NEW LINUX NETWORX EVOLOCITY 1240S CLUSTER SERVER MAXIMIZES SYSTEM UPTIME FOR INTERNET SERVERS; CLUSTER TECHNOLOGY REPRESENTS PARADIGM SHIFT IN WEB SERVING.Linux NetworX introduces Evolocity 1240s, designed for managing and optimizing Web traffic in the Internet market. By placing all Web services (1) Loosely, any online service delivered over the Web. Such usage appears in articles from non-technical sources, but not in IT-oriented publications, because definition #2 below describes the correct use of the term. on Evolocity 1240s, Internet service providers Internet service provider (ISP) Company that provides Internet connections and services to individuals and organizations. For a monthly fee, ISPs provide computer users with a connection to their site (see data transmission), as well as a log-in name and password. (ISPs) and application service providers (ASPs) can achieve maximum system uptime by taking advantage of the redundancy, failover and scalability clustered server technology offers. Cluster technology, on which Evolocity 1240s is based, is a method of linking multiple computers, or compute modules, together to form a powerful, unified system. The server contains all of the tools needed for high availability Also called "RAS" (reliability, availability, serviceability) or "fault resilient," it refers to a multiprocessing system that can quickly recover from a failure. There may be a minute or two of downtime while one system switches over to another, but processing will continue. Web serving. Linux NetworX will unveil the Evolocity 1240s at the Networld+Interop 2000 trade show Sept. 26. To limit service downtime, ISPs often have many different machines dedicated for single services. For example, an ISP (1) See in-system programmable. (2) (Internet Service Provider) An organization that provides access to the Internet. Connection to the user is provided via dial-up, ISDN, cable, DSL and T1/T3 lines. might have one machine handling mail, one for Web serving, one for DNS (Domain Name System) A system for converting host names and domain names into IP addresses on the Internet or on local networks that use the TCP/IP protocol. For example, when a Web site address is given to the DNS either by typing a URL in a browser or behind the , and multiple machines handling static Web content. If any one machine goes down, then that service is lost. With the cluster technology in Evolocity 1240s, it is possible to eliminate service downtime, while at the same time maximizing the use of system resources. Each compute module in the system handles a portion of each of the services -- so if an individual module fails, only a small portion of overall capacity is lost; there is never a threat of a single service being completely lost. |
