Techniques for efficient mass storage layout optimization
Abstract:
A data storage system can automatically improve the layout of data blocks on a mass storage subsystem by collecting optimization information during both read and write activities, then processing the optimization information to limit the impact of optimization activities on the system's response to client requests. Processing read-path optimization information and write-path optimization information through shared rate-limiting logic simplifies system administration and promotes phased implementation, which can reduce the difficulty of developing a self-optimizing storage server.
