Why aren’t optical disks the top choice for archive storage?

Optical media is the longest lasting medium currently in production. It can reliably hold onto your data for 50-100 years without power or cooling, and without the worry of magnetic degradation. Using recordable optical media such as DVD-R is perfectly suitable for long-term archiving because it is write-once, read-many, meaning it is physically immutable—cannot be changed—so the data on it is tamper-proof.[Get regularly scheduled insights by signing up for Network World newsletters.] It seems, then, that optical media might dominate archived storage, but it doesn’t. To explore why, first let’s take a look at the technology.To read this article in full, please click here

Cisco upgrades network and collaboration tools for hybrid work

The growing impact of hybrid work is resulting in a reassessment of the IT network infrastructure including the ability to glean analytic details from remote workers and ensure collaboration assets are working properly.Going forward, organizations should expect Cisco products that will help to further lock down networks and support application-monitoring and collaboration environments for hybrid workers, Todd Nightingale, the company’s executive vice president and general manager for enterprise networking cloud told Network World head of his keynote at this week’s Cisco WebexOne 2021 virtual conference.To read this article in full, please click here

Gartner: Top strategic predictions for 2022 and beyond

Expect the unexpected – that’s just one of the core premises IT leaders need to embrace in the next few years, according to Gartner's top strategic predictions for 2022 and beyond.IT leaders need to be able to move in multiple strategic directions at once, said Daryl Plummer, distinguished research vice president and Gartner Fellow, to the virtual audience at the firm’s IT Symposium/Xpo Americas, held this week.Network certs: Significant raises for the right ones “Resilience, opportunity and risk have always been components of good business strategy, but today these issues hold new meaning,” Plummer said. “This year’s predictions embody how resilience must be built in more non-traditional ways, from talent to business modularity, while opportunity and risk must be viewed with a greater sense of urgency.”To read this article in full, please click here

Arm creates virtual IoT chips to accelerate development

It can take years for a CPU to go from design to silicon, so Arm is helping developers get a jump on things by putting virtual models of its chip designs in the cloud. The virtual models will allow developers to write and test applications before the actual silicon ships.Dubbed Arm Total Solutions for IoT, the project is a full-stack solution intended for Internet of Things applications and use cases. Arm says the early access for developers, OEMs and service providers, as well as the reduction in product design cycles, could accelerate deployments by up to two years.Arm doesn’t make chips the way Intel and AMD do. It makes designs and licenses them to more than 800 OEMs, which are responsible for everything from embedded devices to servers. Once Arm releases the basic chip design to its partners, the partners then add their own IP to differentiate from the competition, which takes time.To read this article in full, please click here

Intel’s 2nd-gen neuromorphic chip is 10x smarter than the first

Four years after Intel first introduced Loihi, the company’s first neuromorphic chip, the company has released its second generation processor, which Intel says will provide faster processing, greater resource density, and improved power efficiency.CPUs are often called the brains of the computer but aren’t, really, since they process only a handful of tasks at once in a serial manner, nothing like what the brain does automatically to keep you alive. Neuromorphic computing attempts to replicate the functions of the brain by performing numerous tasks simultaneously, with emphasis on perception and decision makingChip shortage will hit hardware buyers for months to years Neuromorphic chips mimic neurological functions through computational “neurons” that communicate with one another. The first generation of Loihi chips had around 128,000 of those digital neurons; the Loihi 2 has more than a million.To read this article in full, please click here

Sweet-spot spectrum for enterprise 5G is growing, but slowly

A new auction for enormously valuable mid-band spectrum and a rollback of availability for a different piece of it illustrates the uneven progress of 5G rollouts in the U.S. and represents a challenge for enterprises looking to take advantage of 5G technology. 5G resources What is 5G?

A dive into Kyndryl, IBM’s managed-services spin-off

Thanks to  a US Securities and Exchange Commission filing new details have emerged about Kyndryl, the IBM spin-off of its managed-infrastructure services unit into a separately traded public company.Kyndryl does exactly what the managed-infrastructure services unit of IBM’s Global Technology Services segment does: manage enterprises IT infrastructure, whether it comes from IBM or another vendor. That’s a challenge for Kyndryl because it has to deal with the trend toward cloud services and against on-premises infrastructure.The split is expected to be complete by the end of 2021, and when it was announced last year, IBM CEO Arvind Krishna said IBM will focus on open hybrid-cloud and AI capabilities while Kyndryl would focus on modernizing customer infrastructure.To read this article in full, please click here

Installing packages on Linux and Mac with Homebrew

Ever heard of Homebrew? It’s a package manager with a very unusual feature. It allows ordinary users to install packages without using sudo, and it’s available for both macOS and Linux. While the tool on each of these systems is referred to as Homebrew, the Linux version installs as linuxbrew.Once installed, users can use Homebrew via the brew command to install packages very easily. Installation of Homebrew itself, however, does generally require sudo privileges and installs in /home/linuxbrew.The man page for the brew command calls it “The Missing Package Manager for macOS (or Linux)”.To read this article in full, please click here

4 questions that get the answers you need from IT vendors

It’s the time of year when most enterprises are involved in a more-or-less-formal technology review cycle, as a preparatory step for next year’s budgeting. They’ve done this for decades, and it’s interesting to me that in any given year, enterprises share roughly three of their top five priorities. It’s more interesting that over three-quarters of enterprises carry over at least two of their top five priorities for multiple years. Why aren’t they getting addressed? They say their top problem is an “information gap.”Buyers adopt network technologies that improve their business, not just their network. They have to justify spending, particularly spending on some new technology that someone inside or outside has suggested. That means that they have to understand how it will improve operations, how they’ll deploy it, and what the cost will be. To do this for a new technology, they need information on how that improvement would happen—and they say they’re not getting it.To read this article in full, please click here

Ananki startup tries to simplify private 5G

A startup using open-source components to offer software-defined private 5G as a service hopes to attract enterprises with an architecture that it says is as simple as Wi-Fi's. 5G resources How 5G frequency affects range and speed Private 5G can solve some problems that Wi-Fi can’t Private 5G keeps Whirlpool driverless vehicles rolling 5G can make for cost-effective private backhaul CBRS can bring private 5G to enterprises Called Ananki, the company requires little of enterprises in order to deploy the service: Customers set up small-cell 5G radios on-site, point them toward a cloud network running the Ananki software, install SIMs on the enterprise hardware that will tap into the service, and Ananki’s automation remotely configures the radios and provisions the SIMs.To read this article in full, please click here

Kioxia seeks to make the SSD more programmable

NAND flash maker Kioxia has expanded its Software-Enabled Flash technology to bring a greater degree of programmability to NAND storage. The move will benefit hyperscalers the most but will have benefits for enterprises and SMBs as well.Kioxia (formerly Toshiba) first introduced SEF last year. It’s an open-source API that operates as a new kind of hardware flash controller to offload some functions to a controller, thus freeing up the CPU, while allowing large data-center environments to manage at scale.Because the API is open source, competitors in the flash space can adopt the API and customize it for their hardware. Hyperscalers think about SSDs in terms of deploying and serving workloads at scale. Kioxia notes that cloud providers often have different types of drives they deploy for different use cases, like block storage versus file storage or ZNS.To read this article in full, please click here
