Red Hat, Inc. this week announced the general availability of Red Hat Enterprise Linux 5.3 (RHEL 5.3).
"On the hardware front, RHEL 5.3 supports Intel's new Nehalem chip architecture," writes InternetNews' Sean Michael Kerner. "Nehalem has a different memory layout than previous generations of Intel CPU architectures and thus required different memory management configuration on the RHEL side to optimize performance. RHEL 5.3 also provides a boost for virtualization with support for up to 1 TB of memory per virtualization host as well as being able to handle up to 126 CPUs."
"Virtualization in RHEL 5.3 has been improved, including the ability to make larger virtualized machines -supporting up to 32 virtual CPUs and 80GB of RAM – in x86-64 environments," writes ZDNet's Alex Serpo. "RHEL is currently used to run a number of large virtualization instances, including Amazon's elastic computing cloud, known as EC2."
"RHEL 5.3 for the first time implements OpenJDK, an open source 'high-performance' version of Java SE 6… Based on the same code base as Sun's JDK, RHEL's OpenJDK implementation is compatible with all applications written for Java SE 6 and previous versions," writes Linux-Watch's Eric Brown.
