Red Hat announced Wednesday the availability of Red Hat Enterprise Linux 5.2, with improvements in virtualization, clustering, and hardware support.

Version 5.2 was described as a minor update Red Hat Daniel Riek, product marketing manager for Red Hat Enterprise Linux.

“We do these twice yearly updates,” said Riek.

With the release, the virtualization of very large systems, since up to 64 CPUs and 512GB memory is possible. Support for NUM architectures have been used, as well as improvements in security, performance and management, Red Hat said.

CPU frequency is offered for virtualized environments and to reduce? energy consumption. Also, increased capabilities are presented for hardware architectures, such as X/86/x86-64 Intel, Itanium, and Power and IBM System z. These capabilities provide for improved performance, energy use, expansion, and manageability, Red Hat said.

Support for Dynamic Intel Technology Acceleration permit energy-saving “quiescing” core CPU idle, Red Hat said. With quiescing, a team that is put into an inactive state to conserve power, but may be reactivated quickly because it is still available and has not been completely shut down.

In addition, it improves performance of “overclocking” cores occupied within safety levels heat. Other improvements include upgrades of hardware device drivers and certification systems IBM Cell Blade.

A more intelligent script pushes the installation of the grouping in version 5.2, Riek said. “The ability to speak with the applications being grouped, has been improved,” he said.

Red Hat Enterprise Linux Desktop 5.2, meanwhile, includes increased support for portable suspend / hibernate and resume, updated graphics controller, and an upgrade of desktop applications including OpenOffice 2.3 and Firefox v3.
