Symbolic links play a very useful role on Linux systems. They can help you remember where important files are located on a system, make it easier for you to access those files and save you a good amount of disk space and trouble by making it unnecessary for you to copy large files just to make them a little more accessible.
What exactly is a symbolic link?
Generally referred to as a "symlink" or "soft link", symbolic links are very small files. In fact, all a symlink really contains is the name of whatever file it points to, generally along with the file system path (relative to the current location or absolute). If a file named ref1 points to a file named /apps/refs/ref-2020, ref1 will be 19 characters long even if the ref-2020 file is 2 terabytes. If it points to ./ref-2020, it will be only 10 characters in length. If it points to ref-2020, only eight.
Cisco is embracing the secure-access service edge (SASE) architecture put forth by Gartner with plans to upgrade some of its existing products to reach the goal of delivering access control, security and networking to cloud services.
The enterprise shift to SASE will be gradual as they figure out the best way to connect their increasingly remote workforce to distributed resources delivered from corporate data centers and as cloud services, Cisco says.
“Flexibility will be fundamental as IT chooses among multiple security and networking capabilities that best fit their operations, regulatory requirements, and types of applications,” said Jeff Reed, senior vice president of product, Cisco’s Security Business Group in a blog post. “Security services can be predominantly delivered from the cloud to provide consistent access policies across all types of endpoints. However, globally distributed organizations may need to apply security and routing services differently according to regional requirements.”
Cisco said it intends to acquire network intelligence software provider ThousandEyes for an undisclosed amount.
Founded in 2010, the 400-employee ThousandEyes firm offers a cloud-based software package that analyzes performance of local and wide-area networks and the internet. Utilizing its world-wide insights into service networks the company also tracks ISP, cloud and collaboration application performance via a family of intelligent cloud, enterprise and endpoint agents.
“ThousandEyes’ technology warns us when a user’s experience is less than ideal and can pinpoint where those failures were caused. With thousands of agents deployed throughout the Internet, ThousandEyes’ platform has an unprecedented understanding of the Internet and grows more intelligent with every deployment,” wrote Todd Nightingale, senior vice president and general manager with Cisco in a blog post about the acquisition.
Sales of all categories of Ethernet switches and routers were down 14% in the first quarter of 2020 compared to Q1 last year, the worst quarter in seven years, according to Synergy Research Group.
“In a pre-pandemic world we’d have expected total vendor revenues from switches and routers to have been a billion dollars higher that what we actually saw,” said John Dinsdale, a Chief Analyst at Synergy. Revenues for the quarter were $9.1 billion, down from $10.58 billion in last year’s first quarter.
The problem wasn’t entirely that COVID-19 forced businesses to change plans about buying the gear. “On balance the Q1 hit was driven more by supply-chain issues rather than by soft demand,” he said. Demand is still high from service providers, but not so for enterprises, where “some sectors will take several months before returning to some form of normality.” He said the supply-chain problems should be resolved relatively quickly.
The technology research company Gartner recently released its worldwide server market report for 2019. According to the report, Huawei ranks No. 1 in 4-socket (4S) rack server shipments in both the global and China markets, thanks to the continued success of its FusionServer Pro series.
The Huawei FusionServer Pro V5 series servers comprise the 2488 V5, 2488H V5, and 5885H V5 4-socket servers, which all run on the Intel® Xeon® Scalable Processor platform as well as Huawei’s leading reliability, availability, and serviceability (RAS) features and Fault Diagnosis System (FDM). Each model is designed to answer the pain points of different application scenarios, but all provide accurate and immediate response to fault alarms. FusionServer Pro V5 delivers industry-leading availability, serviceability, and reliability, making it a smart choice for those running large databases, ERP, CRM, big data analysis, high-performance computing, or virtualization applications.
Security and performance concerns made it challenging for TrialCard to enable its employees to work from home when the COVID-19 pandemic hit.
Customer service agents use a voice-over-IP phone and thin-client computer, both of which were designed to work in an on-premises office environment. "They need those systems to do their day-to-day job," says Ryan Van Dynhoven, director of infrastructure at TrialCard, a Morrisville, N.C.-based company that helps pharmaceutical manufacturers connect with patients, including providing patient support and clinical trial services.
As COVID-19 continues to spread, forcing employees to work from home, the services of ISPs, cloud providers and conferencing services a.k.a. unified communications as a service (UCaaS) providers are experiencing increased traffic.
ThousandEyes is monitoring how these increases affect outages and the performance challenges these providers undergo. It will provide Network World a roundup of interesting events of the week in the delivery of these services, and Network World will provide a summary here. Stop back next week for another update, and see more details here.
Fujitsu has delivered all the components needed for a supercomputer in Japan that is expected to break the exaFLOP barrier when it comes online next year, and that delivery means that the same class of hardware will be available soon for enterprise customers.
The supercomputer, called Fugaku, is being assembled and brought online now at the RIKEN Center for Computational Science. The installation of the 400-plus-rack machine started in December 2019, and full operation is scheduled for fiscal 2021, according according to a Fujitsu spokesman.
All told, Fugaku will have a total of 158,976 processors, each with 48 cores at 2.2 GHz. Already the partially deployed supercomputer’s performance is half an exaFLOP of 64-bit double precision floating point performance and looks to be the first to get to a full exaFLOP. Intel says its supercomputer Aurora being built for the Department of Energy’s Argonne National Laboratory in Chicago will be delivered by 2021, and it will break the exaFLOP barrier, too.
With more of us connecting with our healthcare providers virtually during the coronavirus pandemic, hackers may find it more appealing to attack medical or hospital systems. Increased amounts of data due to telemedicine and medical internet of things (IoT) devices must be secure to protect individuals’ privacy and for HIPAA compliance. Network World senior writer Jon Gold joins Juliet to discuss medical IoT security risks, why these attacks may or may not be especially prevalent now and how to mitigate IoT security risks.
About one year ago, Dell EMC announced a new on-premises offering called Dell Technologies Cloud, using the company’s hyper-converged infrastructure VXRail and VMware Cloud Foundation, VMware’s hybrid cloud solution that provides integration between public and private clouds.
This week, Dell rolled out a storage partnership with Google Cloud through the launch of a service called Dell Technologies Cloud OneFS for Google Cloud, designed to help organizations control data growth and ease the movement of files between their private clouds and Google Cloud.
OneFS for Google Cloud combines the Dell EMC Isilon file-storage appliance with Google Cloud’s analytics and compute services. It allows companies to access applications and move workloads as large as 50 petabytes in a single filesystem between on-premises Dell storage systems and Google Cloud. Citing its own benchmarks, Dell claims OneFS delivered sustainable read throughput of 200GB/s and write throughput of 120GB/s.
The tmux tool is one of a number of Linux terminal window splitters that allow you to run commands in adjacent (up/down, right/left or both) panes so that you can easily use the output in one pane to help with work you’re doing in another. You can even disconnect a multi-pane tmux session and reattach to it when you need it again.
What's more, processes running within tmux will continue running even when you detach, making tmux an excellent tool to use when you’re not sure your connection to a remote server is solid and don't want to be dropped in the middle of an important task.
The coronavirus pandemic has accelerated some companies' plans to adopt secure access service edge (SASE).
Last summer, Gartner estimated SASE adoption at less than 1% of enterprises and said it would take five to 10 years before the technology reaches mainstream. But today, SASE is one of the main topics of client interest, according to Gartner analyst John Wheeler.
IoT sensors that monitor body temperature, in real-time and implemented at scale, could provide geolocation data that would allow potential quarantine areas to be rapidly identified, perhaps even instantaneously. The idea is to shut down emerging viruses before a pandemic could take hold.
IoT security firm WISeKey says it's working on such a solution. "Using the network of billions of interconnected smart IoT sensors, we can detect the spread of viruses by combining the anonymized digital identity with the behavior of a person," WISeKey said in a press release. Importantly, the company claims its solution can be fully secured and trusted.
Last year, Lenovo Data Center Group (DCG) announced single-socket ThinkSystem servers using the AMD Rome generation, which has up to 64 cores per processor. Dual-socket systems are de rigueur in enterprise servers, but that's because those processors have just 20-odd cores. AMD's pitch, which Lenovo and its competitors embraced, was that it could offer more compute in a one-socket, 64-core processor than two 22-core processors, and for less money.
This year Lenovo DGC is following up that launch with the 1U ThinkSystem SR645 and 2U ThinkSystem SR665 two-socket servers, featuring enhanced performance and I/O connectivity for higher performance workloads. With 128 cores/256 threads in a 1U/2U design, a whole lot of computation power can be squeezed into a small space.
Cisco has upgraded its core networking software to include better support for enterprise multicloud integration and management as well as tools to help telcos or hyperscalers tie together large scale data-center networks.
The new features are part of the 5.0 release of Cisco's Application Centric Infrastructure (ACI) software, which runs on the company's core data center Nexus 9000 systems.
The mere fact of the COVID pandemic’s existence has pushed the American healthcare system to capacity, but another threat to that system has reared its ugly head – cyberattacks, particularly those based on ransomware, have become more common as the disease spread, targeting medical IoT devices and healthcare networks.
According to Forrester Research analyst Chris Sherman, two U.S. hospitals have already been attacked via virtual care systems, after a hacker targeted a vulnerability in a medical IoT device (specifically, a remote patient-monitoring sensor) and gained access to the hospitals’ patient databases. And in another type of attack, the Fresenius Group, a medical device maker and the largest private hospital operator in Europe, has been hit by ransomware.
Schneider Electric has partnered with systems management company Aveva to put together a package for managing multiple and hyperscale data centers with a single view to enable and expand visibility into day-to-day operations.
The package combines Aveva Unified Operations Center with Schneider Electric’s EcoStruxure for control and monitoring systems to offer predictive maintenance, staff training and financial aspects of large data centers. The combined software provides a homogenous view of engineering, operations and performance and improves workforce productivity by standardizing and de-siloing systems and processes across multiple sites for real-time decision making.

Update 5/21/2020: AT&T Inc. says it will stop using the phrases "5G Evolution" and "5G Evolution, The First Step to 5G" in marketing its 4G LTE network that provides 5G speeds, according to CNN. The National Advertising Review Board recommended the change, saying the language "will mislead reasonable customers" into thinking they're buying a 5G servivce. AT&T said in a statement that it "respectfully disagrees" with the recommendation but said it would comply.
Aiming to help customers handle growing on-premises workloads, VMware and Dell EMC have bolstered their co-developed cloud software.
First introduced in 2018, VMware Cloud on Dell EMC is intended to help enterpise customers move on-premises infrastructure and workloads to the cloud. Version 2.0 of VMware Cloud on Dell EMC bri-gs improved support for high-density and high-performance data-center applications.
VMware Cloud on Dell EMC consists of VMware’s high-performance compute, storage and networking software, powered by VMware vSphere, vSAN and NSX, tightly integrated with Dell EMC VxRail hyperconverged infrastructure (HCI) hardware, and delivered as a service all – managed by VMware.
Given the continued growth in capacity and performance of enterprise SSDs, it would seem mechanical hard disk drives are set to fade out eventually. But if they do, it won't be any time soon. Cloud storage provider Backblaze’s quarterly drive performance report shows that hard disks have remarkable resilience despite the abuse they take.
Backblaze has storage pods in data center colocations that include more than 129,000 HDDs from various manufacturers, ranging in capacity from 4TB to 16TB. With that many drives deployed, Backblaze has a unique perspective on the durability of different hard drives.
Nvidia, whose heritage lies in making chips for gamers, has announced its first new GPU architecture in three years, and it’s clearly designed to efficiently support the various computing needs of artificial intelligence and machine learning.
The architecture, called Ampere, and its first iteration, the A100 processor, supplant the performance of Nvidia’s current Volta architecture, whose V100 chip was in 94 of the top 500 supercomputers last November. The A100 has an incredible 54 billion transistors, 2.5 times as many as the V100.
Tensor performance, so vital in AI and machine learning, has been significantly improved. FP16 floating point calculations are almost 2.5x as fast as V100 and Nvidia introduced a new math mode called TF32. Nvidia claims TF32 can provide up to 10-fold speedups compared to single-precision floating-point math on Volta GPUs.
Juniper intends to spread the gospel of artificial intelligence across enterprise networking in the coming months with new products and services.
The expected moves are a continuation of a strategy that has been an integral part of Juniper since the company bought wireless and artificial-intelligence software maker Mist in 2019 for $405 million.
Mist’s cloud-based Wi-Fi Assurance system includes an AI-base engine called Marvis that features dynamic packet capture and machine learning to automatically identify, adapt to and fix network issues.
