Abstract: An improved system and method within a storage area network (SAN) for establishing predictive grouping and presentation of target devices contained within the same physical enclosure(s) in an iSCSI/iSER to SAS/SATA storage router. Target devices within an enclosure are dynamically discovered in slot order and placed in an iSCSI/iSER storage node to facilitate access by SAN initiator devices.

Abstract: A system and method for accelerating iSCSI storage traffic on a TCP/IP network over Ethernet. Ethernet storage frames are classified and deconstructed entirely in hardware by the use of a frame correlation engine, a TCP frame dissector and a number of protocol engines, providing iSCSI command processing without the involvement of a network protocol stack or TCP offload engine.

Abstract: The present invention provides an improved device, system and method for representation of target devices in a storage router. In one aspect, a device, system and method are provided for predictive representation of SAS/SATA-based target devices in a storage router corresponding to the physical layout of the target devices. In another aspect, a storage router is communicatively connectable to a plurality of target storage devices. In one embodiment, a router discovery manager or module is configured to discover the physical layout of the target storage devices; a host system interface receives and responds to data storage commands; a computer bus interface connects/communicates with SAS and SATA storage; and a plurality of host system interface to target storage device maps correspond to the physical layout of the target storage devices.

Abstract: The present invention provides an improved method and system of improving the efficiency, and ensuring the integrity, of a data transfer in a serverless backup, or third party copy, system having one or more physical storage devices. The present invention provides improvements to the processing of serverless copy, or EXTENDED COPY, commands, and transfers of data associated with such commands. These improvements increase the speed at which such commands are executed and completed, and increase the capabilities of copy managers in serverless backup systems. The improvements also make better use of the storage devices involved in the data backup process. Certain aspects of the invention allow for execution of data segments of any size, and providing a compiler for generating input/output actions.

The method broadly includes determining a desired manner of execution of segment descriptors, or instructions, as a function of components of those instructions. Other aspects of the invention allow for execution of data segments of any size, and validation of segment descriptors and target descriptors prior to data transfer.

Abstract: In association with a storage system, dividing or splitting file system I/O commands, or generating I/O subcommands, in a multi-connection environment. In one aspect, a host device is coupled to disk storage by a plurality of high speed connections, and a host application issues an I/O command which is divided or split into multiple subcommands, based on attributes of data on the target storage, a weighted path algorithm and/or target, connection or other characteristics. Another aspect comprises a method for generating a queuing policy and/or manipulating queuing policy attributes of I/O subcommands based on characteristics of the initial I/O command or target storage. I/O subcommands may be sent on specific connections to optimize available target bandwidth. In other aspects, responses to I/O subcommands are aggregated and passed to the host application as a single I/O command response.
