优化服务器性能的挑战性工作之一,就是提供能充分发挥新处理器体系性能潜力的内存和 I/O 子系统。传统的行业标准服务器设计遇到了性能扩展到4路以上的瓶颈,这是因为传统的方法中处理器和 I/O 总线的拥挤以及内存利用不充分造成的。当服务器硬件平台使用了增强的、高性能动态多处理(SMP)构件模块,可以有效地将服务器群集扩展到4路以上。这些技术提供了高扩展能力,利用4路“可扩展企业节点”,可以扩展提供4路、8路甚至16路。一个可扩展企业节点包括处理器、内存、I/O 支持组件、存储器和其他设备,它像其它计算机一样独立运行。每个节点运作的操作系统可以和其他节点不同,通过系统分区,多个节点也可以分配同一个操作系统映像。节点之间通过专用
One of the challenging tasks for optimizing server performance is to provide memory and I / O subsystems that take full advantage of the performance capabilities of the new processor system. Traditional industry-standard server designs have encountered performance bottlenecks that extend beyond 4 because of the crowding of processors and I / O buses and inadequate memory utilization in traditional methods. When the server hardware platform uses an enhanced, high-performance Dynamic Multiprocessing (SMP) building block, it can effectively scale server clusters to more than four. These technologies provide high scalability with 4 “scalable enterprise nodes” that can be expanded to provide 4, 8, or 16 channels. A scalable enterprise node consists of a processor, memory, I / O support components, memory, and other devices that operate independently of other computers. Each node operating system and other nodes can be different, through the system partition, multiple nodes can also be assigned the same operating system image. Passed between nodes
