User manual REDHAT ENTERPRISE LINUX DATASHEET

[. . . ] Key partnerships across the industry allow Red Hat to test for the stability of their hardware, software, and management interfaces. Support for the latest hardware is included with service packs and is delivered through minor releases. Applications do not need to be re-built or re-certified with each release update because the application programming and binary interfaces (API/ABI) are held stable for the full life of a Red Hat Enterprise Linux release, regardless of the physical or virtual deployment model. This means that Red Hat's rich ecosystem of thousands of applications are immediately available, avoiding delays that would otherwise occur with expensive and time-consuming re-testing efforts. [. . . ] Red Hat Enterprise Linux, in cooperation with Red Hat's hardware partners, is enabling RAS (reliability, availability, security) and scalability features that have been recently introduced to mainstream architectures. Operational cost savings and physical space considerations drive the need for these higher-efficiency systems. For example, a 64-CPU www. redhat. com system with 1 Terabyte of memory, which previously may have consumed a full rack, can now be configured in a single 4U form factor, and can deliver improved performance at a much lower cost. Red Hat Enterprise Linux also includes low-level kernel optimizations aimed at providing full application performance while in the lowest possible power states. Red Hat Enterprise Linux continues to regularly set new standards in the industry on workload benchmarks as diverse as ERP, Business Intelligence, TPC, and SPEC. See why Red Hat solutions are preferred for getting the most out of hardware and applications. Red Hat is a driving force behind the development of open source virtualization technology. Red Hat's approach to virtualization is easy to adopt, because it is delivered as an integral part of the Red Hat Enterprise Linux platform. The original release of Red Hat Enterprise Linux 5 in early 2007 incorporated an enterprise-hardened implementation of the Xen-based hypervisor technology. With Red Hat Enterprise Linux 5. 4, Red Hat also introduced the newest virtualization technology, Kernel-based Virtual Machine (KVM), which is integrated into the Linux kernel and leverages the newest hardware virtualization capabilities provided by Intel and AMD processor platforms. The modular design of Red Hat Enterprise Linux allows customers to choose when and where to use virtualization within the context of their deployment. For additional flexibility, customers can deploy both Red Hat Enterprise Linux and Microsoft® Windows® as fully supported guests. Red Hat Enterprise Linux supports multiple virtualization use cases, from hardware abstraction for existing software stacks, to datacenter consolidation, to virtualized clusters and private clouds. Security for Red Hat Enterprise Linux begins with a core feature known as Security-Enhanced Linux (SELinux). Government's National Security Agency, SELinux provides for a strong and flexible MAC framework to enforce role-based access control and multi-level security. In addition to SELinux, Red Hat Enterprise Linux includes system firewalls, audit capabilities, and system package and file integrity verification tools for a complete security architecture that covers deployment models ranging from Internet-facing servers to trusted computers. Backing up the core technology is the Red Hat Security Response Team, recognized as industry leaders for addressing security vulnerabilities. In summary, Red Hat Enterprise Linux provides an unmatched security environment for customers and their applications. An integrated high-availability clustering capability allows customers to easily deploy and manage high-availability applications. Scaling from two to 16 nodes, application high availability can be managed through policy definitions.
