摘要： Storage gateway remote and local access to storage devices is provided in part via a target implementing bandwidth-controlled access to the devices. The target may be iSCSI-compatible, and may also optionally implement protection, security, and performance features. The protection and security features include any combination of VLANs, zoning, Logical Unit Number (LUN) masking, and encryption. The performance features include any combination of HW-accelerated Remote Direct Memory Access (RDMA), prioritized I/O operations, and service priority (such as strict priority and straight or weighted round-robin priorities). An initiator may be implemented in a Processor Memory Module (PMM) coupled to a switch fabric that is in turn coupled to a target implemented in a Fibre Channel Module (FCM). Storage traffic may be communicated as Small Computer System Interface (SCSI)- and SCSI over Transmission Control Protocol/Internet Protocol (iSCSI)-compatible information (data and commands) on the switch fabric via cellifying input/output interface devices.

摘要： A plurality of SMP modules and an IOP module communicate storage traffic via respective corresponding I/O controllers coupled to respective physical ports of a switch fabric by addressing cells to physical port addresses corresponding to the physical ports. One of the SMPs executes initiator software to partially manage the storage traffic and the IOP executes target software to partially manage the storage traffic. Storage controllers are coupled to the IOP, enabling communication with storage devices, such as disk drives, tape drives, and/or networks of same. Respective network identification registers are included in each of the I/O controller corresponding to the SMP executing the initiator software and the I/O controller corresponding to the IOP. Transport of the storage traffic in accordance with a particular VLAN is enabled by writing a same particular value into each of the network identification registers.

摘要： Storage gateway provisioning, configuration, and management functions provide mechanisms to specify and manage parameters and operations associated with storage gateways. The parameters may include any combination of VLAN topology, zoning behavior, LUN masking, bandwidth, and priority. The parameters may also include path information describing initiator to target associations, enabling load-balancing aggregations and multipathing redundancy. Parameters may be specified at relatively low-levels, describing specific HW elements, or may be specified at relatively high-levels, describing desired bandwidth and redundancy requirements, with SW determining low-level HW assignments. Configuration and management functions enable dynamic modification of storage gateway parameters (such as bandwidth between selected initiator and target pairs). Management functions also enable dynamic switchover from a primary path to a secondary path with respect to a storage device.

摘要： A data processing system and method provide for sharing a partition of a memory in the system between a first task and thread and a second task and thread, so as to more efficiently enable adaptive sharing of data for local tasks or alternately copying of data into I/O buffers for remote tasks. The system and method automatically determine whether sharing has been established between two local tasks and if not, the system and method will adaptively copy data for messages to be transferred between the tasks.

摘要： In one aspect, initial storage system control information is received, and in response a configuration of a storage interface is determined in accordance with the initial storage system control information. Then final storage system control information is accessed via the storage interface and the storage interface is reconfigured in accordance with the final storage system control information. In another aspect, one of a plurality of physical partitions of a physically partitionable symmetric multiprocessor executes a storage control process to control storage traffic, and another one of the physical partitions executes a program to process the storage traffic. The physical partitions are enabled to communicate the storage traffic at least in part via respective input/output controllers coupled to a switch fabric. The partitionable symmetric multiprocessor has programmatically configurable links for selectively isolating shared memory coherency and cache memory coherency transactions between at least some included processors.
