With virtually all of China shutdown and under quarantine due to the coronavirus, the Chinese IT hardware market will suffer a temporary but significant impact in the first quarter due to demand not being met. While foreign impact is not certain, it does have the potential to spill over into other markets.
IDC now predicts the total 2020 server growth rate will be reduced from original growth projections of 12.4% to 7.4%, and Q1 sales will drop 15% from the same time period last year instead of the original projection of 16.5% growth.
Storage 2020 growth rate will be reduced from 12.5% to 7.3% and Q1 will be down 20% instead of the original projection of 16.6% growth over Q1 2019. The 2020 networking growth rate has been reduced from the original 6.2% to 3.0%.
Google Cloud this week bought a mainframe cloud-migration service firm Cornerstone Technology with an eye toward helping Big Iron customers move workloads to the private and public cloud.
Google said the Cornerstone technology – found in its G4 platform – will shape the foundation of its future mainframe-to-Google Cloud offerings and help mainframe customers modernize applications and infrastructure.
“Through the use of automated processes, Cornerstone’s tools can break down your Cobol, PL/1, or Assembler programs into services and then make them cloud native, such as within a managed, containerized environment” wrote Howard Weale, Google’s director, Transformation Practice, in a blog about the buy.
Hard drive makers are staving off obsolescence to solid-state drives (SSDs) by offering capacities that are simply not feasible in an SSD. Seagate and Western Digital are both pushing to release 20TB hard disks in the next few years. A 20TB SSD might be doable but also cost more than a new car.
But Showa Denko K.K. of Japan has gone one further with the announcement of its next-generation of heat-assisted magnetic recording (HAMR) media for hard drives. The platters use all-new magnetic thin films to maximize their data density, with the goal of eventually enabling 70TB to 80TB hard drives in a 3.5-inch form factor.
Showa Denko is the world’s largest independent maker of platters for hard drives, selling them to basically anyone left making hard drives not named Seagate and Western Digital. Those two make their own platters and are working on their own next-generation drives for release in the coming years.
If the industry needed more evidence that IoT devices and applications are taking over the world, Cisco this week said that by 2023 machine-to-machine communications will make up 50% or about 14.7 billion of all networked connections compared to 33% (6.1 billion) in 2018 and 3.1 percent in 2017.
The M2M findings were just a part of Cisco’s annual forecast of networking trends now called the Cisco Annual Internet Report. The report replaces the Visual Networking Index (VNI) Forecast and looks at everything from 5G and Wi-Fi growth to broadband trends collected from actual network traffic reports and independent analyst forecasts.
In my most recent blog post, I talked about the difficulty SD-WAN vendors have in finding their voice and clearly differentiating their value. My point was that if Wendy’s, Burger King, and McDonald’s could figure out how to differentiate their burgers and fries, we should be able articulate why customers choose our solutions over the 60+ vendors competing for their business. I started out talking about the business reasons why companies select Silver Peak. Now it’s time to talk about our differentiation at a product level.
How is our SD-WAN edge platform, Unity EdgeConnect™, unique? I’ll frame the differentiation around what our customers are telling us. You’ll notice a significant emphasis on our ability to improve application performance for any type of application traversing any type of transport. We’re the only company that first tries to fix problems with the underlying network, allowing customers to fully leverage all of their circuits, even in instances of degraded performance. Unlike others, we don’t just re-route packets in the event of transport brownouts and blackouts.
There are a number of commands for finding files on Linux systems, but there are also a huge number of options that you can deploy when looking for them.
For example, you can find files not just by their names, but by their owners and/or groups, their age, their size, the assigned permissions, the last time they were accessed, the associated inodes and even whether the files belong to an account or group that no longer exists on the system and so on.
You can also specify where a search should start, how deeply into the file system the search should reach and how much the search result will tell you about the files it finds.
Scientists have long envisioned brain-sensing technology that can translate thoughts into digital commands, eliminating the need for computer-input devices like a keyboard and mouse. One company is preparing to ship its latest contribution to the effort: a $399 development package for a noninvasive, AI-based, brain-computer interface.
Increasing cloud adoption as well as improved network security, visibility and manageability are driving enterprise software-defined WAN (SD-WAN) deployments at a breakneck pace.
According to research from IDC, software- and infrastructure-as-a-service (SaaS and IaaS) offerings in particular have been driving SD-WAN implementations in the past year, said Rohit Mehra, vice president, network infrastructure at IDC.
For example, IDC says that its recent surveys of customers show that 95% will be using SD-WAN technology within two years, and that 42% have already deployed it. IDC also says the SD-WAN infrastructure market will hit $4.5 billion by 2022, growing at a more than 40% yearly clip between now and then.
The era of NVMe-over-Fabrics (NVMe-oF™) is quickly approaching. By 2025, most data centers will likely have adopted NVMe-oF for some part of their architecture1. Accessing data from a shared storage system will be essentially as fast and as low latency as accessing data from direct attached storage (DAS). The year 2025 seems like a lifetime from now but the reality is it will be here before you know it.
Here are some of the top questions we hear from customers about this emerging technology. In this blog, our data center experts offer their responses, and point you to additional resources for understanding both the NVMe™ protocol and the fabric that stitches it together.
When SD-WAN was introduced, it was widely seen as an MPLS alternative. Today just about any credible, Internet-based SD-WAN solution can be used to replace a regional MPLS network. The bigger question is what happens the day after you networked your regional offices.
How will your SD-WAN deliver predictable application experience overseas or where Internet routing is unpredictable? How will your SD-WAN adapt to the cloud and mobile users, the new tenants of the modern enterprise? In short, understanding how your SD-WAN will accommodate the unpredictable is essential if you hope to future-proof your WAN.
In 1969, the very first e-message was sent over the ARPANET from computer science Professor Leonard Kleinrock's UCLA laboratory to a network node located at Stanford. That event kicked off a digital revolution that has utterly transformed our world. And ever since that first defining moment, the one question that has driven nearly all subsequent digital innovation has been: “How can we do this even faster?”
We are still wrestling with that same challenge today. The latest advances in computing, such as edge device hyperconnectivity and the hyperscalability achievements of advanced data center architectures are the result of the desire to achieve better performance. Speed is the driving force behind the digital transformation of today’s business infrastructures. It enables access to critical data and resources, drives business efficiencies, scales application development, increases productivity, generates revenue, and accelerates ROI.
IBM says it is consolidating its Storwize and the Flash Systems lines of storage products under a single family, the FlashSystem, that will span from entry level to advanced. It also announced a trio of all-flash storage products, spanning a range of use cases.
Eric Herzog, chief marketing officer and vice president of worldwide storage channels for IBM storage, made the announcing in a pair of blog posts here and here. He noted that different organizations have different requirements for storage, and that storage vendors have traditionally responded with unique storage platforms to meet them
With the combined challenges of tight IT budgets and scarcer technical talent, it’s becoming imperative for enterprise network pros to embrace automation of processes and the way infrastructure responds to changing network traffic.
Not only can automation help address these problems, they can also improve overall application-response time by anticipating and addressing looming congestion. Modern applications, such as virtual reality and artificial intelligence, and architectures that incorporate IoT and hybrid cloud have yet to reach their true potential because network capacity seems to always lag behind demand.
A common problem is that too much networking infrastructure is still manually maintained and managed, but major vendors are starting to addressing these issues, as are startups that seek to break bottlenecks through automation.
Not unlike nslookup in function, but with a lot more options, the dig command provides information that name servers manage and can be very useful for troubleshooting problems. It’s both simple to use and has lots of useful options.
The name “dig” stands for “domain information groper” since domain groping is basically what it does. The amount of information that it provides depends on a series of options that you can use to tailor its output to your needs. Dig can provide a lot of detail or be surprisingly terse.
Just the IP, please
To get just the IP address for a system, add the +short option to your dig command like this:
The popularity of Amazon’s cloud computing platform continues to grow. That means that opportunities for IT professionals in this sector are likely to be plentiful, but only those with the proper skills will be considered for jobs. So, if you're trying to climb above the competition, you'd be remiss to look over the AWS Solutions Architect Certification Bundle, currently discounted by over 90% today.
Global server sales had been projected to grow by 1.2% compared to the most recent quarter, but the chaos wrought by the coronavirus in China will cause sales to decline 9.8% sequentially, according to DigiTimes Research.
DigiTimes is an IT publication based in Taiwan. Its proximity to Taiwanese and Chinese vendors gives it some good sources, but it can also be way off target. However, the signs are piling up that coronavirus is causing some real mayhem.
For example, DigiTimes also reported that less than 20% of Chinese factory employees would return to work after an extended Lunar New Year break due to the coronavirus outbreak, and that many components plants in China have decided not to restart production until February 25.
We've seen many transformative changes in the market over the past few years. In 2019, for example, we witnessed router-centric and basic SD-WAN offerings beginning to fall short of expectations as enterprises began shifting toward a business-first networking model. We also saw an emphasis on cloud security, along with a bond forming between SD-WAN and UCaaS. We began to see a new set of emerging requirements for multi-cloud deployments, and the promise of 5G beginning to materialize.
So, what's in store for 2020? This is sure to mark another year of continued WAN transformation and a year in which enterprises can begin to realize a multiplier effect from their cloud investments. As the market continues to gain momentum, here are my annual predictions for SD-WAN and the future of the WAN edge infrastructure market.
Everyone watching Super Bowl 2020 witnessed the excitement that filled Hard Rock Stadium, as the Kansas City Chiefs became this year’s champions. (I was cheering hard for the 49ers but want to offer hearty congratulations to the new champs.) What wasn’t visible to the public—yet was omnipresent throughout the venue—was Wi-Fi connectivity that gave fans an enhanced experience during the game.
Whether it’s in a hospital, an office building, a university auditorium or a stadium, Wi-Fi scale matters. In hospitals, gameday is every day, and healthcare wireless networks play a vital role. Stadiums don’t always have gameday, but when they do, the WiFi has to work without a glitch.
2020! What could better motivate you to push ahead with your resolutions and organization’s digital transformation than a new year AND a new decade. As you put together your digital strategy, check out a new transformation-empowering (and transformational) technology category Gartner coined the Secure Access Service Edge or SASE (pronounced “Sassy”). SASE converges wide area networking and identity-based security into a cloud service targeted directly to your branch offices, mobile users, cloud services, and even IoT devices, wherever they happen to be. The result: consistently high WAN performance, security, productivity, agility, and flexibility across the global, mobile, cloud-enabled enterprise.
People skilled in the use of cloud based platforms are in demand. If you want to transition your career path into this specialized field, then The Complete 2020 Microsoft Azure Certification Prep Bundle, discounted by over 90 percent, may be the most convenient route.
This package is ideal for anyone who wants to work in the growing cloud computing sector. It includes eleven beginner-friendly courses that introduce students to the popular Microsoft Azure platform as well as advanced topics in data analysis, security, and integration. And, since it’s all delivered via the web, it’s far more affordable when compared with other forms of education.
Man pages provide essential information on Linux commands and many users refer to them often, but there’s a lot more to the man pages than many of us realize.
You can always type a command like “man who” and get a nice description of how the man command works, but exploring commands that you might not know could be even more illuminating. For example, you can use the man command to help identify commands to handle some unusually challenging task or to show options that can help you use a command you already know in new and better ways.
Let’s navigate through some options and see where we end up.
Using man to identify commands
The man command can help you find commands by topic. If you’re looking for a command to count the lines in a file, for example, you can provide a keyword. In the example below, we’ve put the keyword in quotes and added blanks so that we don’t get commands that deal with “accounts” or “accounting” along with those that do some counting for us.
IoT equipment designers shooting for efficiency should explore the potential for using buildings as antennas, researchers say.
Environmental surfaces such as walls can be used to intercept and beam signals, which can increase reliability and data throughput for devices, according to MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL).
Researchers at CSAIL have been working on a smart-surface repeating antenna array called RFocus. The antennas, which could be applied in sheets like wallpaper, are designed to be incorporated into office spaces and factories. Radios that broadcast signals could then become smaller and less power intensive.
The ease with which internet of things devices can be compromised, coupled with the potentially extreme consequences of breaches, have prompted action from legislatures and regulators, but what group is best to decide?
Both the makers of IoT devices and governments are aware of the security issues, but so far they haven’t come up with standardized ways to address them.
“The challenge of this market is that it’s moving so fast that no regulation is going to be able to keep pace with the devices that are being connected,” said Forrester vice president and research director Merritt Maxim. “Regulations that are definitive are easy to enforce and helpful, but they’ll quickly become outdated.”
The only thing constant is change, and data centers are no exception. As data architects attempt to anticipate future data center needs – while delivering the required SLAs to the business – the solution is often to over-provision resources so that the infrastructure can absorb any changes or periodic spikes in demand.
But today change happens much more frequently, whether it’s onboarding new applications or reaching new heights in data growth. Most often, organizations expect immediate implementation of those changes In today’s environment of flat or declining budgets, IT can no longer afford to over-provision its way.
Composable disaggregated infrastructure (CDI) enables organizations to respond to changes almost instantly while at the same time reduce costs. This in turn helps IT better align changing business needs and allocate IT resources on the fly.
VMware is increasing its CPU licensing prices for customers running CPUs with more than 32 physical cores. Effective April 2, if CPUs with more than 32 cores are deployed, then customers need to purchase additional CPU licenses.
Such a change doesn't seem surprising. For the longest time, 32-core processors seemed like a pipe dream. Intel was hovering in the range of 20-odd cores, and AMD was a non-player. Then came the AMD Epyc with 32 cores in 2017, followed by Epyc 2 with 64 cores in 2019 .
Predictive maintenance is, arguably, the most hyped application of IoT technology currently available to the enterprise user, and it’s easy to understand why: Getting greater insight into industrial machinery, fleets of vehicles or anything else that can be digitally instrumented seems to offer a fairly direct path to savings through lower maintenance costs and less downtime.
But it’s not as simple as just grafting sensors onto existing equipment, according to experts, and reaping the benefits of predictive maintenance isn’t an automatic win for the asset-heavy businesses that can profit most from this IoT implementation.
