The concept of using passive optical LANs in enterprise campuses has been around for years, but hasn’t taken off because most businesses consider all-fiber networks to be overkill for their needs. I’ve followed this market for the better part of two decades, and now I believe we’re on the cusp of seeing POL go mainstream, starting in certain verticals.The primary driver of change from copper to optical is that the demands on the network have evolved. Every company now considers its network to be business critical where just a few years ago, it was considered best effort in nature. Downtime or a congested network meant inconvenienced users, but today they mean the business is likely losing big money.To read this article in full, please click here
Linux systems provide a very easy-to-use command for breaking files into pieces. This is something that you might need to do prior to uploading your files to some storage site that limits file sizes or emailing them as attachments. To split a file into pieces, you simply use the split command.$ split bigfile
By default, the split command uses a very simple naming scheme. The file chunks will be named xaa, xab, xac, etc., and, presumably, if you break up a file that is sufficiently large, you might even get chunks named xza and xzz.[Get regularly scheduled insights by signing up for Network World newsletters.]
Unless you ask, the command runs without giving you any feedback. You can, however, use the --verbose option if you would like to see the file chunks as they are being created.To read this article in full, please click here
Seagate has taken the wraps off its Exos 2X14 enterprise hard drive. It's the first to integrate Seagate's MACH.2 multi-actuator technology, which is a method of turning one hard disk into two and doubling performance.The technology is pretty straightforward. Say you have four platters in a disk drive. The actuator controls the drive heads and moves them all in unison over all four platters. Seagate's multi-actuator makes two independent actuators out of one, so in a six-platter drive, the two actuators cover three platters each.

The venerable VPN, which has for decades provided remote workers with a secure tunnel into the enterprise network, is facing extinction as enterprises migrate to a more agile, granular security framework called zero trust, which is better adapted to today’s world of digital business.VPNs are part of a security strategy based on the notion of a network perimeter; trusted employees are on the inside and untrusted employees are on the outside. But that model no longer works in a modern business environment where mobile employees access the network from a variety of inside or outside locations, and where corporate assets reside not behind the walls of an enterprise data center, but in multi-cloud environments.To read this article in full, please click here

Inphi, a developer of high-speed data interconnects, announced it has begun sampling its new Canopus coherent digital signal processor (DSP), which it claims reduces power draw by up to 75 percent and triples the throughput of data over fiber networks, especially over long distances.The Canopus processor comes on a plug-in module about the size of a cigarette lighter that goes in existing networking equipment. The chip is built on a 7nm manufacturing process, and its silicon geometry delivers over 75 percent reduction in DSP power dissipation and size as compared to the current generation of coherent DSPs.Coherent optical transmission is a technique for transporting considerably more information through a fiber optic cable, and is especially popular when transporting over long distances. It uses modulation and phases of the light to amplify transmission. A DSP is often needed to manage and clean up the photonics.To read this article in full, please click here
Nvidia was all over Supercomputing 19 last week, not surprisingly, and made a lot of news which we will get into later. But overlooked was perhaps the most interesting news of all: a new generation graphics-acceleration card that is faster and way more power efficient.Multiple attendees and news sites spotted it at the show, and Nvidia confirmed to me that this is indeed a new card. Nvidia’s “Volta” generation of Tesla GPU-accelerator cards has been out since 2017, so an upgrade was well overdue.[Get regularly scheduled insights by signing up for Network World newsletters.]
The V100S comes only in PCI Express 3 form factor for now but is expected to eventually support Nvidia’s SXM2 interface. SXM is a dual-slot card design by Nvidia that requires no connection to the power supply, unlike the PCIe cards. SXM2 allows the GPU to communicate either with each other or to the CPU through Nvidia’s NVLink, a high-bandwidth, energy-efficient interconnect that can transfer data up to ten times faster than PCIe.To read this article in full, please click here
The date command on Linux systems is very straightforward. You type “date” and the date and time are displayed in a useful way. It includes the day-of-the-week, calendar date, time and time zone:$ date
Tue 26 Nov 2019 11:45:11 AM EST
As long as your system is configured properly, you’ll see the date and current time along with your time zone.[Get regularly scheduled insights by signing up for Network World newsletters.]
The command, however, also offers a lot of options to display date and time information differently. For example, if you want to display dates in the most useful format for sorting, you might want to use a command like this:To read this article in full, please click here
Better quantum algorithms and a strange silence since last year from quantum computing researchers suggest that we are closer to breaking traditional encryption than most people believe.
As artificial intelligence takes off in enterprise settings, so will data center power usage. AI is many things, but power efficient is not one of them.For data centers running typical enterprise applications, the average power consumption for a rack is around 7 kW. Yet it’s common for AI applications to use more than 30 kW per rack, according to data center organization AFCOM. That’s because AI requires much higher processor utilization, and the processors – especially GPUs – are power hungry. Nvidia GPUs, for example, may run several orders of magnitude faster than a CPU, but they also consume twice as much power per chip. Complicating the issue is that many data centers are already power constrained.To read this article in full, please click here

For the Internet of Things to become ubiquitous, many believe that inefficiencies in the powering of sensors and radios has got to be eliminated. Battery chemistry just isn’t good enough, and it’s simply too expensive to continually perform truck-rolls, for example, whenever batteries need changing out. In many cases, solar battery-top-ups aren’t the solution because that, usually-fixed, technology isn’t particularly suited to mobile, or impromptu, ad hoc networks.Consequently, there’s a dash going on to try to find either better chemistries that allow longer battery life or more efficient chips and electronics that just sip electricity. An angle of thought being followed is to wake-up network radios only when they need to transmit a burst of data. Universities say they are making significant progress in this area.To read this article in full, please click here

It has been a long time since I shared an office with Nir Zuk, the co-founder and CTO of Palo Alto Networks (PAN). Back in 1998, at Check Point’s office in San Francisco, it was early days for the network security company co-founded by Gil Shwed, Marius Nacht, and me. Since then, Nir launched PAN, which became a global leader in network security. I was honored to support Nir and the PAN team early in their journey.Last week, our paths converged again. This time, we shared a vision for the future of networking and security. On the stage of PAN’s annual event, Nir presented PAN’s vision of a converged cloud-based architecture that will displace the legacy appliance stack of today. Nir did a great job advocating for the convergence of the numerous point solutions piled in IT departments everywhere.To read this article in full, please click here
