IA服务器正不断蚕食着企业关键应用的地盘。与此同时,IA服务器如何使自身的性能得以与大型机媲美已成为其下一步发展的关键。 早在1998年,IBM公司就提出了“X架构”,试图在未来5年内将大型机所使用的一系列先进技术移植到基于工业标准的IA(Intel Architecture)服务器上,从而使IA服务器在可用性、可扩展性和可管理性等方面得以大幅提升。在之后几年中,IBM公司不断用Active PCI、C2T Interconnect连线、Chipkill内存、预测性故障分析光路诊断和IBM Director软件恢复等创新技术实现着自己的承诺。而到了2001年,“企业级X-架构”技术又在I/O、内存等性能方面使IA服务器得以进一步提升。在这些技术当中,XpandOnDemand(按需扩展)、Remote I/O(远程I/O)、Xcel ServerAccelerator Cache XceL4(服务器加速缓存)、Active Meomry(Active内存)是4项来自大型机的主要技术。
IA servers are constantly eating away at the keys to enterprise-critical applications. At the same time, how IA servers make their performance comparable to mainframes has become the key to their next evolution. As early as 1998, IBM Corporation proposed “X Architecture”, attempting to port a series of advanced technologies used by the mainframe to the industry standard IA (Intel Architecture) server in the next five years so as to make the IA server available , Scalability and manageability can be significantly improved. Over the next few years, IBM continued to deliver on its promise with innovative technologies such as Active PCI, C2T Interconnect, Chipkill Memory, Predictive Failure Analysis Optical Path Diagnostics and IBM Director software recovery. By 2001, “Enterprise X-Architecture” technology in the I / O, memory and other performance of the IA server to be further enhanced. Among these technologies, XpandOnDemand (on demand), Remote I / O, Xcel ServerAccelerator Cache XceL4, and Active Meomry are the four main technologies from the mainframe.
