ESX Server 2 for production environments.The VMware ESX Server VMware ESX Server is an enterprise-level virtualization product offered by VMware, Inc., a division of EMC Corporation. ESX Server is a component of VMware's larger offering, Virtual Infrastructure, which adds management and reliability services to the core server product. 2, is the latest release of this enterprise-class virtual machine software designed for the most demanding production environments. ESX See VMware. Server works by carving multi-processor servers into smaller servers or virtual machines, allowing multiple operating systems, including Microsoft Windows and Linux, to run simultaneously and independently on the same Intel-based server or blade. With VMware Virtual SMP (Symmetric MultiProcessing) A multiprocessing architecture in which multiple CPUs, residing in one cabinet, share the same memory. SMP systems provide scalability. As business increases, additional CPUs can be added to absorb the increased transaction volume. , a single virtual machine can now span two processors, making it possible for enterprises to deploy all of their mission-critical applications in flexible, secure and portable virtual machines. With Control Center, enterprises can centrally manage and control all of their virtual machines and maximise utilisation of their entire server farm. ESX Server runs directly on the hardware and provides fine-grained resource controls that adapt to the needs of mission-critical applications. The resource management capabilities of ESX Server make it possible to control the levels and limits of CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. , networking, memory and disk I/O allocated to and used by each virtual machine. New and enhanced features in ESX Server 2 include: Scalability * Support for VMware Virtual SMP--Lets up to two processors work together to share the workload of resource- intensive applications and tasks running in a virtual machine * Increased Virtual Machine Support--Supports 80 active virtual machines or 40 virtual machines with Virtual SMP * NUMA (Non-Uniform Memory Access) A multiprocessing architecture in which memory is separated into close and distant banks. NUMA is similar to SMP, in which multiple CPUs share a single memory. However, in SMP, all CPUs access a common memory at the same speed. Support--Enhances performance by automatically optimising memory locality for the best possible utilisation of CPUs in NUMA environments Platform Support * Support for Blade Servers--HP ProLiant BL20p and IBM BladeCenter * Range of Operating Systems includes--Microsoft Windows Server 2003 (Standard, Enterprise, Web), Microsoft Windows 2000 Server (Standard, Advanced), Microsoft Windows XP Professional, Microsoft Windows NT 4, RedHat Advanced Server 2.1, RedHat 7.3, 8.0, 9.0, SuSE Linux Enterprise Server SUSE Linux Enterprise Server (SLES) is a Linux distribution supplied by Novell, targeted at the business market. It is targeted for servers, but can be installed on Desktop computers for testing as well. New versions are released at an interval of 18-24 months. (SLES (SuSE Linux Enterprise Server) See SuSE Linux. ) 8 and SUSE Linux 8.2 * SAN Path Failover--Enhanced reliability with built-in failover support www.vmware.com |
