IoT could help at-risk seniors

The internet of things is also, in part, the internet of people, particularly in the plans of an Ontario-based chain of retirement homes and long-term care facilities called Schlegel Villages.The company, which is based in Kitchener, Ontario, designs its facilities to be less institutional-looking and more friendly, preferring to call them “villages.” But it’s got a problem to deal with, as at-risk seniors can sometimes become confused and attempt to leave.[ For more on IoT see tips for securing IoT on your network, our list of the most powerful internet of things companies and learn about the industrial internet of things. | Get regularly scheduled insights by signing up for Network World newsletters. ] According to Schlegel’s IT director, Chris Carde, it’s a serious issue.To read this article in full, please click here

How we chose 10 hot storage startups to watch

The hardest thing about compiling a startup roundup isn’t choosing 10 hot startups. Rather, it’s eliminating the many promising startups that could easily end up being more successful than any one of my top picks.It’s a challenge that comes with the territory. After all, the success or failure of any given startup will be due to many factors, plenty of which are impossible to measure.

10 hot storage companies to watch

Innovations such as software-Defined Storage (SDS), hyper-converged infrastructures (HCI), and blockchain have investors flocking to enterprise storage startups, and this market shows no signs of slowing down.Collectively, the 10 startups featured in this roundup have raised more than $736 million in VC funding. This total is even more impressive when you factor in two startups not included in that calculation. One of them is entirely self-funded, while the other has a unique business model and an equally unique source of non-VC funding: an ICO, or Initial Coin Offering.[ Don’t miss customer reviews of top remote access tools and see the most powerful internet of things companies . | Get weekly insights by signing up for our CIO Leader newsletter. ] According to research firm IDC, the worldwide enterprise storage market expanded by 13.7 percent year-over-year to just under $13.6 billion in the fourth quarter of 2017. Other research firms believe the growth rate will accelerate in the near term. Research and Markets, for instance, predicts that one fast-growing segment of the overall enterprise storage market, cloud storage, will expand to become a $92.5 billion market by 2022.To read this article in full, please click here

Could We Build an IXP on Top of VXLAN Infrastructure?

Andy sent me this question:

I'm currently playing around with BGP & VXLANs and wondering: is there anything preventing from building a virtual IXP with VXLAN? This would be then a large layer 2 network - but why have nobody build this to now, or why do internet exchanges do not provide this?

There was at least one IXP that was running on top of VXLAN. I wanted to do a podcast about it with people who helped them build it in early 2015 but one of them got a gag order.

JUNIPER QFX10K | EVPN-VXLAN | EVPN ANYCAST GATEWAY VERIFICATION

This article is the second post in a series that is all about EVPN-VXLAN and Juniper QFX technology. This particular post is focussed specifically on EVPN Anycast Gateway and how to verify control plane and data plane on Juniper QFX10k series switches.

Overview

In my first post, I explained how to verify MAC learning behaviour in a single-homed host scenario. This time we’re going to look at how to verify control plane and data plane when using EVPN Anycast Gateway. As explained in my previous post, verifying and troubleshooting EVPN-VXLAN can be very difficult. Especially when you consider all the various elements that build up the control plane and data plane.

So, what is EVPN Anycast Gateway?

During the initial conception of EVPN L3 gateway, it was assumed that all PE devices would be configured with a Layer 3 interface (IRB) for a given Virtual Network. It was also intended that all IRB interfaces would be configured with the same IP address thus creating a redundant gateway mechanism.

This worked great until EVPN-VXLAN came along and crucially the hardware that was being deployed at the leaf layer no longer provided support for VXLAN L3 Gateway (IRB). As a result, Anycast Gateway, or Virtual Gateway Continue reading

Nvidia’s DGX-2 System Packs An AI Performance Punch

When Nvidia co-founder and chief executive officer Jensen Huang told the assembled multitudes at the keynote opening to the GPU Technology Conference that the new DGX-2 system, weighing in at 2 petaflops at half precision using the latest Tesla GPU accelerators, would cost $1.5 million when it became available in the third quarter, the audience paused for a few seconds, doing the human-speed math to try to reckon how that stacked up to the DGX-1 servers sporting eight Teslas.

This sounded like a pretty high price, even for such an impressive system – really a GPU cluster with some CPU …

BrandPost: What IT Needs to Learn from New Education Technologies

The combination of new technology, the emergence of the digital generation, and technology that dramatically reduces the impact of distance on learning has fundamentally changed K-12 education. It’s no longer a case of “engaging with technology,” but technology that actually empowers the learning process.To start, device-based learning is the new normal. Unlike decades ago when the use of technology was limited to an hour a day in the “PC Lab,” devices are now used constantly. And unlike the PC days, these new devices depend on central servers, storage, and the network to deliver the apps and information used for coursework. If your central IT—either the systems or the supporting data center—cannot provide very high levels of reliability, teachers and students will lose valuable class time.To read this article in full, please click here

Nvidia Memory Switch Welds Together Massive Virtual GPU

It has happened time and time again in computing in the past three decades in the datacenter: A device scales up its capacity – be it compute, storage, or networking – as high as it can go, and then it has to go parallel and scale out.

The NVLink interconnect that Nvidia created to lash together its “Pascal” and “Volta” GPU accelerators into a kind of giant virtual GPU were the first phase of this scale out for Tesla compute. But with only six NVLink ports on a Volta SXM2 device, there is a limit to how many Teslas can …
