Worth Reading: The shape of HPC and AI iron to come

In the IT business, just like any other business, you have to try to sell what is on the truck, not what is planned to be coming out of the factories in the coming months and years. AMD has put a very good X86 server processor into the market for the first time in nine years, and it also has a matching GPU that gives its OEM and ODM partners a credible alternative for HPC and AI workload to the combination of Intel Xeons and Nvidia Teslas that dominate hybrid computing these days. —Timothy Prickett Morgan @ The Next Platform

PCAP PCAP PCAP – Changes to RJ Store

I made a couple changes to the RouterJockey store this week and I wanted to make sure I got the word out. Previously the store worked in sprints that I tried to open up 2-3x a year. Instead of trying to manage these sprints, and keep the products updated, I’ve now made the store available year round. It still operates in sprints, but instead of being 2-3 weeks long, they’re only 3-4 days each.

On top of being more available, the store now has a few new products, nothing too exciting, but we do have a RJ phone case, a PCAP mug, and a couple stickers for sale. Teespring has recently added these products and as I get requests for other products I will be sure to add them. As usual, if you have any questions, hit me up on twitter or use the contact form.

Click here, or use the store item in the menu bar to visit my new storefront.

Expand Wi-Fi quickly, easily with Aerohive’s wall plate

In many industries, it’s critical to get Wi-Fi everywhere, but it can often be difficult accomplish this. For example, extending a hotel comprised of smaller cottage-type rooms or one with lots of suites has many hard to reach places with traditional access point (AP) placement. Dorm rooms or hospitals typically want Wi-Fi everywhere, but it’s often difficult to provision it because of interference from thick walls or other infrastructure. One possible solution is to put an AP in every room, but that can get prohibitively expensive given the cost of APs and the expense of running new cables to every location.Another option has been the growing number of “wall plate” APs where the existing wall plate is removed and an AP in the form factor of a wall plate is connected into the existing Ethernet cable, bringing Wi-Fi to that location.To read this article in full or to leave a comment, please click here

Where Serverless And Event Driven Computing Collide

Every new paradigm of computing has its own framework, and it is the adoption of that framework that usually makes it consumable for the regular enterprises that don’t have fleets of PhDs on hand to create their own frameworks before a technology is mature.

Serverless computing – something that strikes fear in the hearts of many whose living is dependent on the vast inefficiencies that still lurk in the datacenter – and event-driven computing are two different and often associated technologies where the frameworks are still evolving.

The serverless movement, which we have discussed before in analyzing the Lambda efforts …

An Exascale Timeline for Storage and I/O Systems

The more things change, the more they stay the same.

While exascale supercomputers mark a next step in performance capability, at the broader architectural level, the innovations that go into such machines will be the result of incremental improvements to the same components that have existed on HPC systems for several years.

In large-scale supercomputing, many performance trends have jacked up capability and capacity—but the bottlenecks have not changed since the dawn of computing as we know it. Memory latency and memory bandwidth remain the gating factors to how fast, efficiently, and reliably big sites can run—and there is still …

New digital platforms to become the foundation for IT

The future of business will include artificial intelligence (AI) in every nook and cranny, along with transparent, immersive experiences and entirely new digital platforms, according to consulting firm Gartner.Digital business will be driven by those three megatrends over the next five to 10 years, it says.That's because a kind of joining between humans and technology is going to replace the static-like tech we’re used to. The new combination will be enabled by revolutionary amounts of data, better computing power and ubiquitous ecosystems.+ Also on Network World: Gartner Top 10 technology trends you should know for 2017 + Importantly, to get there, new digital “ecosystem-enabling” platforms will have to replace traditional “compartmentalized technical infrastructure.”To read this article in full or to leave a comment, please click here

Worth Reading: We’re Still on Whois?

Here we are in a modern age, and yet the load on the public whois service at APNIC continues unabated. It’s believed they’re mostly queries from automatic systems, checking the authority over an IP address, almost certainly from firewall checks, an amount of manual data exploration by law enforcement and IPR agencies, and at the tail end, ISPs doing semi-automatic router configuration. —George Michaelson @ APNIC

How to use oVirt Ansible roles

The recent post, An Introduction to Ansible Roles, discussed the new roles that were introduced in the oVirt 4.1.6 release. This follow-up post will explain how to set up and use Ansible roles, using either Ansible Galaxy or oVirt Ansible Roles RPM.

Ansible Galaxy

To make life easier, Ansible Galaxy stores multiple Ansible roles, including oVirt Ansible roles. To install the roles, perform the next steps:

To install roles on your local machine, run the following command:

$ ansible-galaxy install ovirt.ovirt-ansible-roles

This will install your roles into directory /etc/ansible/roles/ovirt.ovirt-ansible-roles/.

By default, Ansible only searches for roles in /etc/ansible/roles/ directory and your current working directory.

To change the directories where Ansible looks for roles, modify the roles_path option of [defaults] section in ansible.cfg configuration file.

The default location of this file is in /etc/ansible/ansible.cfg.

$ sed -i 's|#roles_path    = /etc/ansible/roles|roles_path = /etc/ansible/roles:/etc/ansible/roles/ovirt.ovirt-ansible-roles/roles|'  /etc/ansible/ansible.cfg

For more information on changing the directories where Ansible searches for roles, see the Ansible documentation pages.

Copy one of the examples from the directory /etc/ansible/roles/ovirt.ovirt-ansible-roles/examples/ into your working directory, then modify the needed variables and run the playbook.

oVirt Ansible Roles RPM

History Of Networking – Daniel Walton – BGP Optimizations

In the late 1990s and early 2000s, BGP had some serious scaling issues that threatened it’s effectiveness as a protocol that could be used for the global routing table.  Significant efforts were made to optimize the resource utilization and convergence time.  Our guest in this episode, Daniel Walton, was part of that effort at Cisco and shares his story about the BGP optimizations that were put in place during that time.  The optimizations include Peer groups, READONLY mode, update groups, update packing, and MRAI.  Sometimes these optimizations, increased capability by 100x previous versions of the code.
