Red Hat Enterprise Linux 5.7 Released in Beta

Today, we are pleased to announce the availability of the beta version of the seventh update for Red Hat Enterprise Linux 5.  This beta of Red Hat Enterprise Linux 5.7 contains a number of enhancements for enterprise management, virtualization performance and datacenter flexibility.  Also included are updates to the drivers and kernel to support Intel, AMD, POWER and IBM Mainframe hardware updates.



Red Hat Enterprise Linux 5.7 isn’t simply about supporting new technology.  Proven methodology and lifecycle for backports are just as important.  All new capabilities in Red Hat Enterprise Linux were developed in the open source community and on the latest upstream kernels.  With both Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 5 in the Production Phase 1 of their lifecycle, the features are first supported on Red Hat Enterprise Linux 6 and then selectively backported to Red Hat Enterprise Linux 5.  Today’s beta release significantly enhances the value of standardizing on Red Hat Enterprise Linux by adding new features specifically for the enterprise, such as security profile auditing and flexibility in enterprise directory integration.



In the four years since the introduction of Red Hat Enterprise Linux version 5, our customers’ systems have grown incredibly.  And, the variety of workloads they are running has increased dramatically. Many customers have tens of thousands of servers running everything from networking to inventory management, from desktops to custom risk analysis, the importance of enterprise management  continues to increase.
