Red Hat Enterprise Linux 6 Coming Soon!

Rumoured to be released from November 1st, Red Hat Enterprise Linux 6 blurs the lines between virtual, physical, and cloud computing to address shifts taking place in the modern IT environment. Featuring updated core technology, from the kernel to the application infrastructure to the development toolchain, Red Hat Enterprise Linux 6 is designed to meet the needs of the coming generations of hardware and software technologies.

As Perth’s only Red Hat Advanced Business Partner, Open Systems is ready to help you move to Red Hat Enterprise Linux 6 to take advantage of the great features.

The Red Hat Enterprise Linux 6 platform has a larger feature set compared to prior releases as is evident by the greater number of packages compared to Red Hat Enterprise Linux 5. The following are some of the many improvements and new features that will be included in Red Hat Enterprise Linux 6 :

Updated kernel and core technology stack: a completely updated core which includes a newer kernel and associated user-space management tools. Also updated are core applications like httpd, Samba and NFS.

Virtualization: fully integrated and based on the KVM hypervisor. A range of new features improve scalability, I/O performance and deployment flexibility. The application environment is consistent across physical and virtual systems and simplifies the adoption of virtualization.

Power management: tickless kernel and improvements through the application stack to reduce wakeups, power consumption measurement by Powertop, Power Management (ASPM, ALPM), and adaptive system tuning by Tuned, all enhance more efficient system power usage.

Next generation networking: comprehensive IPv6 support (NFS 4, CIFS, mobile support [RFC 3775], ISATAP support), FCoE, iSCSI, and a new and improved mac 802.11 wireless stack.

Reliability, availability, and serviceability (RAS): system-level enhancements from industry collaborations make the most of hardware RAS capabilities and NUMA architectures.

Performance: improvements in the kernel and user-space stack allow for better utilization of the infrastructure (processors, NUMA/SMB, networking, storage, file system, etc.) resulting in industry leading performance of applications.

Scalability: Scales to the largest systems on the market today with plenty of expansion capabilities for growth tomorrow. Physical, virtual and cloud deployments are supported.

Fine-grained control and management: improved scheduler and better resource management in the kernel via Completely Fair Scheduler (CFS) and Control Groups (cgroups). The cgroups offer a powerful way to allocate process, memory, and I/O resources between process groups whether they be applications or virtual guests.

Filesystem and storage: ext4 file system provides support for larger file sizes and significantly reduces repair times over ext3. XFS® is a high-performance file system that supports extremely large files and is optimized for large data transfers.

Enterprise security enhancement: SELinux includes improved ease of use, application sandboxing, and significantly increased coverage of system services, while SSSD provides unified access to identity and authentication services as well as caching for off-line use.

Development and runtime support: SystemTap improvements, ABRT is a new framework for simple collection and reporting of bug information, and improvements are made to GCC (version 4.4.3), glibc (version 2.11.1), and GDB (version 7.0.1).
