Aruba switch can cut the need for separate, single-function appliances

Hewlett Packard Enterprise company Aruba is taking the wraps of a new flagship data-center switch aimed at helping to better control and secure hybrid-cloud traffic in the enterprise.The Aruba CX 10000 Series switch is a top-of-rack, L2/3 data-center box with 3.2Tbps of switching capacity, 48 ports of line rate 10/25GbE and six 40/100GbE ports, the company says. But its most intriguing component is an integrated Elba programmable data processing unit (DPU) from Pensando that helps eliminate the need for separate appliances for security and load balancing, for example.The 10 most powerful companies in enterprise networking 2021 Pensando is a startup lead by a crew of ex-Cisco stars including its chairmen of the board, former Cisco CEO John Chambers. Others leaders of the company include former Cisco engineering icons Mario Mazzola, Prem Jain, Luca Cafiero and Soni Jiandani, collectively known as MPLS based on their first initials. The MPLS group has founded a number of companies that were spun back into Cisco during Chamber’s time as CEO including Andiamo Systems for SAN switching, Nuova Systems for data-center switching and Insieme Networks for software-defined networking systems.To read this article in full, please click here

Gartner: 8 security trends facing the enterprise

As organizations become less centralized they face new security challenges that require new ways of addressing threats that will change the basic fabric of network security, according to Gartner analysts.A persistent challenge adapting to these changes is the skills gap--finding IT pros with the technical know-how to meet evolving security issues, Peter Firstbrook, Gartner vice president and anayst told attendees at Gartner IT Symposium/Xpo 2021 Americas.Gartner: IT skills shortage hobbles cloud, edge, automation growth “Cybersecurity teams are being asked to secure countless forms of digital transformation and other new technologies, and if they don’t have those skilled practitioners they move toward managed or cloud-delivered services where they might not have as much control as they’d like,” Firstbrook said.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? Fast wireless technology for enterprises and phones 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 The mid-band is valuable because it’s in a “Goldilocks” zone of the wireless spectrum—its frequencies are high enough to support higher throughput, while also being low enough to propagate effectively across relatively large areas.To read this article in full, please click here

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

Modernizing a data-center network is no easy task under any conditions, but when a healthcare system that includes hospitals and emergency care depends on that network, the pressure is only more intense.That’s the challenge that Tom Hull, CIO of Kaleida Health, the largest healthcare system in western New York, has undertaken in the past year-and-a-half with the goal of building a secure, software-defined data-center environment capable of moving the provider into the future.To read this article in full, please click here

For networking pros, every month is Cybersecurity Awareness Month

When National Cybersecurity Awareness Month (NCSAM) was launched in October 2004, it was a modest affair, offering anodyne advice to individual Americans and US businesses along the lines of making sure to update your antivirus software twice a year.Since then NCSAM has grown into an event-packed month with star-studded guest panels, annual launches in various cities (looking at you, Ypsilanti, Michigan!), the participation of federal cybersecurity officials, and weekly themes. This year, for example, the themes in each successive week are: Be Cyber Smart Phight the Phish! Experience. Share. (Cybersecurity Career Awareness Week) Cybersecurity First Linux security: Cmd provides visibility, control over user activity Not sure why the organizers didn’t make “Cybersecurity First” the theme of the month’s first week, but it is not for me to second-guess the federal Cybersecurity & Infrastructure Security Agency (CISA) and the public/private National Cyber Security Alliance (NCSA), organizers of the annual awareness month.To read this article in full, please click here

The new internet speed record twice as fast as the old one

Everyone wants faster internet speeds. Even people who already have high-speed connections want faster internet, including enterprise workers and IT pros. More speed is what they need, or at least what they would strongly prefer, because the faster data is transmitted between two devices, the faster decisions can be made and actions taken. In the Darwinian digital economy, slow Internet speeds are for laggards and also-rans!So how fast is fast? Some might say the average US internet speed of 99.3 Mbps as measured earlier this year by HighSpeedInternet.com is more than adequate, while an enterprise with a sizable workforce and growing number of connected devices and edge networks would need far more bandwidth.To read this article in full, please click here
