Today, the DPDK community announced during the Open Networking Summit that they are moving the project to the Linux Foundation, and creating a new governance structure to enable companies to engage with the project, and pool resources to promote the DPDK community. As a long-time contributor to DPDK, Red Hat is proud to be a founding Gold member of the new DPDK Project initiative under the Linux Foundation.

As the OpenStack market continues to mature, some organizations have made the move and put OpenStack projects into production. They have done this in a variety of ways for a variety of reasons. However, other organizations have waited to see what these first-movers are doing with it and whether or not they are successful before exploring for themselves.
As such, we’re pleased to announce the availability of 4 new analyst white papers from 451 Research on how organizations are using OpenStack in production. The information in these papers is based on 451 Research’s own insights as well as interviews with customers who have put OpenStack into production.

In OpenStack jargon, an Instance is a Virtual Machine, the guest workload. It boots from an operating system image, and it is configured with a certain amount of CPU, RAM and disk space, amongst other parameters such as networking or security settings.
In this blog post kindly contributed by Marko Myllynen we’ll explore nine configuration and optimization options that will help you achieve the required performance, reliability and security that you need for your workloads.
Some of the optimizations can be done inside a guest regardless of what has the OpenStack Cloud Administrator enabled in your cloud. However, more advanced options require prior enablement and, possibly, special host capabilities. This means many of the options described here will depend on how the Administrator configured the cloud, or may not be available for some tenants as they are reserved for certain groups. More information about this subject can be found on the Red Hat Documentation Portal and its comprehensive guide on OpenStack Image Service. Similarly, the upstream OpenStack documentation has some extra guidelines available.
The following configurations should be evaluated for any VM running on any OpenStack environment. These changes have no side-effects and are typically safe to enable even if unused

With software-defined networking (SDN) and network functions virtualization (NFV) gaining traction, more cloud service providers are looking for open solutions, based on standardized hardware platforms and open source software. In particular, communication service providers (CSPs) are undergoing a major shift from specialized hardware-based network elements to a software based provisioning paradigm where virtualized network functions (VNFs) are deployed in private or hybrid clouds of network operators. Increasingly, OpenStack is seen as the virtual infrastructure platform of choice for NFV, with many of the world’s largest communications companies implementing solutions with OpenStack today.

The OpenStack Kilo release, extending upon efforts that commenced during the Juno cycle, includes a number of key enhancements aimed at improving guest performance. These enhancements allow OpenStack Compute (Nova) to have greater knowledge of compute host layout and as a result make smarter scheduling and placement decisions when launching instances. Administrators wishing to take advantage of these features can now create customized performance flavors to target specialized workloads including Network Function Virtualization (NFV) and High Performance Computing (HPC).
What is NUMA topology?
Historically, all memory on x86 systems was equally accessible to all CPUs in the system. This resulted in memory access times that were the same regardless of which CPU in the system was performing the operation and was referred to as Uniform Memory Access (UMA).
In modern multi-socket x86 systems system memory is divided into zones (called cells or nodes) and associated with particular CPUs. This type of division has been key to the increasing performance of modern systems as focus has shifted from increasing clock speeds to adding more CPU sockets, cores, and – where available – threads. An interconnect bus provides connections between nodes, so that all CPUs can still access all memory. While the memory bandwidth of the interconnect is typically faster than that of an individual node it can still be overwhelmed by concurrent cross node traffic from many nodes. The end result is that while NUMA facilitates faster memory access for CPUs local to the memory being accessed, memory access for remote CPUs is slower.

Red Hat Enterprise Linux OpenStack Platform 6: SR-IOV Networking – Part I: Understanding the Basics
Red Hat Enterprise Linux OpenStack Platform 6 introduces support for single root I/O virtualization (SR-IOV) networking. This is done through a new SR-IOV mechanism driver for the OpenStack Networking (Neutron) Modular Layer 2 (ML2) plugin, as well as necessary enhancements for PCI support in the Compute service (Nova).
In this blog post I would like to provide an overview of SR-IOV, and highlight why SR-IOV networking is an important addition to RHEL OpenStack Platform 6. We will also follow up with a second blog post going into the configuration details, describing the current implementation, and discussing some of the current known limitations and expected enhancements going forward.

On Tuesday February 17th, we announced the general availability of Red Hat Enterprise Linux OpenStack Platform 6, Red Hat’s fourth release of the commercial OpenStack offering to the market.
Based on the community OpenStack “Juno” release and co-engineered with Red Hat Enterprise Linux 7, the enterprise-hardened Version 6 is aimed at accelerating the adoption of OpenSack among enterprise businesses, telecommunications companies, Internet service providers (ISPs), and public cloud hosting providers.
Since the first version released in July 2013, the “design principles” of Red Hat Enterprise Linux OpenStack Platform product offering are:

The energy from the latest OpenStack Summit in Paris is still in the air. Its record attendance and vibrant interactions are a testimony of the maturity and adoption of OpenStack across continents, verticals and use cases.
It’s especially exciting to see its applications growing outside of core datacenter use cases with Network Function Virtualization being top of mind for many customers present at the Summit.
If we look back at the last few years, a fundamental role fueling OpenStack adoption has been played by the distributions which have taken the project OpenStack and helped turn it into an easy to consume, supported, enterprise-grade product.
At PLUMgrid we have witnessed this transformation summit after summit, customer deployment after customer deployment. Working closely with our customers and our OpenStack partners we can attest how much easier, smoother, simpler an OpenStack deployment is today.
Similarly, PLUMgrid wants to simplify and accelerate the deployment of OpenStack network infrastructure, especially for those customers that are going into production today and building large-scale environments.
If you had the pleasure to be at the summit you have learnt about all the new features that were introduced in Juno for the OpenStack networking component (and if not check out this blog which provides a good summary of all Juno’s networking feature).

This post is the collective work of all the Red Hat Enterprise Linux OpenStack Platform Product Managers who attended the summit.
The 11th Openstack design summit that took place last week for the first time in Europe, brought about 6000 participants of the OpenStack community to Paris to kick off the design for the “Kilo” release.
If 2014 was the year of the “Superuser”, then clearly the year 2015 seems to be about the “Year of the Enterprise“. The big question is: are we ready for enterprise mass adoption?
More than year ago, at the Openstack Havana design summit, it was clear that although interest in deploying OpenStack was growing, most enterprises were still holding back, mainly due to the lack of maturity of the project. This OpenStack summit, the new cool kid in the Open Cloud infrastructure playground is finally starting to show real maturity signs.
An important indicator for this is the increased number of deployments. The Kilo summit showcased about 16 different large organizations using production workloads on OpenStack, including companies such as BBVA Bank, SAP SE (formerly SAP AG) & BMW.
