There are connectivity options aplenty for most types of IoT deployment, but the idea of simply handing the networking part of the equation off to a national licensed wireless carrier could be the best one for certain kinds of deployments in the medical field.Telehealth systems, for example, are still a relatively new facet of modern medicine, but they’re already among the most important applications that use carrier networks to deliver care. One such system is operated by the University of Mississippi Medical Center, for the treatment and education of diabetes patients.To read this article in full, please click here
The hybrid cloud market is expected to grow from $38.27 billion in 2017 to $97.64 billion by 2023, at a Compound Annual Growth Rate (CAGR) of 17.0% during the forecast period, according to Markets and Markets.The research firm said the hybrid cloud is rapidly becoming a leading cloud solution, as it provides various benefits, such as cost, efficiency, agility, mobility, and elasticity. One of the many reasons is the need for interoperability standards between cloud services and existing systems.Unless you are a startup company and can be born in the cloud, you have legacy data systems that need to be bridged, which is where the hybrid cloud comes in.To read this article in full, please click here
It’s June, so it’s that time again for the twice-yearly Top 500 supercomputer list, where bragging rights are established or, in most cases, reaffirmed. The list constantly shifts as new trends appear, and one of them might be a break in Intel’s dominance.Supercomputers in the top 10 list include a lot of IBM Power-based systems, and almost all run Nvidia GPUs. But there’s more going on than that.For starters, an ARM supercomputer has shown up, at #156. Astra at Sandia National Laboratories is an HPE system running Cavium (now Marvell) ThunderX2 processors. It debuted on the list at #204 last November, but thanks to upgrades, it has moved up the list. It won’t be the last ARM server to show up, either.To read this article in full, please click here
I am the proud owner of a Tesla, a recognized leader in electric vehicles, which makes my daily commute (of almost 3 hours) less stressful and more enjoyable. I also work for Silver Peak, recognized as a Leader in the 2018 Gartner Magic Quadrant for WAN Edge Infrastructure. Both Silver Peak and Tesla have unique positions in different markets. So, why should I make the tie between Tesla and Silver Peak? Not only do the two companies continue to innovate in their respective industries, they also continue to disrupt the status quo of the way things have worked for decades to make them work in today’s fast-paced world. Just as Tesla has transformed the automotive industry by developing the most innovative self-driving vehicle, at Silver Peak, we don’t think of SD-WAN just as a Software-Defined WAN, but as a self-driving wide area network that learns and adapts to keep pace with the changing requirements of today’s cloud-first enterprises.To read this article in full, please click here
10 of the world's fastest supercomputersImage by Henrik5000 / Getty ImagesThe TOP500 ranking of the fastest supercomputers in the world was announced today, with absolutely no change in the computers ranking in the top10 since the last semi-annual rating in June. Outside the top 10, though, there were changes, notably that it’s harder for a supercomputer to get on the TOP500 list at all: The lowest ranking supercomputer now delivers 1.14PFlop/sec, up from 1.02PFlop/sec in June. Overall, the aggregate performance of the entire TOP500 list sits at 1.65 exaflops. Check out the rest of this slideshow to see details on the current top-10-ranking machines.To read this article in full, please click here
It’s getting harder to find people to design, build and manage data centers.The sector is facing a staffing crisis, says Andy Lawrence, executive director of research at Uptime Institute, which just released its annual data-center survey. “We all know that that the data-center skills shortage is real. I think what we’re seeing in this data is that it’s getting a little worse,” Lawrence says.

There are several ways to send email from the Linux command line. Some are very simple and others more complicated, but offer some very useful features. The choice depends on what you want to do -– whether you want to get a quick message off to a co-worker or send a more complicated message with an attachment to a large group of people. Here's a look at some of the options:mail
The easiest way to send a simple message from the Linux command line is to use the mail command. Maybe you need to remind your boss that you're leaving a little early that day. You could use a command like this one:$ echo "Reminder: Leaving at 4 PM today" | mail -s "early departure" myboss

After a rather long period of silence, Oracle announced an update to its server line, the Oracle Exadata Database Machine X8, which features hardware and software enhancements that include artificial intelligence (AI) and machine learning capabilities, as well as support for hybrid cloud.Oracle acquired a hardware business nine years ago with the purchase of Sun Microsystems. It steadily whittled down the offerings, getting out of the commodity hardware business in favor of high-end mission-critical hardware. Whereas the Exalogic line is more of a general-purpose appliance running Oracle’s own version of Linux, Exadata is a purpose-built database server, and they really made some upgrades.To read this article in full, please click here
The energy storage capacity in uninterruptable power supply (UPS) batteries, languishing often dormant in data centers, could provide new revenue streams for those data centers, says Eaton, a major electrical power management company.Excess, grid-generated power, created during times of low demand, should be stored on the now-proliferating lithium-backup power systems strewn worldwide in data centers, Eaton says. Then, using an algorithm tied to grid-demand, electricity should be withdrawn as necessary for grid use. It would then be slid back onto the backup batteries when not needed.[ Read also: How server disaggregation can boost data center efficiency | Get regularly scheduled insights: Sign up for Network World newsletters ]
The concept is called Distributed Energy and has been gaining traction in part because electrical generation is changing—emerging green power, such as wind and solar, being used now at the grid-level have considerations that differ from the now-retiring, fossil-fuel power generation. You can generate solar only in daylight, yet much demand takes place on dark evenings, for example.To read this article in full, please click here
Just two months ago Dell EMC and Cisco renewed their converged infrastructure vows, and now the two have taken another step in the alliance. At this year’s at Cisco Live event taking place in San Diego, the two announced plans to expand VxBlock 1000 integration across servers, networking, storage, and data protection.This is done through support of NVMe over Fabrics (NVMe-oF), which allows enterprise SSDs to talk to each other directly through a high-speed fabric. NVMe is an important advance because SATA and PCI Express SSDs could never talk directly to other drives before until NVMe came along.To read this article in full, please click here
Networks were initially designed to create internal segments that were separated from the external world by using a fixed perimeter. The internal network was deemed trustworthy, whereas the external was considered hostile. However, this is still the foundation for most networking professionals even though a lot has changed since the inception of the design.More often than not the fixed perimeter consists of a number of network and security appliances, thereby creating a service chained stack, resulting in appliance sprawl. Typically, the appliances that a user may need to pass to get to the internal LAN may vary. But generally, the stack would consist of global load balancers, external firewall, DDoS appliance, VPN concentrator, internal firewall and eventually LAN segments.To read this article in full, please click here
SAN DIEGO— As many companies look to SD-WAN technology to reduce costs, improve connectivity and streamline branch office access, one of the key requirements will be solid security technologies to protect corporate resources.At its Cisco Live customer event here this week, the company took aim at that need by telling customers it added support for the its cloud-based security gateway – known as Umbrella – to its SD-WAN software offerings.

What are the options for security SD-WAN?
At its most basic, SD-WAN lets companies aggregate a variety of network connections – including MPLS, 4G LTE and DSL – into a branch or network-edge location and provides a management software that can turn up new sites, prioritize traffic and set security policies. SD-WAN's driving principle is to simplify the way big companies turn up new links to branch offices, better manage the way those links are utilized – for data, voice or video – and potentially save money in the process.To read this article in full, please Continue reading

Chinese IT hardware giant Huawei is in a very tough position now, cut off from most western technology partners following the Trump administration’s declaration of the firm as a national security risk. The question now becomes what do its customers do.The Trump administration issued an order that effectively bars American firms from selling components and software to the company, and very quickly Huawei was cut off from Intel, ARM, Infineon, Samsung, and Google. The SD Association and Wi-Fi Alliance have also cut ties with Huawei.However, Huawei got a temporary break last month when the Commerce Department gave the company a reprieve after it added Huawei to a list of companies it considered a national security risk. Instead, the department posted a notice to the Federal Register that it would grant 90-day permissions for transactions necessary to maintain and support existing cellular networks and handsets.To read this article in full, please click here
