I published the last part of my Optimize Data Center Infrastructure series: build an optimized data center fabric.
To learn more about data center fabric designs, check the new online course or enroll into the Spring 2018 session of Building Next-Generation Data Center course.

This interoperability test sets the stage for 5G NR operator trials next year.
The market for high performance computing can be a capricious one in any short term, but in general has been growing and, at last according to some of the experts who have spent decades tracking it, is set to grow a little bit faster than the IT sector at large in the coming years.
A lot, of course, will depend on whether or not the United States, Europe, China, and Japan come through with what are expected to be substantial investments in pre-exascale and exascale systems in the next few years, and quite possibly resulting in a bumper crop of …

Each string will be written as a line in a file stored under /etc/cumulus/acl/policy.d/ - See Cumulus Linux: Netfilter - ACLs. For example, the rule above will be written to the file 50rest-ddos1.rules with the following Continue reading
The platform originally was part of its Terragraph wireless backhaul network.
Remote user authentication and role based access control (RBAC) is an important requirement when deploying new systems in an organization, particularly in the networking world. For that matter, systems typically leverage RADIUS or Active Directory (AD) servers, to name a few.
NSX-T integrates with VMware Identity Manager (vIDM) to get the following benefits related to user authentication:
This blog post covers the main steps required to integrate NSX-T with vIDM and to configure roles that grant different privileges to different users. It does not cover deployment and hardening of VMware Identity Manager (vIDM). At the end of the post, there is a link to a demo showing how to do the configuration and several role-based access tests.
Assuming that both NSX-T Manager and vIDM appliances are deployed, powered on and configured with the basic management details (IP address, admin users, etc.), the integration requires the following steps:
But the company cautions that 5G is about more than a fast connection.
Oracle claims the upgrades best AWS with 1,214 percent better storage performance.
Cablecos, tower firms, or municipalities can get a cut of the IoT revenues.
At DockerCon Europe, we announced that the next release of Docker Enterprise Edition (Docker EE) would include Kubernetes integration. We’re really excited about bringing Kubernetes to our customer base and continuing to increase our involvement within the community. But it’s equally important for us to note that Swarm orchestration is not going away. Swarm forms an integral cluster management component of the Docker EE platform; in addition, Swarm will operate side-by-side with Kubernetes in a Docker EE cluster, allowing customers to select, based on their needs, the most suitable orchestration tool at application deployment time.
Here are just a few reasons that Swarm is integral to the Docker EE solution:
Docker now has hundreds of Docker EE customers who have standardized on Swarm orchestration. In fact, at our Customer Summit during DockerCon, all of the customers stated that they intend to continue using Swarm even with the Kubernetes announcement. Having both orchestration options available is definitely a plus for some of these customers that have organizations within the company using both Swarm and Continue reading
It was 31 years ago when Alan Karp, then an IBM employee, decided to put up $100 of his own money in hopes of solving a vexing issue for him and others in the computing field. When looking at the HPC space, there were supercomputers armed with eight powerful processors and designed to run the biggest applications of the day. However, there also were people putting 1,000 wimpy chips into machines that leveraged parallelism to run workloads, a rarity at the time.
According to Amdahl’s Law in 1986, even if 95 percent of a workload runs in parallel, the speedup …
Gordon Bell Looks Out Into A Parallel World was written by Jeffrey Burt at The Next Platform.
No doubt, there’s a plethora of information on the web about SD-WAN, short for Software-Defined Wide Area Network. It’s the next big thing in networking and everyone’s writing, making a video, or talking about it. But, if you’re like me, any time a new technology emerges, I prefer to learn the fundamentals before jumping into... Read more →
