摘要

缺乏I/O性能正迅速成为许多计算系统中的一个限制因素。CPU速度每年翻一番的同时，I/O性能却没有相应的提高。本文探讨了多处理器高性能容错缓存RAID子系统体系结构的一个方面。磁盘写缓存实现为内存映射的稳定内存。讨论了基于vram的稳定存储器及其配套的RAID控制器的特点。

Stable memory for a disk write cache

Lack of I/O performance is fast becoming a limiting factor in many computing systems. The yearly doubling of CPU speeds is not being matched by corresponding gains in I/O performance. This paper explores one aspect of the architecture of a high performance fault-tolerant cached RAID subsystem for a multiprocessor. The disk write cache is implemented as a memory-mapped stable memory. The features of a VRAM-based stable memory and its associated RAID controller are discussed.
