    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： Methods and structure for an improved solid-state drive (SSD) for use in caching applications. An improved SSD comprises both volatile and non-volatile memory. The volatile memory provides improved performance as compared to present SSDs for use in caching application. The improved SSD senses impending failure of external power applied to the SSD and, while adequate power remains, copies cached data from the volatile memory to the non-volatile memory to retain the data through the power loss. In some embodiments, a local power source may be present to assure sufficient time for the SSD to save cached data in the non-volatile memory. Since the volatile memory (e.g., DRAM) is used for the primary caching function and the non-volatile memory is rarely used, performance, reliability and cost goals are achieved for write cache applications.

    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.

    摘要： A system for isolating a faulty switch or respective storage device from a plurality of switches and respective storage devices in a daisy-chained arrangement. In the daisy-chain arrangement the switches are connected in sequence to permit access to the respective storage devices through the preceding switches in the sequence. All of the switches, except one, are set in a bypass mode where they do not read inputs of the respective storage devices. The one switch is set in a non bypass mode where it reads an input from its associated storage device. A status of the daisy-chain, either up or down, is then determined. If the status is up, the foregoing steps are repeated a number of iterations with a different one of the switches being set in a non bypass mode and the other switches being set in the bypass mode during each iteration, until the status of the daisy-chain is down. The down status indicates that the switch which is set in the non bypass mode or its associated storage device is defective.

    摘要： A reset circuit implemented in a RAID controller configured for dual active operation. The reset circuit generates a reset pulse with a relatively invariant pulse width that is coupled to the controller's main CPU and I/O processors. The reset pulse can be generated in response to activation of an external common reset signal. The external common reset signal is activated by an external system (e.g., another controller configured for dual active operation) whenever the controller needs to be reset. This can be when the controller fails to maintain a communication signal transmitted to the external system or when the external system has inconsistent configuration information, requiring the entire system (i.e., both the controller and the external system) to be re-initialized. The reset pulse can also be generated in response to internal reset instructions issued by the controller's main CPU. The reset instructions can be issued whenever the first controller determines that its own configuration information is inconsistent. As a result of the reset instruction being issued the external common reset signal is activated as an output to reset the external system (i.e., the external common reset signal is bidirectional). The self-reset operation can be over-ridden by a reset disable instruction.
