当前,用于关键型业务的计算平台有四种体系结构可供选择,它们是:小型网络服务器:通过网络相连接的多种小型独立服务器;大型SMP节点:运行于一个操作系统下的许多处理器及资源;群集的SMP节点:不同的节点运行同一种操作系统的不同实例,一个应用的多个实例可以运行在不同的节点,但共享某些存储装置和数据;大规模并行处理系统:操作系统和应用程序的许多独特势力运行于各个独立节点,通常没有任何共享资源,并以消息传送的方式进行通讯。
Currently, there are four architectures available for computing platforms for mission-critical services: small network servers: a variety of small, standalone servers connected over a network; large SMP nodes: many processes running on one operating system And resources Cluster SMP nodes: Different nodes run different instances of the same operating system, multiple instances of an application can run on different nodes but share some storage and data Large scale parallel processing systems: operations Many of the unique power of systems and applications run on separate nodes, often without any shared resources, and by messaging.
