Functional partitioning method for providing modular data storage systems

摘要

A modular data storage system with a control path and a data path. The storage system includes three modular components linked and adapted for independent removal and insertion within the modular data storage system. A service processor is positioned in the control path, a data services platform is positioned in the data path and the control path, and a storage array controller is positioned in the data path and the control path. The data services platform has a host interface interfacing with storage application hosts and includes a control path block linked to the service processor. The platform includes a data path block including data path functions that may be functions partitioned for performance only by the data services platform. The storage array controller includes a control path block linked to the service processor and including control interfaces. The controller includes a data path block including data path functions.
