Microsoft details its ChatGPT hardware investments

Microsoft investment in ChatGPT doesn’t just involve money sunk into its maker, OpenAI, but a massive hardware investment in data centers as well which shows that for now, AI solutions are just for the very top tier companies.The partnership between Microsoft and OpenAI dates back to 2019, when Microsoft invested $1 billion in the AI developer. It upped the ante in January with the investment of an additional $10 billion.But ChatGPT has to run on something, and that is Azure hardware in Microsoft data centers. How much has not been disclosed, but according to a report by Bloomberg, Microsoft had already spent “several hundred million dollars” in hardware used to train ChatGPT.To read this article in full, please click here

Dell offers bare metal cloud via colocation

A new deal between Dell and colocation services provider Cyxtera will enable enterprises to access Dell’s PowerEdge infrastructure for bare-metal deployments in Cyxtera facilities.“Bare metal” cloud services means you get the hardware with no software loaded. Typically, a cloud services provider offers an operating system, usually Linux, and accompanying infrastructure. With bare metal, you just get CPU cores, memory, networking and storage but no OS. You provide your own environment.Under the deal, enterprises will be able to deploy Dell hardware through Cyxtera’s enterprise bare-metal service, an on-demand offering that connects an enterprise’s existing on-premises infrastructure with the colocation environment.To read this article in full, please click here

Using the at command to schedule tasks on Linux

To schedule a command or script to run at some particular time, the at command is perfect and provides many options for specifying the time you want it to run. It will set the task up to be run whenever you specify, and you can view the scheduled tasks or even change your mind and cancel one of them as you see fit.The at command differs from cron in that it sets up a command or script to run only once, while cron allows you to set up commands or scripts to be run on a specified schedule – whether every day, once a week, a couple times a month or even just once a command syntax Using the at command is relatively easy, though it has a lot of options, particularly on how you specify the time a task should be run. If you specify a time like shown below, the task will be set up to be run the next time you reach 15:27 (3:27 PM), whether that's today or tomorrow.To read this article in full, please click here

How network pros can fight being squeezed out of cloud decisions

There's a rumbling in the cloud as network professionals increasingly seek to reclaim what they believe is their rightful place in the enterprise management hierarchy.Network knowledge is now widespread within many other IT disciplines. "This means it's now sometimes easy for other teams to assume that they know all they need to know about networking, so they don't need to bother the network team," observes Josh Stephens, CTO of multi-cloud network automation provider BackBox.Network pros have unique perspectives. When it comes to multicloud decision-making, IT, cloud, cybersecurity, and network professionals all bring different perspectives and talents to the table. "IT teams have a deep understanding of the organization's overall technology, while cloud teams have expertise in cloud-based technology solutions, and cybersecurity teams have a thorough understanding of [cloud] security risks," says Dan Dulac, vice president of solutions strategy at network infrastructure provider Extreme Networks. Combining the insights of these experts, along with network professionals, is the best way for organizations to make informed decisions about their multicloud strategy, he says.To read this article in full, please click here

HPE Aruba, Microsoft Azure, and reelyActive speed streaming of IoT data to the cloud

Aruba Networks, Microsoft Azure and open-source vendor reelyActive have teamed-up to make it easier to bring IoT device data to cloud applications.The package, Aruba IoT Transport for Azure, brings together three separate components to make it work: Aruba Access points that incorporate both Wi-Fi and IoT radios to serve mobile connectivity, connect to IoT devices, and function as embedded IT-to-IoT gateways simultaneously and securely. HPE Aruba Networking IoT Transport for Azure service that encodes IoT-device data streamed through the access points into a format compatible with Microsoft Azure IoT Hub, which centrally ingests, provisions, and manages device data. reelyActive Pareto Anywhere for Microsoft Azure a new free open-source converter that reformats IoT data and units of measurement such as temperature and power into a universal format compatible with Microsoft analytics, Power BI and other Azure applications. The tool abstracts the original data format so that the data seen by applications are intelligible, consistent streams of immediately consumable data in recognizable units of measurement. Azure applications can directly consume data from a heterogeneous mix of BLE, 800MHz and 900MHz EnOcean specialized IoT devices that plug into the USB port on HPE Aruba Networking access points without a dedicated on-premises gateway.

Roundup of high-speed networking updates from Intel, Marvell, Ranovus

The need for speed in the data center has never been greater, as data sets for AI and machine learning grow exponentially. Enterprises also need bandwidth to move increasingly large data sets, and security to protect data in transit. To that end, three vendors have announced new capabilities in the high-speed networking game. So, let’s run them down.Intel launches Agilex 7 FPGAs with F-Tile Intel has introduced its latest FPGA-based networking processor, the Agilex 7 with F-Tile. This PAM4 and NRZ dual-mode serial interface tile can deliver up to 116 Gbps and hardened 400 GbE intellectual property. This is double the bandwidth per channel of the previous generation of Intel FPGAs with reduced power consumption.To read this article in full, please click here

Vast Data focuses on metadata cataloging, encryption support and snapshots

Flash storage vendor Vast Data has released what it claims is its biggest software release, updating and adding new features around data catalogs that will allow enterprises to tag data with user-defined information and to query datasets that meld structured, unstructured and semi-structured data.Vast has actually announced two revisions to its software, 4.6 and 4.7. The software itself has no formal name, just a version number. Version 4.6, available now, is a major release, and 4.7, available this spring, will be a minor release, according to Steve Pruchniewski, director of product marketing at VAST. “Major feature releases are core to the product's evolution, where minor feature releases typically contain bug fixes and holdovers from previous feature releases,” Pruchniewski said.To read this article in full, please click here

Best-of-breed networking: There’s an opportunity for white boxes in the WAN

Everyone wants the best network, so they say, but as usual with “bestness” goals, there’s not much agreement on how to achieve it. Do you go for best-of-breed in your equipment, or maybe for three vendors per product area, or maybe open white-box networks? A bit over three-quarters of enterprises said in 2020 that open networks and white boxes would give them best of breed options, but what’s happened since then seems like a blast from the past, vendor-wise.Let’s start with an interesting truth. Well over 95% of established enterprises who can look back to the origins of their networks say that they started off with a single-vendor network. Enterprises who launched within the last five years (which are very few) account for almost all those who didn’t start off with one vendor. If you think about it, this is logical, because starting off with networking is daunting enough without adding in the complication of network integration and the management of multiple sources of technology.To read this article in full, please click here

When does SD-WAN make sense?

This is an important question, with a simple answer: it depends. And the main thing it depends on is, why an organization wants an SD-WAN in the first place. Answering that goes a long way to answering the size question.The baseline assumption is that the IT department sees a need for the organization to have a iprivate WAN, rather than every site communicating solely over the public internet.This is not a trivial assumption any more. As little as a decade ago, it was standard to have a private WAN for even two or three locations, since they would most likely be sharing back-end services of some sort from a common data center. Today, no such assumption can be made. Many companies grow to have many sites without needing private connectivity among them because everything they do is hosted in one or another external cloud. And, as some organizations migrate services out of data centers, they find that they need private WAN links at fewer sites or only at their data centers.To read this article in full, please click here

Intel delays next GPU Max until 2025

A significant change to Intel's high performance computing roadmap gives competitors AMD and Nvidia plenty of time to grab market share.Intel has a pair of processors called CPU Max and GPU Max. Both feature high bandwidth memory (HBM) on the die which greatly increases performance. The successor to the GPU Max, known as Rialto Bridge, was due later this year or early next year.Instead, Intel cancelled Rialto Bridge, and its successor – Falcon Shores – isn't coming until 2025. Longer term, Intel plans to have one processor, called an XPU, that will combine CPU and GPU cores on one die, but that will come after Falcon Shores.To read this article in full, please click here

What is power over Ethernet (PoE)?

Power over Ethernet (or PoE) is the delivery of electrical power to networked devices over the same Ethernet cabling that connects them to the LAN. This simplifies the devices themselves by eliminating the need for an electric plug and power converter, and makes it unnecessary to have separate AC electric wiring and sockets installed near each device.Many enterprises have come to rely on PoE to bring electricity over existing data cables to Wi-Fi access points, firewalls, IP phones, and other infrastructure throughout their networks.To read this article in full, please click here

Saving commands to a file using Ctrl-x-e

One very interesting trick that you may not know is that you can type a line of text (presumably a command) on the Linux command line and immediately save it to a file by pressing just three keys. The editor that will open up will depend on your $EDITOR setting that you can view using the command shown below:$ echo $EDITOR nano If you prefer to use a different editor, use a command like this before typing or moving back to the command that you want to save:$ export EDITOR=vi And don't forget to save this change to your .bashrc (or other start-up file) if you want to make this change permanent. For example:To read this article in full, please click here
