摘要： Apparatus, systems and methods for clustering multiple PCI Express hierarchies to enable access of components in different hierarchies. Each PCI Express hierarchy includes a root device as well as a cluster port for coupling each hierarchy to each other hierarchy of a physical cluster through a PCI Express switched fabric. Memory addresses and transaction IDs are re-mapped by the cluster port of each hierarchy to partition the PCI Express space of the system of multiple hierarchies. A first portion of the partitioned space is reserved for access to local components within a hierarchy. A second portion of the space is used to access remote components of other hierarchies from within a different first hierarchy. The address and transaction ID values exchanged in such remote transactions are re-mapped and used by the cluster port of each hierarchy to route exchanges between hierarchies using standard PCIe root devices, endpoint devices, and switches.

摘要： In one embodiment, the present invention provides a storage system controller (10) having a main processor (12), a memory (14) and a device interface (18) adapted to interface with a peripheral component (28-32). The controller further includes an interrupt management scoreboard (24) adapted to receive a plurality of writes from the peripheral component(s) prior to interrupting the main processor. The main processor identifies a group of tasks to be executed, and sets up the scoreboard to await the completion of the tasks before interrupting the main processor.

摘要： Apparatus and circuitry are provided for supporting collection and/or verification of data integrity information. A circuitry in a storage controller is provided for creating and/or verifying a Data Integrity Block (“DIB”). The circuitry comprises a processor interface for coupling with the processor of the storage controller.

摘要： A method for verifying the proper communication of data packets from an initiator device on a PCIe data bus to a target device on the data bus. A target-specific counter on the initiator is synchronized to an initiator-specific counter on the target with the same value. The initiator writes the value of the target-specific counter into the tag field of the packet header, and also writes an identifier of the initiator into the header. Then the initiator sends the packet to the target on the PCIe data bus. Upon receipt of the packet, the target reads the identifier and checks the value against the appropriate initiator-specific counter on the target. When the value is not equal to the initiator-specific counter on the target, then it generates an error message. An additional memory write with specific data is posted from the initiator to the target. A memory read is posted of the additional memory write location from the initiator to the target. The operation of the initiator is continued when a good status and data matching the additional write data is returned from the target, and operation is halted when an error status is returned or data that does not match the additional write data.

摘要： The present invention provides storage system controllers and methods of controlling storage systems therewith. The controller (10) includes a main processor (12), a memory (14), a device interface (18) adapted to interface a peripheral component (28-32), such as a RAID storage device, with the storage system controller, and an operations sequencer (24). The main processor sequences a plurality of tasks to be executed to complete an operation. The operations sequencer coordinates an execution of the plurality of tasks. Methods of the invention include receiving a task status for each of the plurality of tasks that is executed, and issuing an interrupt to the main processor after all of the plurality of tasks of the operation are finished executing. In this manner, the operations sequencer offloads at least some of the main processor overhead to improve processor efficiency.

摘要： Methods and associated apparatus operable in a RAID subsystem to improve the speed and flexibility of initializing the subsystem by storing configuration and identification information in a reserved area on each disk drive in the subsystem. The reserved area on each disk drive of the disk array contains a unique identifier to identify the particular disk drive from all others and further contains group configuration information regarding all groups in which the particular disk drive is a member. The configuration and identification information is generated and written to each disk drive in the disk array when the particular disk drive is configured so as to be added or deleted from groups of the subsystem. Upon subsystem reset (e.g. power on reset or other reset operations), the RAID controller in the subsystem determines the proper configuration of the RAID groups despite temporary unavailability or physical relocation of one or more disk drives in the disk array. In addition, entire groups of disk drives may be moved from one subsystem to another and automatically recognized by the new controller when the controller is reset.

摘要： Apparatus and systems for improved access to storage devices from the sides of sleds mounted in storage enclosures. Embodiments provide apparatus and systems for a sled in a storage enclosure that provides access to storage devices on either side of the sled when the sled is slid forward out of its enclosure. Multiple sleds may be enclosed within a single enclosure to permit access to a portion of the storage devices in the enclosure hence reducing the problems of instability of the rack if the enclosure is mounted near the top of the rack.
