Organic data-transfer technology holds promise for IoT

Published on 4th August, 2020, 11:00 AM

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.

Cisco urges patching flaws in data-center, SD-WAN gear

Published on 30th July, 2020, 9:35 PM

Cisco has issued a number of critical security advisories for its data center manager and SD-WAN offering customers should deal with now.

On the data center side, the most critical – with a threat score of 9.8 out of 10 – involves a vulnerability in the REST API of Cisco Data Center Network Manager (DCNM) could let an unauthenticated, remote attacker bypass authentication and execute arbitrary actions with administrative privileges on an affected device.

Cisco DCNM lets customers see and control network connectivity  through a single web-based management console for the company’s Nexus, Multilayer Director Switch, and Unified Computing System products.

Switch turns to Tesla for renewable energy storage

Published on 28th July, 2020, 7:53 PM

Data center provider Switch has selected Tesla as the battery supplier for a massive solar project at its northern Nevada data center facilities.

It's a geographically easy alliance as Switch's campus is right near Tesla's Gigafactory Nevada manufacturing facility. While best known for its cars, Tesla has also made quite an entry in the battery space with products such as the Powerwall, Powerpack, and Megapack energy storage products.

Switch recently broke ground on Gigawatt 1, a huge project that will use solar panels from First Solar to generate a total of 555 megawatts (MWs) of power at three locations and Tesla Megapacks to store the energy.
