Red Hat Offers Virtualization Performance and Next-Generation Java and Processor Support Capabilities

Updated features deliver enhanced virtualization scalability, OpenJDK functionality and Intel Nehalem processor support

Red Hat, a provider of open source solutions, is rolling out global availability to its Red Hat Enterprise Linux 5.3, featuring open source, commercial-strength technology innovations. In the third update to Red Hat Enterprise Linux 5, customers will receive a wide range of enhancements, including significantly increased virtualization scalability, expanded hardware platform support and incorporation of OpenJDK Java technologies. Customers with a Red Hat Enterprise Linux subscription will receive the Red Hat Enterprise Linux 5.3 update, which is available for immediate download from Red Hat Network.

The primary new features of Red Hat Enterprise Linux 5.3 include increased scalability of virtualized x86-64 environments. This includes the ability to support virtual servers with up to 32 virtual CPUs and 80GB of memory. Physical server limits have also been expanded to match the size of today's latest hardware systems, with up to 126 CPUs and 1TB main memory. New features, such as support for Hugepage memory and Intel Extended Page Tables (EPT), dramatically improve the performance of virtual servers. For customers, these enhancements allow more and larger virtual systems to be configured on powerful servers, thereby reducing costs. Additionally, more devices can be allocated to each virtual server (guest), enabling the virtualization of applications with heavy I/O requirements.
