Leading open source application platform

On one certified platform, Red Hat Enterprise Linux offers your choice of:

  • Applications - Thousands of certified ISV applications
  • Deployment - Including standalone or virtual servers, cloud computing, or software appliances
  • Hardware - Wide range of platforms from the world's leading hardware vendors

This gives IT departments unprecedented levels of operational flexibility. And it gives ISVs unprecedented market reach when delivering applications. Certify once, deploy anywhere. All while providing world-class performance, security, and stability. And unbeatable value.

Kernel

Red Hat Enterprise Linux 5 is based on the Linux 2.6.18 kernel and includes many enhancements over prior releases. These include:

  • Per queue, switchable on-the-fly I/O schedulers
  • High performance pipe implementation
  • IPv4/IPv6 performance enhancements
  • Support for shared cache and multi-core systems
  • Kernel SMP locking enhancements for improved scalability and performance

Benefits:

Improved performance and scalability across the board - memory, CPUs, I/O, networking.

Security

Security Enhanced Linux (SELinux) provides support for MLS (Multi Level Security) policies.

Red Hat Enterprise Linux 5 services are provided with targeted policies enabled by default.

Significant ease-of-use enhancements are provided with the inclusion of the SELinux Troubleshooter, a GUI-based analyzer which guides system administrators on appropriate actions to take in the event of a security alert.

The distribution is built using the fortify-source compiler flag which provides more stringent run-time buffer bounds checking, thereby adding to overall system security.

Benefits:

Red Hat Enterprise Linux offers the highest level of out-of-the-box security in the industry. Security administration is greatly simplified

Auditing
Tracks activities and modifications to the entire system, including file system operations, process system calls, user actions such as password changes, account additions/deletions/modification, use of authentication services, and configuration changes (such as time changes). Provides powerful searching and reporting tools and a unique real-time interface that permits applications to analyze and react to events as they occur.

Benefits:

Auditing allows Red Hat Enterprise Linux 5 to meet US Government certifications such as CAPP/LSPP and NISPOM and also assist organizations to meet regulatory requirements such as Sarbanes, Oxley, and HIPPA.

File systems and storage (virtualization)


To simplify system growth and virtualization adoption, Red Hat Enterprise Linux 5 includes single system/guest versions of three distributed system technologies:

  • Logical Volume Manager (LVM): for creating and managing pools of virtual storage devices
  • Global File System (GFS): a high performance, scalable, POSIX compliant file system. GFS provides support for file systems with up to 8EB theoretical capacity.
  • Distributed Lock Manager (DLM): a sophisticated application synchronization interface.

Single systems or virtualized guests using these technologies can be easily upgraded to operate in multi-system and multi-guest configurations by upgrading to Red Hat Enterprise Linux Advanced Platform, which provides multi-system and multi-guest (cluster-wide) versions of the LVM, GFS and DLM. This seamless migration eliminates the need to remap the storage subsystem, reformat disk partitions, or rewrite application synchronization routines when moving from a standalone server to a multi-system or virtualized configuration.

Benefits:

Upgrade from small and non-virtualized systems to larger configurations while maintaining a consistent file system and logical volume configuration.

UNIX interoperability

New AutoFS and NFSv4 capabilities for UNIX interoperability include:

  • Direct Map Support - providing compatibility with UNIX environments.
  • Lazy-mount and unmount - greatly reduces the number of simultaneous mounts on client systems, thereby allowing efficient deployment in large NFS infrastructures.
  • Maps can be shared with Sun Solaris, HP/UX, IBM AIX, and other UNIX systems.
  • Authenticated binds with LDAP servers using Kerberos, Digest-MD5, etc.
  • Significant NFSv4 enhancements in performance, stability and, with SecureNFS, security, and server-side delegation.
Benefits:

Secure and high performance interoperability with UNIX environments.

Microsoft Windows interoperability

Samba provides interoperability with Microsoft Windows file and print (CIFS) systems. New features include improved integration with Microsoft Active Directory ® with, for example, more consistent user and group mapping, and better support for nested groups. Extensive development work and numerous enhancements have improved the quality and stability of the entire subsystem.

Benefits:

Robust and highly compatible integration with Microsoft Windows file/print and authentication environments

Manageability

Red Hat Network up2date has been replaced with the industry standard Yum updater and Pup graphical interface. A Yum plug-in provides access to Red Hat Network content channels.

Benefits:

Improved, industry standard software installer and updater. Ability to directly access public software repositories.
