摘要： A method is disclosed to set the signaling rate of a switch domain disposed in an information storage and retrieval system. The method establishes a switch domain target operating speed, and determines if that switch domain target operating speed comprises a first signaling rate. If the switch domain target operating speed comprises a first signaling rate, then the method asserts first Device Control Code bits to each of the plurality of data storage devices, and each of the plurality of data storage devices communicates with the switch using that first signaling rate. If the switch domain target operating speed does not comprise the first signaling rate, then the method asserts second Device Control Code bits to each of the plurality of data storage devices, and each of the plurality of data storage devices communicates with the switch using a second signaling rate.

摘要： A serial SCSI (SAS) storage drive system includes a drive enclosure having a first interface card coupled to one storage controller over a single SAS path and a second interface card coupled to another storage controller over a different single SAS path. At least one disk drive within the enclosure is assigned to the first storage controller and interconnected to the storage controller through the first interface card. At least a second disk drive within the enclosure is assigned to the second storage controller and interconnected to the storage controller through the second interface card. The interface cards are selectively interconnected with each other through a crossover port. In the event of a failure in a storage controller or an interface card, the crossover port may be activated, thereby maintaining access to both sets of disk drives.

摘要： In a RAID storage system, a parity value is generated. The storage system includes a RAID adapter, a plurality of disk array processors managing corresponding sets of RAID storage drives, and a connecting fabric. The RAID adapter initiates a parity generation operation, parallel instructions are dispatched for the array processors to each generate a partial parity value from data blocks on drives on respective managed RAID storage drives, the partial parity value is received in the RAID adapter from each array processor, and the partial parity values are combined in the RAID adapter to generate a complete parity value. The parity value may be an actual parity block to be stored on a hard disk drive or may be a reconstructed data block in the event of a failed drive.

摘要： A method of operation of a computer system having a master and slave Inter-IC (I2C) bus network includes detecting and isolating an I2C bus failure, configuring a failed I2C bus as offline, reconfiguring a remaining I2C bus as a multi-mastered bus, and masking the failed I2C bus from operation until the failed I2C bus can be repaired. A first test request is sent to a remote device from a local device. If the remote device receives the first test request, a remote bus mode is switched to a failure position, a local bus mode is switched to a multi-master position, and a second request is sent to the remote device to indicate position changes.

摘要： A data storage domain is provided to determine a set of signal conditioning parameters for data being transmitted over smart cables in a data storage domain between an SAS switch and SAS expanders and among SAS expanders. A first expander interrogates any attached smart cables for cable persistent data and captures in a table the cable persistent data. One or more interfaces of the first expander are operated at a first data rate. The switch collects the captured cable persistent data and, in response, determines a set of signal conditioning parameters for data being transmitted on each attached smart cable. The set of signal conditioning parameters includes a first maximum data rate for each attached smart cable. The signal conditioning parameters are then set for each attached smart cable in accordance with the set of determined signal conditioning parameters, whereby the data storage domain is tuned for optimum signal transmission.

摘要： A high density storage enclosure includes a plurality of storage devices, such as hard disk drives, positioned within a cooling airflow. Data to be stored to a storage device is received and a determination is made as to the expected usage of the data relative to other data stored on devices within the enclosure. The data is stored in a device having a position within the airflow relative to the source of the airflow in direct relationship to the relative expected usage of the data. Thus, data having a higher expected usage is stored in a device closer to the airflow source relative to other data having a lower expected usage and data having a lower expected usage is stored in a device farther from the airflow source relative to other data having a higher expected usage. Additionally, data may be dynamically relocated based upon actual usage.

摘要： A computer-implemented method replaces a redundant array of independent disks (RAID) array member storage device configured in high density packaging. The high density packaging includes a plurality of field-replaceable units (FRUs). Each FRU has an associated plurality of storage devices. A first spare storage device of a first FRU is captured. The first FRU is dedicated as a plurality of spare storage devices by a RAID controller. A small computer system interface (SCSI) enclosure services (SES) processor (SESP) is initialized to read data from the RAID array member storage device and transfer the data to the first spare storage device. The first spare storage device and the RAID array member storage device are co-resident within a serial attached small computer system interface (SAS) expander local port domain.
