内容摘 要：Solid State Disks (SSD) are emerging as a disruptive storage technology. Flash SSDs are not just fast disks, but exhibit a different set of characteristics that will impact both performance and architecture of data intensive software systems. Key characteristics of Flash SSDs compared to magnetic disk drives are: very low latency, high read performance, much lower write performance and very low energy consumption.The long- term impact on software systems and the potential of flash technology have been insufficiently investigated. It is well known that existing concurrency control approaches, optimization techniques, buffer management strategies, access paths and in essence the whole DBMS architecture are designed to compensate for the access gap between memory and disk. To make full use of the characteristics of flash SSDs, the existing architectural fundamentals need to be critically reevaluated.
