IMPLEMENTING MULTI-TENANCY QUALITY OF SERVICE USING CONTROLLERS THAT LEVERAGE DISK TECHNOLOGIES

摘要

An integrated controller for implementing a quality of service when storing input/output data across an array is provided. The integrated controller receives the input/output data from at least one of a file system and an upper layer application. The input/output data can be associated with a quality of service classification. The integrated controller also splits the input/output data into data chunks and determines whether the quality of service classification indicates a first priority or a second priority for each of the data chunks. Then, if the quality of service classification indicates the first priority, the integrated controller proceeds to place the data chunks across a first partition of a disk of the array.
