摘要： Methods and systems for encoding and/or decoding digital signals representing serial attached SCSI (SAS) out of band (OOB) signals exchanged over an optical communication between two SAS devices. A SAS OOB signal to be transmitted from a first SAS device to a second SAS device is first encoded as a digitally encoded signal representing the analog SAS OOB signal and then transmitted over an optical communication medium to another SAS device. A receiving SAS device coupled to an optical communication medium decodes a received digitally encoded signal to detect a received, encoded SAS OOB signal and processes the received SAS OOB signal when receipt is detected. The digitally encoded signal may comprise an idle word portion and a burst word portion to represent various SAS OOB signals. Further, the digitally encoded signal may be precomputed in a variety of disparity forms and stored in a memory for lookup and retrieval.

摘要： Apparatus and methods for improved region lock management in a storage controller. A region lock management circuit coupled with a memory is provided for integration in a storage controller. One or more I/O processor circuits of the storage controller transmit requests to the region lock management circuit to request a temporary lock for a region of storage on a volume of the storage system. The region lock management circuit determines whether the requested lock may be granted or whether it conflicts with other presently locked regions. Presently locked regions and regions to be locked are represented by region lock data structures. In one exemplary embodiment, the region lock data structures for each logical volume may be stored as a tree data structure. A tree assist circuit may also be provided to aid the region lock management circuit in managing the region lock tree data structures.

摘要： A method and apparatus for taking a snapshot of a storage system employing a solid state disk (SSD). A plurality of mapping tables in the SSD store data needed to create a one or more point in time snapshots and a current view of the SSD. In response to a write command, the SSD executes its normal write process and updates its mapping tables to indicate the current view of the SSD and additionally retains the original data in a table of pointers to the original data, as the snapshot of an earlier state of the SSD. In the preferred embodiment, the innate ability of SSDs to write data to a new location is used to perform a point-in-time copy with little or no loss in performance in performing the snapshot.

摘要： At least one first numbered phy of a first SAS expander is grouped with at least one second numbered phy of a second SAS expander physically separate from the first SAS expander into at least one common SAS wide port. An identical SAS address is assigned to the first SAS expander and the second SAS expander for operating the first SAS expander and the second SAS expander to behave and respond as a single, cohesive SAS expander. The first SAS expander is directly connected to the second SAS expander for inter-expander communications.
