Abstract

A modular data storage system (110) with a control path and a data path. The storage system (110) includes three modular components linked and adapted for independent removal and insertion within the modular data storage system (110). A service processor (114) is positioned in the control path, a data services platform (120) is positioned in the data path and the control path, and a storage array controller (130) is positioned in the data path and the control path. The data services platform (120) has a host interface (122) interfacing with storage application hosts (150) and includes a control path block (124) linked to the service processor (114). The platform (120) includes a data path block (128) including data path functions that may be functions partitioned for performance only by the data services platform (120). The storage array controller (130) includes a control path block (132) linked to the service processor and including control interfaces. The controller (130) includes a data path block (134) including data path functions.
