数据传输一直以来是 IA 架构服务器的一个弱点,因为 CPU 处理能力的提高速度远远比磁盘和网络 I/O 快得多。为了适应人们对 IA 架构服务器新的需求,IA 架构服务器的体系结构正在发生着巨大变革,导致产生这种变革的根本方法并不是在处理器内嵌入二级(L2)高速缓存以提高访问速度,而是设法改善它的薄弱环节——I/O 性能。下面,介绍一下 I_2O 对 I/0性能的改善:I_2O 规范(智能化输入/输出规范)的提出和开发是为了满足在不同种类的操作系统间及在各种主机平台之间移植设备驱动程序的强烈要求和对分布式、智能化输入/输出处理的日益高涨的要求。
Data transfer has long been a weakness for IA architecture servers because CPU processing power is much faster than disk and network I / O. In response to new demands on IA-based servers, the architecture of IA-based servers is undergoing dramatic changes, and the underlying approach to making such changes is not to embed second-level (L2) caches in processors to speed up access, Instead, try to improve its weakness - I / O performance. Here’s how I_2O improves I / O performance: The I_2O specification (Intelligent Input / Output Specification) has been proposed and developed to address the need to migrate device drivers between different operating systems and host platforms Strong demand and increasing demands for distributed, intelligent I / O processing.
