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.

IDG Contributor Network: 8 steps to IT control in a self-service cloud world

The natural cycle in IT is to move from decentralized to centralized services. When networking first appeared, it was implemented at a department level for printer sharing. It was decentralized—resulting in a hodgepodge of networks and protocols. Eventually IT organizations determined that it was much more efficient to centralize this effort and we saw the adoption of large-scale, TCP/IP networks. Today nearly every IT organization has a centralized networking team that manages and deploys IP-based infrastructure.When SaaS applications such as Salesforce first appeared, they were adopted by sales organizations. As adoption levels grew, enterprises needed centralized data integration, identity and access management, and other functions that are inefficient to deliver at departmental scale. Today Salesforce is typically managed by a centralized IT organization.To read this article in full or to leave a comment, please click here

IDG Contributor Network: How to see the world more clearly through interconnection

Interconnection is the fuel of digital business, and organizations must understand its power if they hope to handle the global digital economy’s increasing demands. For such a pivotal business enabler, interconnection has long been tough to quantify. But new research from the company I work for, Equinix, does just that by looking at installed interconnection bandwidth capacity and projected growth. The Global Interconnection Index, published by Equinix and sourced from multiple analyst reports, is an industry-first look at how interconnection bandwidth is shaping and scaling the digital world. It aims to give digital business the insight needed to prepare for tomorrow. To read this article in full or to leave a comment, please click here
