Marvell, Dell team on SmartNIC for 5G servers

HPE and Qualcomm did likewise last week, because vanilla x86 isn’t going to cut it on the edge


Dell and Marvell have linked arms to create an accelerator card for servers used in 5G networks.

Announced today ahead of the Mobile World Congress (MWC) conference, the "Dell Open RAN Accelerator Card" uses Marvell's Octeon – silicon dedicated to networking chores – so that the CPUs housed in PowerEdge servers used in 5G networks are freed from processing Layer 1 traffic, and can instead focus on running the Open RAN.

Freeing up the CPU for critical workloads and leaving an accelerator to handle plumbing is the same reasoning the likes of Intel, Nvidia, VMware, Pensando, and most hyperscale clouds offer for their decision to add accelerators to servers under the name SmartNIC, Infrastructure Processing Unit or Data Processing Unit. Qualcomm and HPE launched a very similar accelerator last week.

In one regard, this is the way 5G was supposed to happen – the standard encourages disaggregation rather than reliance on single vendors and closed standards.

On the other hand, developing accelerators is recognition that the vision of x86-powered servers satisfying every niche is not entirely realistic – as with both Dell and HPE deciding their boxen need help, it is clear that vanilla servers aren't always up to the job.

Dell is at least trying to make those servers easier to wield, as accompanying its Mobile World Congress announcement of the Accelerator is news of the "Dell Bare Metal Orchestrator management software", code that allows wide and rapid deployment of desired server images (provided they're running 5G stacks from VMware, Red Hat or Wind River) to hundreds or thousands of machines. Which is just what's needed once servers are found bolted on to 5G radio sites across a network.

The accompanying "Bare Metal Orchestrator Modules" allow management of servers across their lifecycle.

Dell has teased this stuff since its October 2021 re-definition of hyperconverged infrastructure as a single-node affair, rather than relying on local clusters.

Reference implementations have of course been cooked up to make this all work as you'd expect because it's a competent vendor that has noticed the opportunity 5G represents. Sam Saba, Dell's head of telecom for Asia Pacific & Japan, told The Register the company has also hired the expertise it needs to satisfy carrier customers.

Saba said when he joined Dell a year ago, it had around 100 staff in the telco team. That number's now closer to 1,000 and Saba said it should end the year with double that number on the books. The company already has a reference customer for a Dell-powered disaggregated 5G – Singaporean carrier Singtel.

As it happens, Singtel said on Tuesday it will offer its 5G-network-as-a-service, with packaged solutions for different industries, and the ability to consume Singtel-provided edge compute resource.

That last capability smells a bit like Dell's Validated Design for Services Edge, which was upgraded ahead of MWC. The house that Mike built has also announced "ProDeploy for NFVI" to offer templates that enable faster network function virtualization rollout and management. ®

  • Meta loves AWS so much, it's, er, using Azure for AI work
    Someone got Zuck'd over

    Meta’s AI business unit set up shop in Microsoft Azure this week and announced a strategic partnership it says will advance PyTorch development on the public cloud.

    The deal [PDF] will see Mark Zuckerberg’s umbrella company deploy machine-learning workloads on thousands of Nvidia GPUs running in Azure. While a win for Microsoft, the partnership calls in to question just how strong Meta’s commitment to Amazon Web Services (AWS) really is.

    Back in those long-gone days of December, Meta named AWS as its “key long-term strategic cloud provider." As part of that, Meta promised that if it bought any companies that used AWS, it would continue to support their use of Amazon's cloud, rather than force them off into its own private datacenters. The pact also included a vow to expand Meta’s consumption of Amazon’s cloud-based compute, storage, database, and security services.

  • Atos pushes out HPC cloud services based on Nimbix tech
    Moore's Law got you down? Throw everything at the problem! Quantum, AI, cloud...

    IT services biz Atos has introduced a suite of cloud-based high-performance computing (HPC) services, based around technology gained from its purchase of cloud provider Nimbix last year.

    The Nimbix Supercomputing Suite is described by Atos as a set of flexible and secure HPC solutions available as a service. It includes access to HPC, AI, and quantum computing resources, according to the services company.

    In addition to the existing Nimbix HPC products, the updated portfolio includes a new federated supercomputing-as-a-service platform and a dedicated bare-metal service based on Atos BullSequana supercomputer hardware.

  • In record year for vulnerabilities, Microsoft actually had fewer
    Occasional gaping hole and overprivileged users still blight the Beast of Redmond

    Despite a record number of publicly disclosed security flaws in 2021, Microsoft managed to improve its stats, according to research from BeyondTrust.

    Figures from the National Vulnerability Database (NVD) of the US National Institute of Standards and Technology (NIST) show last year broke all records for security vulnerabilities. By December, according to pentester Redscan, 18,439 were recorded. That's an average of more than 50 flaws a day.

    However just 1,212 vulnerabilities were reported in Microsoft products last year, said BeyondTrust, a 5 percent drop on the previous year. In addition, critical vulnerabilities in the software (those with a CVSS score of 9 or more) plunged 47 percent, with the drop in Windows Server specifically down 50 percent. There was bad news for Internet Explorer and Edge vulnerabilities, though: they were up 280 percent on the prior year, with 349 flaws spotted in 2021.

  • ServiceNow takes aim at procurement pain points
    Purchasing teams are a bit like help desks – always being asked to answer dumb or inappropriate questions

    ServiceNow's efforts to expand into more industries will soon include a Procurement Service Management product.

    This is not a dedicated application – ServiceNow has occasionally flirted with templates for its platform that come very close to being apps. Instead it stays close to the company's core of providing workflows that put the right jobs in the right hands, and make sure they get done. In this case, it will do so by tickling ERP and dedicated procurement applications, using tech ServiceNow acquired along with a company called Gekkobrain in 2021.

    The company believes it can play to its strengths with procurements via a single, centralized buying team.

  • HPE, Cerebras build AI supercomputer for scientific research
    Wafer madness hits the LRZ in HPE Superdome supercomputer wrapper

    HPE and Cerebras Systems have built a new AI supercomputer in Munich, Germany, pairing a HPE Superdome Flex with the AI accelerator technology from Cerebras for use by the scientific and engineering community.

    The new system, created for the Leibniz Supercomputing Center (LRZ) in Munich, is being deployed to meet the current and expected future compute needs of researchers, including larger deep learning neural network models and the emergence of multi-modal problems that involve multiple data types such as images and speech, according to Laura Schulz, LRZ's head of Strategic Developments and Partnerships.

    "We're seeing an increase in large data volumes coming at us that need more and more processing, and models that are taking months to train, we want to be able to speed that up," Schulz said.

  • We have bigger targets than beating Oracle, say open source DB pioneers
    Advocates for MySQL and PostgreSQL see broader future for movement they helped create

    MySQL pioneer Peter Zaitsev, an early employee of MySQL AB under the original open source database author Michael "Monty" Widenius, once found it easy to identify the enemy.

    "In the early days of MySQL AB, we were there to get Oracle's ass. Our CEO Mårten Mickos was always telling us how we were going to get out there and replace all those Oracle database installations," Zaitsev told The Register.

    Speaking at Percona Live, the open source database event hosted by the services company Zaitsev founded in 2006 and runs as chief exec, he said that situation had changed since Oracle ended up owning MySQL in 2010. This was as a consequence of its acquisition that year of Sun Microsystems, which had bought MySQL AB just two years earlier.

  • Beijing needs the ability to 'destroy' Starlink, say Chinese researchers
    Paper authors warn Elon Musk's 2,400 machines could be used offensively

    An egghead at the Beijing Institute of Tracking and Telecommunications, writing in a peer-reviewed domestic journal, has advocated for Chinese military capability to take out Starlink satellites on the grounds of national security.

    According to the South China Morning Post, lead author Ren Yuanzhen and colleagues advocated in Modern Defence Technology not only for China to develop anti-satellite capabilities, but also to have a surveillance system that could monitor and track all satellites in Starlink's constellation.

    "A combination of soft and hard kill methods should be adopted to make some Starlink satellites lose their functions and destroy the constellation's operating system," the Chinese boffins reportedly said, estimating that data transmission speeds of stealth fighter jets and US military drones could increase by a factor of 100 through a Musk machine connection.

  • How to explain what an API is – and why they matter
    Some of us have used them for decades, some are seeing them for the first time on marketing slides

    Systems Approach Explaining what an API is can be surprisingly difficult.

    It's striking to remember that they have been around for about as long as we've had programming languages, and that while the "API economy" might be a relatively recent term, APIs have been enabling innovation for decades. But how to best describe them to someone for whom application programming interfaces mean little or nothing?

    I like this short video from Martin Casado, embedded below, which starts with the analogy of building cars. In the very early days, car manufacturers were vertically integrated businesses, essentially starting from iron ore and coal to make steel all the way through to producing the parts and then the assembled vehicle. As the business matured and grew in size, car manufacturers were able to buy components built by others, and entire companies could be created around supplying just a single component, such as a spring.
