Abstract:
1. A system to provide secondary data storage and recovery services to at least one networked host node storing data in an array of primary storage devices each coupled to the at least one host node by dedicated data paths, comprising: a host node to connect at least one of a primary storage device and a secondary storage subsystem to a network to acquire data; the primary storage to store the data generated by the host node; the secondary storage subsystem including a server executing a server application managing data backup and recovery services by the secondary storage subsystem, wherein the secondary storage subsystem is comprised of at least one of a dedicated server node and a PC node, and wherein the data is received by at least one of a specially adapted line card installed in the secondary storage subsystem and a network adaptor card; and at least one data path splitter installed one per dedicated data path existing between the at least one host and the primary storage device, wherein the splitter mirrors data transmitted in the dedicated data paths, and streams the mirrored data to the secondary storage subsystem, wherein the data path splitter is comprised of a hardware data splitter of at least one of an optical type and an electrical type, depending on the type of network line used.
