BrandPost: Introducing the Adaptive Network Vision

Why now? The networking industry is being disrupted.There is an explosion in network demand, driven by ultramobile users who want the ability to access the cloud and consume high-definition content, video, and applications when and where they choose. This disruption of the network will only be exacerbated by the adoption of the Internet of Things (IoT) and 5G, the use of which involves billions of devices interacting with machines, users, and clouds to drive consumer and business interactions.For instance, what happens when users want to engage in a 4K-based virtual reality session hosted in the cloud, while traveling at high speed in their driverless cars? What happens when the physical devices currently used to support networking functions become virtual—and so do the user end-points? Network providers are now realizing the level of complexity and variability this type of demand will introduce, and that their current networks are not up to the challenge.To read this article in full, please click here

Riga, Tallinn and Vilnius: Launching three new European Cloudflare data centers

Cloudflare announces the turn up of our newest data centers located in Riga (Latvia), Tallinn (Estonia) and Vilnius (Lithuania). They represent the 140th, 141st and 142nd cities across our growing global network, and our 37th, 38th, 39th cities in Europe. We are very excited to help improve the security and performance of over 7 million Internet properties across 72 countries including the Baltic states.

We will be interconnecting with local networks over multiple Internet exchanges: Baltic Internet Exchange (BALT-IX), Lithuanian Internet eXchange Point (LIXP), LITIX, Tallinn Internet Exchange (TLLIX), Tallinn Governmental Internet Exchange (RTIX), Santa Monica Internet Local Exchange (SMILE-LV), and potentially, the Latvian Internet Exchange (LIX-LV).

If you are an entrepreneur anywhere in the world selling your product in these markets, or a Baltic entrepreneur reaching a global audience, we've got your back.

Of the five countries that in the drainage basin but do not border the sea, Cloudflare has deployments Continue reading

Nvidia packs 2 petaflops of performance in a single compact server

At its GPU Technology Conference this week, Nvidia took the wraps off a new DGX-2 system it claims is the first to offer multi-petaflop performance in a single server, thus greatly reducing the footprint to get to true high-performance computing (HPC).DGX-2 comes just seven months after the DGX-1 was introduced, although it won’t ship until the third quarter. However, Nvidia claims it has 10 times the compute power as the previous generation thanks to twice the number of GPUs, much more memory per GPU, faster memory, and a faster GPU interconnect.[ Learn how server disaggregation can boost data center efficiency. | Get regularly scheduled insights by signing up for Network World newsletters. ] The DGX-2 uses a Tesla V100 CPU, the top of the line for Nvidia’s HPC and artificial intelligence-based cards. With the DGX-2, it has doubled the on-board memory to 32GB. Nvidia claims the DGX-2 is the world’s first single physical server with enough computing power to deliver two petaflops, a level of performance usually delivered by hundreds of servers networked into clusters.To read this article in full, please click here

Simplifying Linux with … fish?

No, the title for this post is not a mistake. I’m not referring to the gill-bearing aquatic craniate animals that lack limbs with digits or the shark-shaped magnetic Linux emblem that you might have stuck to your car. The “fish” that I’m referring to is a Linux shell and one that’s been around since 2005. Even so, it’s a shell that a lot of Linux users may not be familiar with.The primary reason is that fish isn't generally installed by default. In fact, on some distributions, the repository that provides it is one your system probably doesn't access. If you type "which fish" and your system responds simply with another prompt, you might be missing out on an interesting alternative shell. And, if your apt-get or yum command can't find what you're looking for, you will probably have to use commands like those shown below to get fish loaded onto your system.To read this article in full, please click here

VXLAN Limitations of Data Center Switches

One of my readers found this Culumus Networks article that explains why you can’t have more than a few hundred VXLAN-based VLAN segments on every port of 48-port Trident-2 data center switch.

Expect to see similar limitations in most other chipsets. There’s a huge gap between millions of segments enabled by 24-bit VXLAN Network Identifier and reality of switching silicon. Most switching hardware is also limited to 4K VLANs.
