RHEL 5.10 Has Finally Arrived

Red Hat (News - Alert) Enterprise Linux 5 came out in 2007. RHEL 5 point releases come out regularly as part of Red Hat’s ten year supported life span. RHEL 5.9 came out in January of 2013. Its latest production release is version 5.10 debuted in October of 2013.

Improvements in RHEL 

5.10RHEL 5.10 contains an updated open source Open Security Content Automation Protocol framework. RHEL 5.10 uses OpenSCAP 0.9.8 and supports the SCAP 1.2 standard. Red Hat Enterprise Linux 5.10 includes Red Hat Access, a diagnostic reporting tool which delivers information through the Red Hat Customer Portal and its attendant knowledge base. Red Hat says that RHEL 5 is in Production Phase 2, focusing on security issues and critical bug fixes. However, they will not be adding new functionality to RHEL 5. Any new functions will be added to the RHEL version 6 product line. RHEL 6 was officially released in 2010 but is still in beta testing.

Satellite Version 5.6

Red Hat simultaneously released Satellite 5.6, the latest version of its server management software. Red Hat Satellite 5.6 enables zero downtime features like hot backups. The latest version of Satellite has improved scaling, better configuration management and system monitoring. Satellite works with both RHEL versions 5 and 6.

Migrating from RHEL 5 to Version 6

RHEL 6 adds non-uniform memory access awareness and greater scalability to up to 4,000 processors. RHEL 6 reportedly can handle sixteen terabytes of memory, greater than any other server system is able to handle. RHEL 6 offers control groups for fine grain resource control with the ability to set policy based controls for CPU, memory and networking resources given to each process in addition to each tenant on a cloud. As a result, RHEL 6 uses about 20% less power than version 5.

Red Hat will help companies migrate from Red Hat Enterprise Linux version 5 to version 6. The interoperability of tools like MySQL and Satellite give consumers time to migrate instead of being forced to upgrade mission critical systems. Red Hat Enterprise Linux 5.10 is a stable, mature application. It supports consumers today, but they need to start planning ahead for the migration to RHEL 6.
