现在的服务器领域存在两种不同的服务器架构,一种是基于 RISC CPU 的 RISC(精简指令集系统计算机)架构服务器;一种是基于 Intel 体系的 IA (IntelArchitecture)架构服务器,即通常所说的PC Server。从八十年代开始,RISC 架构服务器占据了高端计算机的主流地位。但是RISC 架构服务器的技术只被少数几个大公司所垄断,他们推出的是基于自己专有芯片的 RISC 架构服务器,如 IBM 公司的PowerPC 处理器,HP 公司的 PA 处理器,Sun公司的 SPARC 处理器,Compaq 公司的 There are two different server architectures in the server field. One is a RISC (RISC-based RISC) architecture server; the other is an IA architecture-based IA (Intel Architecture) server, which is commonly referred to as a PC Server. Since the eighties, RISC-based servers have dominated high-end computing. However, the RISC-based server technology is dominated by only a few large companies that have introduced RISC-based servers based on their own proprietary chips, such as IBM’s PowerPC processor, HP’s PA processor, Sun’s SPARC processor Compaq company
