Following is a snapshot of Enterprise Linux : –> What is it? Red Hat Enterprise Linux is the premier operating system for open source computing. It’s sold by annual subscription, runs on seven system architectures, and is certified by top enterprise software and hardware vendors. It’s backed by a Red Hat Network subscription up to 24×7 support with one-hour response, and the Red Hat Open Source Assurance program. –>What does it do? Red Hat Enterprise Linux creates a reliable, secure, high performance platform designed for today’s commercial environments–with capabilities that match or surpass those of proprietary operating systems. Sold in three products that span client systems to the largest servers, Red Hat Enterprise Linux delivers a consistent application, management, and user environment. –>Why should I care? Red Hat Enterprise Linux is the corporate Linux standard. It’s already at work running some of the world’s largest commercial, government, and academic institutions. For any deployment–from the desktop to the datacenter-Red Hat Enterprise Linux delivers unmatched performance and cost savings, and the freedom of open source technology. –>Red Hat Enterprise Linux Features and Benefits All products in the Red Hat Enterprise Linux family are based on a common software core–kernel, libraries, development toolchain, and utilities. This provides a homogeneous environment ideal for simplifying multi-system and desktop-to-datacenter configurations. The immediate benefit: simplified deployment of distributed applications, and a consistent environment for users and system administrators across the entire family. –>New in Red Hat Enterprise Linux, Version 3 Introduced in September 2003, Red Hat Enterprise Linux, version 3, includes a broad range of new features: 1) Support for seven architectures: Intel X86, Intel Itanium, AMD AMD64 and IBM zSeries, iSeries, pSeries, and S/390. 2) 4-4 memory split: Increased kernel & user address space for X86 systems, allowing support for 64GB of main memory and larger user applications. 3) Native Posix Thread Library: A new high-performance multi-threading capability provides improved performance for multi-threaded applications. 4) Based on Linux 2.4.21 kernel: Red Hat Enterprise Linux uses the latest stable Linux kernel with numerous additions from the Linux 2.5/2.6 kernels. 5) Improved scalability: Support for larger SMP, memory and I/O systems allows version 3 to support servers approximately twice the size of version 2.1. 6) Forward compatibility: Version 3 includes compatibility libraries so it can run version 2.1 applications without modification. 7) Standards support: LSB 1.3 compliant and undergoing NIAP CC EAL2 evaluation. 8) Improved desktop: Includes Red Hat’s Bluecurve graphical user interface, and a comprehensive set of personal productivity applications. 9) Enhanced security: Includes several new security features, including support for file system ACLs. 10) Bundled Stronghold: Red Hat’s secure web server solution, previously available as a separate layered product for Enterprise Linux AS, has been updated to Apache version 2 and included as part of the base Red Hat Enterprise Linux product set. 11) Improved compiler/tools: Includes GCC 3.2 and debugging/profiling tools. 12) Logical Volume Manager: Provides enterprise-strength storage management. 13) Diskless systems: Supports deployment of diskless clients. 14) Enhanced Java: Java implementations from BEA and IBM. 15) Enhanced networking: Includes numerous features to improve stability & performance. 16) Support for Samba 3 provides numerous new features: Greatly improved interoperability with Microsoft Active Directory. Samba 3.0 is able to join an ADS realm as a member server and authenticate users using LDAP/Kerberos Improved Windows 2000/XP/2003 printing support including publishing printer attributes in active directory Support for migrating from a Windows NT 4.0 domain to a Samba domain and maintaining user, group and domain SIDs Support for establishing trust relationships with Windows NT 4.0 domain controllers Support for client and server SMB signing to ensure compatibility with default Windows 2003 security settings Improved ACL mapping –>For more information on these and other new features, please refer to the Red Hat Enterprise Linux Feature-Function-Benefit analysis.
