RedHat 6 Linux torrent version 
(Torrent file for download)





Red Hat Enterprise Linux 6, the latest release of Red Hat's trusted datacenter platform, delivers advances in application performance, scalability, and security. With Red Hat Enterprise Linux 6, you can deploy physical, virtual, and cloud computing within your datacenter, reducing complexity, increasing efficiency, and minimizing administration overhead while leveraging technical skills and operational know-how. Red Hat Enterprise Linux 6 is an ideal platform to translate current and future technology innovations into the best value and scale for IT solutions.

Scalability


  • Red Hat Enterprise Linux 6 supports more sockets, more cores, more threads, and more memory. 

Efficient Scheduling


  • The CFS schedules the next task to be run based on which task has consumed the least time, task prioritization, and other factors. Using hardware awareness and multi-core topologies, the CFS optimizes task performance and power consumption.

Reliability, Availability, and Serviceability (RAS)


  • RAS hardware-based hot add of CPUs and memory is enabled.
  • When supported by machine check hardware, the system can recover from some previously fatal hardware errors with minimal disruption.
  • Memory pages with errors can be declared as "poisoned", and will be avoided.

Filesystems


  • The new default file system, ext4, is faster, more robust, and scales to 16TB.
  • The Scalable File System Add-On contains the XFS file system, which scales to 100TB.
  • The Resilient Storage Add-On includes the high availability, clustered GFS2 file system.
  • NFSv4 is significantly improved over NFSv3, and is backwards compatible.
  • Fuse allows filesystems to run in user space allowing testing and development on newer fused-based filesystems (such as cloud filesystems).

High Availability


  • The web interface based on Conga has been re-designed for added functionality and ease of use.
  • The cluster group communication system, Corosync, is mature, secure, high performance, and light-weight.
  • Nodes can re-enable themselves after failure without administrative intervention using unfencing.
  • Unified logging and debugging simplifies administrative work.
  • Virtualized KVM guests can be run as managed services which enables fail-over, including between physical and virtual hosts.
  • Centralized configuration and management is provided by Conga.
  • A single cluster command can be used to manage system logs from different services, and the logs have a consistent format that is easier to parse.

Power Management


  • The tickless kernel feature keeps systems in the idle state longer, resulting in net power savings.
  • Active State Power Management and Aggressive Link Power Management provide enhanced system control, reducing the power consumption of I/O subsystems. Administrators can actively throttle power levels to reduce consumption.
  • Realtime drive access optimization reduces filesystem metadata write overhead.
