Red Hat Enterprise Linux 7 beta file systems: New scale, speed, & features

Red Hat Enterprise Linux 7 beta brings many changes in the file and storage world. Most significant is the choice of XFS as our default file system for all support architectures. This will expand the size of a single file system up to 500TB in supported configurations. The file system stack will also take advantage of support for a wide variety of new storage devices and is tuned to run with better latency and higher speeds on very high speed SSD storage devices. In this session, Ric Wheeler will detail these NFS and GFS2 changes.

Linux containers in Red Hat Enterprise Linux 7 beta

Linux containers is a feature in Red Hat Enterprise Linux 7 beta that provides application deployment flexibility for customers, and allows users to run applications securely in an isolated container. Linux containers facilitate multi-tenancy, density, and deployment speed.

The Linux container technology in Red Hat Enterprise Linux 7 beta combines resource management, process isolation, file system separation, security, and management tooling with Docker to provide robust features to run applications in an isolated container. Docker uses the Linux container capabilities in Red Hat Enterprise Linux 7 beta to provide standardization, ease of use, and portability.

Join this session to learn more about Linux containers and Docker technologies in Red Hat Enterprise Linux 7 beta. The presentation will conclude with a live demonstration.

New networking features & tools for Red Hat Enterprise Linux 7 beta

In today’s world of information overload, networking has become an essential component. Immediate access to information lets organizations make informed business decisions that are critical for success.

In this session, you’ll learn about new networking features and tools found in Red Hat Enterprise Linux 7 beta, as well as areas of future development. We’ll highlight new technologies and protocols, management tools, performance improvements, and more, including updates on:

  •  Network management.
  •  Latency improvement and optimization.
  •  Virtual networking and overlay technology.
  •  Precise-time synchronization.

Demystifying systemd: A practical guide

Red Hat Enterprise Linux 7 beta provides several new capabilities and features, along which comes change. One of the most talked-about changes is the replacement of Upstart with systemd. Fortunately, systemd enables admins and users a host of exciting tools and functionality that simply was not possible in the past. Get ahead of the curve and learn how to get the most out of systemd and Red Hat Enterprise Linux 7 beta. In this session, you’ll learn about basic resource allocation (cgroups) at a service level and how to:

  • Translate init commands and processes to systemd.
  • Convert legacy init scripts.
  • Customize service unit files.
  • Use the journal.

Automatic NUMA balancing for bare-metal workloads & KVM virtualization

Red Hat and its partners, such as HP, have demonstrated world-class virtualization performance with SPECvirt and other benchmarks running on Red Hat Enterprise Linux with Kernel-based Virtual Machine (KVM) technology. In doing so, KVM has proven to be feature rich and highly scalable, and has leading performance, becoming the hypervisor of choice for OpenStack development and enterprise virtualization.

Combining Red Hat Enterprise Linux 7 beta with KVM on the next generation of HP servers, Red Hat and HP engineers will demonstrate the latest results for out-of-the-box performance using automatic NUMA, balancing in the host kernel as well as within Red Hat Enterprise Linux 7 beta guests.

You’ll hear about the latest NUMA enhancements directly from the engineers who are leading the way in NUMA kernel development and testing. See their latest test results on bare metal and with KVM guests, learn how it works, and hear how the Linux kernel design compares to other algorithms.

Interoperability update: Red Hat Enterprise Linux 7 beta & Microsoft Windows

In this session, you’ll get an update on the latest methods available for integrating Red Hat Enterprise Linux servers into Active Directory domain environments. Emphasis will be placed on how the new Red Hat Enterprise Linux 7 beta features can streamline the integration process. Topics covered include:

Integration overview

  • Integration approaches (direct vs. indirect, third-party)
  • Best practices and integration guidelines

Red Hat Enterprise Linux 6: The foundation

  •  Components (Samba, Winbind, IdM, AD DS, Kerberos, LDAP, SSSD)
  •  Configurations and use cases

Red Hat Enterprise Linux 7 beta: Extending the foundation

  •  realmd (new feature)
  •  Cross-realm trusts
  •  Configurations and use cases
  •  Futures (SSSD, non-Samba file sharing)

Whether you are running an existing Red Hat Enterprise Linux environment or deploying a new one, Red Hat Enterprise Linux 7 beta streamlines integration with Windows Active Directory domain environments.

The next-generation firewall for Red Hat Enterprise Linux 7 beta

The Linux packet filtering technology, iptables, has its roots in times when networking was relatively simple and network bandwidth was measured in mere megabits. Emerging technologies, such as distributed NAT, overlay networks and containers require enhanced functionality and additional flexibility. In parallel, the next generation of network cards with speeds of 40Gb and 100Gb will put additional pressure on performance.

In the upcoming Red Hat Enterprise Linux 7, a new dynamic firewall service, FirewallD, is planned to provide greater flexibility over iptables by eliminating service disruptions during rule updates, abstraction, and support for different network trust zones. Additionally, a new virtual machine-based packet filtering technology, nftables, addresses the functionality and flexibility requirements of modern network workloads.

In this session you’ll:

  • Deep dive into the newly introduced packet filtering capabilities of Red Hat Enterprise Linux 7 beta.
  • Learn best practices.
  • See the new set of configuration utilities that allow new optimization possibilities.

Migrating existing Red Hat Enterprise Linux installations to new major versions

Many Red Hat Enterprise Linux 5 and 6 customers will soon consider migrating to Red Hat Enterprise Linux 7. Red Hat now offers tools for engineers to evaluate migration options and plan their upgrades accordingly. In this session, you’ll see those tools in action during a live demo of an upgrade.
