Microsoft uses AI to boost its reuse, recycling of server parts

Microsoft is bringing artificial intelligence to the task of sorting through millions of servers to determine what can be recycled and where.The new initiative calls for the building of so-called Circular Centers at Microsoft data centers around the world, where AI algorithms will be used to sort through parts from decommissioned servers or other hardware and figure out which parts can be reused on the campus. READ MORE: How to decommission a data center Microsoft says it has more than three million servers and related hardware in its data centers, and that a server's average lifespan is about five years. Plus, Microsoft is expanding globally, so its server numbers should increase.To read this article in full, please click here

Federated learning improves how AI data is managed, thwarts data leakage

Privacy is one of the big holdups to a world of ubiquitous, seamless data-sharing for artificial intelligence-driven learning. In an ideal world, massive quantities of data, such as medical imaging scans, could be shared openly across the globe so that machine learning algorithms can gain experience from a broad range of data sets. The more data shared, the better the outcomes.That generally doesn't happen now, including in the medical world, where privacy is paramount. For the most part, medical image scans, such as brain MRIs, stay at the institution level for analysis. The result is then shared, but not the original patient scan data.

Many data-center workloads staying on premises, Uptime Institute finds

Another study finds that the data center is far from dying. That's not surprising to learn from the Uptime Institute's annual data center survey. However one trend that did stand out in the research is that power efficiency has "flatlined" in recent years.Uptime says big improvements in energy efficiency were achieved between 2007 and 2013 using mostly inexpensive or easy methods, such as simple air containment. But moving beyond those gains involves more difficult or expensive changes. Since 2013, improvements in power usage effectiveness (PUE) have been marginal, according to the group.To read this article in full, please click here

Organic data-transfer technology holds promise for IoT

Visible light communications (VLC) systems are an alternative to radio-based wireless networks and serve a dual purpose: They provide in-building lighting, and they use light waves for data transmission. VLC uses modulated light as a data carrier, while the visible spectrum provides light.Using VLC for data transmission has some advantages. It offers decent bandwidth; it offers security because walls, floors and roofs obstruct the data-carrying wavelengths, which reduces the risk of eavesdropping; and it's inexpensive since it's simply incorporated into light fixtures or, in emerging developments, worked into displays and other surfaces.To read this article in full, please click here

Ampere announces 128-core Arm server processor

Ampere – the semiconductor startup founded by former Intel executive Renee James and not to be confused with the new line of Nvidia cards – just introduced a 128-core, Arm-based server processor to complement its 80-core part.The new processor, Altra Max, comes just three months after the company launched its first product, the 80-core Altra. Ampere says the new processor will be fully socket compatible with the existing part so customers can just do a chip swap if they want. Ampere "This is not replacing Altra," says Jeff Wittich, senior vice president of products at Ampere and one of many ex-Intel executives at Ampere. "I expect there will be workloads and customers who will use Altra and Altra Max together for a long time. Anything suited for Max will be suited for Altra for a long time."To read this article in full, please click here

Ambient ‘T-rays’ could help power IoT devices

Most things with a measurable temperature – human beings going about their daily routines, inert objects – generate terahertz waves, radiation that is sandwiched between infrared and microwave on the electromagnetic spectrum.So far, these waves haven’t proved very useful, but now scientists at MIT are trying to harness them with devices that use them to generate electricity that could charge the batteries of cellphones, laptops, even medical implants.[Get regularly scheduled insights by signing up for Network World newsletters.] If successful, the charging devices would passively gather the waves and generate DC current at room temperature, something that hasn’t been accomplished before. Previous devices that can turn terahertz waves – T-rays – to electricity only work in ultracold environments, according to an MIT News article about the project.To read this article in full, please click here

How to backup essential data but not the garbage

Something as simple as how you tell your backup product which files and databases to backup can have a massive impact on your recoverability. Proper backup selection is essentially a balance between ensuring that everything that should be backed up is indeed backed up, while also trying not to backup worthless data.Physical server inclusion Virtually all backup products require some initial installation and configuration at the level of a physical server. This means that for any of the tactics mentioned in this article to work, one must first install the appropriate software and authorization on each physical server in the data center. This means every VMware or Hyper-V server (not to be confused with each VM on those servers), every physical UNIX or Windows server, and any cloud services that are being backed up. Someone must make that initial connection and authentication before the backup system can perform its magic.To read this article in full, please click here
