Features of RedHat Linux 6 !!
1) 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.
2) 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.
3) 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.
4) 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.
5) 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
6) 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.
