early 2023 Cloud Budget Outlook: Aligning IT Spending with the Business Conditions” published this month.To read this article in full, please click here

Working with image files on the Linux command line

While the best way to view or manipulate image files on Linux is to open them on your desktop for viewing or manipulating with tools like Gimp, there are quite a few ways to get important details on the command line.Identifying image type by file extension In general, image files can be identified on the command line by listing their names. Clearly ".jpg" represents a jpeg file, ".png" a portable network graphics file, ".gif" a graphics interchange format file, ".tiff" a tagged image file and so on.$ ls -l images -rw-rw-r--. 1 shs shs 256093 Jul 15 2018 mycats.jpg -rw-r-----. 1 shs shs 784238 Jul 15 2018 mycats.png -rw-rw-r--. 1 shs shs 6760 Jul 15 2018 arrow.jpg -rw-r-----. 1 shs shs 8853 Jul 15 2018 arrow.png Nearly all of the time you can rely on file extensions accurately reporting the file type, but there's more you can do with additional commands.To read this article in full, please click here

A new role for network pros: application-flow architect

There are a lot of issues that network-management people worry about. We all have heard about faults, failures, breaches. But want to know what long-term problem is keeping the smart members of the network leadership of enterprises up at night? It’s an empty chair. Their chair, at the table that makes the plans that set network requirements and directions today and for years to come. These leaders used to sit in that chair, but now they say there’s no place for them.Application designs determine network requirements We used to build networks from primitive pieces, like digital trunks and routers. Then we built them from services, like IP VPNs. That transformation was jarring to many who’d cut their teeth on real private-network technology, but they were still a big part of the game. Today, we’re still building networks from services, but the services of today are application services that include implicit network features. The really new network is built from connectivity services that are included in cloud and even data-center hosting packages. Application planners design these services, and the decisions they make frame the building-blocks of the network. One chief network officer said he’d gone from building technology to stocking Continue reading

IT to shoulder more responsibility for data center sustainability

Cutting-edge server chips are turning heads for their potential to boost performance, but next-generation processors also run hotter than older designs, and data-center operators will struggle to figure out what to do with limited guidance from chip makers.At the same time, there’s going to be increased scrutiny on the role that IT equipment can play in energy efficiency efforts. These interrelated trends are among the top predictions Uptime Institute is making for data centers this year.“Operators will struggle with new, hotter server chips,” said Jacqueline Davis, research analyst at Uptime, during a web conference on the institute’s 2023 data-center predictions. Meanwhile, “energy-efficiency focus is going to expand to include the IT equipment itself, something that we think is overdue.”To read this article in full, please click here

T-Mobile, Xfinity are tops in latest Ookla speed test report

Network intelligence provider Ookla’s latest research shows that T-Mobile had the fastest mobile network in the US, and that Xfinity edged out several competitors for the top spot among fixed providers in the fourth quarter of 2022, the company announced this week.The median download speed for T-Mobile customers, Ookla said, reached over 151Mbps, marking a sharp increase from the company’s 116Mbps mark in the previous quarter, which was already good enough to make T-Mobile the fastest mobile carrier by a distance.Verizon and AT&T posted gains — rising from around 58Mbps in the third quarter to 69Mbps and 65Mbps, respectively — but both were far behind T-Mobile. Looking at 5G performance specifically, T-Mobile again led the way by a considerable margin, posting an average 216Mbps download speed, compared to 128Mbps from Verizon and 85Mbps from AT&T.To read this article in full, please click here

Roundup of server vendors using new Xeon processors

It’s only two years late, but the fourth generation of Xeon Scalable processors, aka Sapphire Rapids, is hitting the ground running, with every major OEM offering new servers featuring the chips.The 4th Gen Xeon Scalable is notable because it contains a number of specialty computing engines in addition to its x86 cores, and it also has lots of cores as well; up to 60. One of the special engines is for AI acceleration, as Intel is determined to make the CPU viable as an AI processor instead of GPUs. So not surprisingly, many of the new servers are built with AI processing in mind.To read this article in full, please click here

Commands and setting for managing user accounts on Linux

If you’re administering a Linux server, chances are you have a lot of user accounts to manage and, along with these, a lot of files and settings to control. Here are some commands and issues that are important in setting up and managing user accounts and access rights.Dealing with IDs First, in managing user accounts, you need to be aware of both user IDs (UID) and group IDs (GID). Most accounts are set up with each user being the sole member of a group that has the same name as the user’s account. In fact, both are set up when an account is created using the useradd command. When you list a user’s home directory, you should see something like this:To read this article in full, please click here

Top 10 outages of 2022

The most significant network and service outages of 2022 had far-reaching consequences. Flights were grounded, virtual meetings cut off, and communications hindered.The culprits that took down major infrastructure and services providers were varied, too, according to analysis from ThousandEyes, a Cisco-owned network intelligence company that tracks internet and cloud traffic. Maintenance-related errors were cited more than once: Canadian carrier Rogers Communications experienced a massive nationwide outage that was traced to a maintenance update, and a maintenance script error caused problems for software maker Atlassian.BGP misconfiguration also showed up in the top outage reports. Border gateway protocol tells Internet traffic what route to take, but if the routing information is incorrect, then traffic can be diverted to an improper route, which happened to Twitter.
