SD-WAN: What is it and why you’ll use it one day

There have been significant changes in wide-area networks over the past few years, none more important than software-defined WAN or SD-WAN, which is changing how network pros think about optimizing the use of connectivity that is as varied as Multiprotocol Label Switching (MPLS), frame relay and even DSL.What is SD-WAN? As the name states, software-defined wide-area networks use software to control the connectivity, management and services between data centers and remote branches or cloud instances. Like its bigger technology brother, software-defined networking, SD-WAN decouples the control plane from the data plane.To read this article in full, please click here

The biggest risk to uptime? Your staff

There was an old joke: "To err is human, but to really foul up you need a computer." Now it seems the reverse is true. The reliability of data center equipment is vastly improved but the humans running them have not kept up and it's a threat to uptime.The Uptime Institute has surveyed thousands of IT professionals throughout the year on outages and said the vast majority of data center failures are caused by human error, from 70 percent to 75 percent.[Get regularly scheduled insights by signing up for Network World newsletters. ] And some of them are severe. It found more than 30 percent of IT service and data center operators experienced downtime that they called a “severe degradation of service” over the last year, with 10 percent of the 2019 respondents reporting that their most recent incident cost more than $1 million.To read this article in full, please click here

Viewing files and processes as trees on Linux

Linux provides several handy commands for viewing both files and processes in a branching, tree-like format that makes it easy to view how they are related. In this post, we'll look at the ps, pstree and tree commands along with some options they provide to help focus your view on what you want to The ps command that we all use to list processes has some interesting options that many of us never take advantage of. While the commonly used ps -ef provides a complete listing of running processes, the ps -ejH command adds a nice effect. It indents related processes to make the relationship between these processes visually more clear  – as in this excerpt:To read this article in full, please click here

Reimagining-the-Internet project gets funding

The Internet of Things and 5G could be among the benefactors of an upcoming $20 million U.S. government cash injection designed to come up with new architectures to replace existing public internet.FABRIC, as the National Science Foundation-funded umbrella project is called, aims to come up with a proving ground to explore new ways to move, keep and compute data in shared infrastructure such as the public internet. The project “will allow scientists to explore what a new internet could look like at scale,” says the lead institution, the University of North Carolina at Chapel Hill, in a media release.

Early adopter finds SD-WAN yields better management, costs, uptime

Managing the Wide Area Network (WAN) for Redmond Inc., a supplier of industrial and commercial products – from salt that’s used to protect winter roadways to organic dairy products and health items – is an easier job today for the company’s technical project manager Aaron Gabrielson than it was a year ago.Redmond manages a phone system, point of sale and fax centrally out of headquarters in Heber City, Utah, which means each of Redmond’s 10 branch sites across the Midwest need a reliable connection back to headquarters in Utah. That’s easier for some sites, like those in Salt Lake City, than others, such as rural areas where there may only be a handful of workers on a farm.To read this article in full, please click here

Is hybrid cloud certification right for you?

After years of shifting applications to the public cloud, enterprises realize it’s not the right fit for every app and are pulling some of them back to private clouds, forcing the businesses to adopt a hybrid strategy. But it’s not an easy process and one that may require formal training and certifications for the  IT pros tasked with this important transition.“A huge desire to move to the cloud, and pressure from lines of business to move to the cloud, have created an experience gap that has led to serious missteps and forced IT teams to repatriate workloads they had put in the cloud back into the data center,” says Scott Sinclair, senior analyst at IT research firm ESG. “IT’s level of competence, experience, and education in how to integrate with the cloud is woefully inadequate.”To read this article in full, please click here

Intel announces Optane for workstations, higher capacity NAND

At its Memory and Storage Day 2019 in Seoul last week, Intel made several announcements concerning its Optane persistent storage as well as NAND flash capacity.Optane is a new form of non-volatile memory from Intel that has the storage capacity of a solid state drive (SSD) but speed almost equal to DRAM. It sits between memory and storage to act as a large, fast cache. While some come in a PCI Express card design, the predominant design is DRAM memory sticks that plug into the motherboard. And they cost a fortune. A 512GB Optane stick will run you $8,000.See how AI can boost data-center availability and efficiency Intel announced a new generation of Optane memory codenamed "Alder Stream," which it said has a 50x lower failure rate than 3D NAND and also triples the transfers per second compared to the current generation of Optane on the market today.To read this article in full, please click here

BrandPost: Westcon-Comstor Builds a more Visible WAN

For Michael Soler, a senior infrastructure manager at Westcon-Comstor, a major IT distributor, moving to a software-defined wide-area network (SD-WAN) was as much about taking control of the network as it was about saving money.The move accomplished both, according to Soler. “It’s been a very successful story,” says Soler. “We have gained visibility, and this means control. I can see which users are using which applications, and we can look at bandwidth. We wanted to save money and we greatly succeeded.”Of course, there is more to the story than that. Soler says moving to an SD-WAN platform, built by Silver Peak, accomplished many goals at once. These included:To read this article in full, please click here

Data center gear will increasingly move off-premises

I've said that colocation and downsizing in favor of the cloud is happening, and the latest research from 451 Research confirms the trend. More than half of global utilized racks will be located at off-premises facilities, such as cloud and colocation sites, by the end of 2024, the company found.As companies get out of data center ownership, hardware will move to colocation sites like Equinix and DRT or cloud providers. The result is the total worldwide data center installed-base growth will see a dip of 0.1% CAGR between 2019-2024, according to the report, but overall total capacity in terms of space, power, and racks will continue to shift toward larger data centers.To read this article in full, please click here
