Precision Time Synchronization & Network Latency

In the second installment of “what’s new” for networking features in Red Hat Enterprise Linux 7, I’d like to shift the focus and spend some time talking about improvements to network time synchronization and enhancements in the network stack designed to reduce latency.  Note that the previous installment of this two part series was posted during the Red Hat Enterprise Linux 7 beta; now that Red Hat Enterprise Linux 7 is generally available I encourage customers to visit the Red Hat Customer Portal, download this latest release, and to let me know what you think.

Highly Accurate Time Synchronization

Precise time synchronization with microsecond or nanosecond accuracy is increasingly critical to the success of many high-speed, low-latency applications. Whether tracking time on trading transactions or market feeds, improving the time stamp accuracy on archived data, or administration-free time synchronization of servers within a rack (or around the world) for automation or regulatory purposes, precision time synchronization is a key enabler for delivering better performance.

New to Red Hat Enterprise Linux 7,

GCC Receives ACM’s 2014 Programming Languages Software Award

At Red Hat, we take pride in the fact that we actively contribute to the projects that are used to build our set of leading enterprise solutions. And when one project’s community is distinguished for their exemplary efforts – we want to recognize them as well.

As such, we are pleased to announce that the GNU Compiler Collection (GCC) has received the Association for Computing Machinery’s (ACM) 2014 Programming Languages Software Award. Awarded to an institution or individuals that have developed a software system with lasting influence, the award recognizes GCC’s 27 years of success and the substantial impact it has had on the software industry, an example of which is its importance to modern datacenter operations.

Not only is GCC a key component of Red Hat Enterprise Linux…

Going Atomic with the Red Hat Enterprise Linux 7 High-Touch Beta

Going atomic with Linux containersNow that Red Hat Enterprise Linux 7 is generally available, we are re-casting the Red Hat Enterprise Linux High Touch Beta program into a series of Red Hat Enterprise Linux 7 special interest groups (SIGs), the first of which is focused on application containers. The Red Hat Enterprise Linux Atomic Host SIG encompasses technologies that are required to create, deploy, and manage application containers.

This is the first of several SIGs that we plan to create to focus on specific technology domains within Red Hat Enterprise Linux 7. By participating in SIGs, Red Hat Enterprise Linux customers can provide feedback on the active development of new capabilities to meet the needs of their specific use cases.

Final Red Hat Enterprise Linux 5 Beta Now Available

When Red Hat Enterprise Linux 5 was first introduced in 2007, it was done so with an expected seven year lifecycle. Five years later, in 2012, we saw the continued strong adoption of Red Hat Enterprise Linux 5 and decided to extend its seven year lifecycle to 10 years. Now, in 2014, the original retirement year for Red Hat Enterprise Linux 5, we still see an active, dedicated customer base that has come to value this long, predictable lifecycle in addition to the platform’s inherent security, stability, and reliability.

Today, we are pleased to announce beta availability of Red Hat Enterprise Linux 5.11. This release continues to provide system administrators with a secure, stable, and reliable platform for their organization’s enterprise applications.

Red Hat Around the Web: Summit Q&A, NetworkManager 0.9.10, and DevOps (Part 3)

Were you able to attend the Red Hat Enterprise Linux roadmap session at this year’s Red Hat Summit?  If not, I have some good news – the slides are still available (here).  In addition, many of the questions that were asked after the presentation were recorded, sorted, and answered… and are now posted on the Red Hat Summit Blog.  Of note:

If You Like Bonding, You Will Love Teaming

In this day and age, where almost everything is connected to the World Wide Web, the demands on networking (in general) are mushrooming. In the developed world it’s common to be able to get 20 megabits per second connections on our mobile devices and 50 megabits per second connections at home. By extension, the demands on enterprise data centers are even higher (by at least three to four orders of magnitude) – as these central “hubs” are where traffic from the aforementioned individual end nodes converge. Consider the act of flipping through a series of cloud-hosted HD photos on a mobile device – this can easily result in billions of packets being transferred (in fractions of a second).

The good news is that our networking interfaces are getting “bigger and faster.” 40 gigabit per second Ethernet is currently being deployed, and work to finalize on 100 gigbit per second end point interfaces is currently underway.

Red Hat Unveils Red Hat Enterprise Linux 7

Six months ago we announced the beta availability of Red Hat Enterprise Linux 7. Two months ago, at Red Hat Summit 2014, we announced the availability of a release candidate for Red Hat Enterprise Linux 7. All the while we have been validating what’s new, different, and exciting about what Red Hat Enterprise Linux 7 has to offer – including:

Today we are pleased to announce the general availability of Red Hat Enterprise Linux 7, the latest major release of our flagship platform. As stated in this morning’s press release:
