The tried-and-true Red Hat Enterprise Linux (RHEL) open-source enterprise platform recently was upgraded to version 6.4. The new release, which continues in RHEL's tradition of delivering technology that is tested and stable, includes updates to the platform's existing feature set and provides new functionality in the areas of identity management, filesystem, virtualization, storage and productivity tools. Identity management is improved via SSSD enhancements that strengthen the interoperability experience with Microsoft Active Directory. Filesystem enhancements from pNFS deliver performance improvements with the addition of Direct I/O for faster data access. Virtualization is more robust, thanks to the inclusion of the Microsoft Hyper-V Linux drivers and other improvements. Storage management is now easier thanks to new system log features that simplify the process of locating specific devices. Productivity-tool upgrades include interoperability improvements with Microsoft Exchange, calendar support in Evolution and support for newer Wacom tablets.
