BrandPost: Unlocking Higher Education: AI Improves Student Experience, Institutional Excellence

Over the past two years, institutions of higher education (IHEs) have undergone a tremendous amount of change. The future is more uncertain than ever. To prepare for the future, today’s institutional leaders must navigate the complexities of hybrid-first learning and operations to create flexible, high-quality digital experiences.Artificial intelligence (AI) has emerged as a leading focus of IT investment for higher education leaders with the aim of enhancing the student experience, improving the financial health of their organization, and driving institutional excellence. But without a network capable of meeting these expectations and IT staff equipped to manage this complex IT landscape, institutions risk delivering a poor end-user experience.To read this article in full, please click here

Dell expands data-protection product line

Dell Technologies has announced new products and services for data protection as part of its security portfolio.Active data protection is often treated as something of an afterthought, especially compared to disaster recovery. Yet it's certainly a problem for companies. According to Dell’s recent Global Data Protection Index (GDPI) research, organizations are experiencing higher levels of disasters than in previous years, many of them man-made. In the past year, cyberattacks accounted for 48% of all disasters, up from 37% in 2021, and are the leading cause of data disruption.One of the major stumbling blocks in deploying data-protection capabilities is the complexity of the rollout. Specialized expertise is often required, and products from multiple vendors are often involved. Even the hyperscalers are challenged to provide multicloud data-protection services.To read this article in full, please click here

Ways to look at logged in users on Linux

There are quite a few ways on Linux to get a list of the users logged into the system and see what they are doing. The commands described in this article all provide very useful information.users The users command displays a simple list of logged-in users. In this example, one user is logged in twice and is, therefore, listed twice.$ users nemo popeye shs shs Note that the users are listed in alphabetical order.who The who command provides additional information. The login terminal is identified along with the login date and time. The final field displays the terminal or the IP address of the connecting system.To read this article in full, please click here

World’s fastest supercomputer is still Frontier, 2.5X faster than #2

Frontier, which became the first exascale supercomputer in June and ranked number one among the fastest in the world, retained that title in the new TOP500 semiannual list of the world’s fastest.Without any increase in its speed—1.102EFLOP/s—Frontier still managed to score 2.5 times faster that the number two finisher, Fugaku, which also came in second in the June rankings. An exascale computer is one that can perform 1018 (one quintillion) floating point operations per second (1 exaFLOP/s).Despite doubling its maximum speed since it was ranked number three in June, the Lumi supercomputer remained in third-place.There was just one new member of the top-ten list, and that was Leonardo, which came in fourth after finishing a distant 150th in the TOP500 rankings in June.To read this article in full, please click here

Looking at user login time with the ac command

While not a very well known Linux command, ac can provide very useful stats on user login time. In its simplest form, it will show you how much time users have spent on the system in the time period covered by the wtmp file. All you have to type is “ac” to get a figure showing overall login time for all users.$ ac total 8360.60 The figure above indicates that users spent a total of 8,360.6 hours on the system. Looking at the wtmp file with the who command, we can see that the saved logins started on June 6th – a little more than 6 months earlier.$ who /var/log/wtmp | head -2 shs tty2 2022-06-06 16:00 (tty2) shs pts/1 2022-06-06 16:23 (192.168.0.12) To look at the times by user, add the -p (people) argument.To read this article in full, please click here

Should security systems be the network?

Recently during a research interview with a small but fast-growing business, for the first time I encountered an organization with a “no-network-vendor” network. That is, instead of using Cisco or Dell or even a white-box solution for switching and routing, the company deployed only Fortinet equipment for its entire network. That is, every network component is part of the security infrastructure for them.They built the network this way not just to bake security into its core (a great idea in itself) but also for: ease of management: they have one tool, it manages every component ease of deployment: they have only two or three versions of each appliance, all the same except for capacity and port count ease of expansion to new locations: every site is the same as any other site of similar size They have a small stock of replacement appliances on the shelf, with which they provide rapid recovery for all locations. They could easily also consume security-operations center as-a-service, and use professional services for nearly all the rest of their network operations. In essence, their security solution could become their complete network solution as well.To read this article in full, please click here

Intel is shipping the next generation of Xeon Scalable processors

After almost a year and a half of delays, Intel has begun to ship its 4th Generation Xeon Scalable processors, code-named Sapphire Rapids, to customers, and it has set January 10, 2023 as the formal launch date.The launch is a formality because, according to an Intel spokesperson, the new Xeons are already shipping to customers—OEMs—now, but it falls to those OEMs to announce their product release plans.CEO Pat Gelsinger said during the company’s earnings call last week that the company was ramping up production for launch and that he expected the new Xeons to see the fastest ramp to one million units ever.The challenge for Intel wasn’t in design, it was manufacturing. This will be the first generation of chips using Intel 7 fabrication, an advanced 10nm design that took years to get right.To read this article in full, please click here

3 ways to reach the cloud and keep loss and latency low

Adoption of public cloud IaaS platforms like AWS and Azure, and PaaS and SaaS solutions too, has been driven in part by the simplicity of consuming the services: connect securely over the public internet and start spinning up resources. But when it comes to communicating privately with those resources, there are challenges to address and choices to be made.The simplest option is to use the internet—preferably an internet VPN—to connect to the enterprise’s virtual private clouds (VPC) or their equivalent from company data centers, branches, or other clouds.However, using the internet can create problems for modern applications that depend on lots of network communications among different services and microservices. Or rather, the people using those applications can run into problems with performance, thanks to latency and packet loss.To read this article in full, please click here

Kyndryl’s first year yields revenue challenges and a plan to make more

In the year since it spun out of IBM, Kyndryl has made a number of big strides in establishing itself as a core infrastructure service management player, but challenges remain.For example, while it has substantially expanded its partnerships and technology, its financial situation hasn’t shown a similar bump. Just this week the company reported  second quarter revenues of $4.2 billion, a year-over-year drop of 9%. The company has reported similar results in other recent quarters. “Currency and energy-costs impacts are superseding the operational progress we’re making,” Kyndryl CFO David Wyshner told Wall Street analysts during the firm’s 2Q 2023 call this week. “And while the risk of a global recession has clearly increased, we continue to see broadbase demand for digital transformation in infrastructure services.”To read this article in full, please click here

BrandPost: The New Gold Standard: How AIOps Is Transforming Network Capability

You know it better than anyone: the network has become essential infrastructure for any successful enterprise. COVID-19, migration to multicloud, and new application requirements have only amplified pressure on enterprise IT to deliver high-availability, secure network services anywhere, anytime, and on any device.This isn’t a passing fad. Several key trends will drive network growth and complexity for years to come, including: The growing popularity of hybrid and fully remote work models Resource gaps exasperated by the great resignation Dramatic growth in video and cloud meetings An increase in data security regulations To address these challenges and best position themselves for the future, enterprises must implement more intelligence in the network. Modern AIOps uses artificial intelligence and machine learning to assist IT in managing, troubleshooting, and fixing network problems. As a result, AIOps is becoming a key success factor in managing modern enterprise networks.To read this article in full, please click here

AMD posts operating loss, but solid growth for data center, embedded segments

AMD announced third quarter results this week, and while it posted a $64 million loss in terms of overall operating income—mainly due to its acquisition of Xilinx—but large gains in the company’s data center, embedded and gaming segments provided an encouraging note.Total revenue rose by 29% for the third quarter of 2022, to $5.56 billion from $4.31 billion one year ago. Gross profit also rose in year on year terms, from $2.08 billion in last year’s third quarter to $2.35 billion for the past three months. The decline in operating income was caused by much higher operating expenses, which more than doubled in the third quarter, rising from $1.14 billion a year ago to $2.42 billion in the most recent figures.To read this article in full, please click here
