Abstract: Disclosed is a microprocessor based system with a dynamically selectable Operating System that is capable of providing unique operating systems based upon current hardware states without user intervention. The system will determine the current state of the system and select from a plurality of operating systems the best operating system to load. In normal operating conditions the system will select the most full-featured and robust operating system. If, for example, the system loses alternating-current power, the system will shutdown, reboot, and automatically select an operating system with very limited capabilities and limited power consumption to allow the system to retrieve important data from the cache and store the data to a data storage device.

Abstract: Disclosed is a method of detecting a product data error in a storage system. First and second vital product data (VPD) EEPROMs are read. Indicators of whether wither or both reads failed are received. Based on these indicators, the contents of the VPD EEPROMs may be compared. Based on a result of the comparing indicating a match, an arbitrary one of the VPD EEPROMS is used. Based on an indicator indicating an error with the first VPD EEPROM, the second VPD EEPROM is used.

Abstract: Data of a vector storage request pertaining to one or more disjoint, non-adjacent, and/or non-contiguous logical identifier ranges are stored contiguously within a log on a non-volatile storage medium. A request consolidation module modifies one or more sub-requests of the vector storage request in response to other, cached storage requests. Data of an atomic vector storage request may comprise persistent indicators, such as persistent metadata flags, to identify data pertaining to incomplete atomic storage requests. A restart recovery module identifies and excludes data of incomplete atomic operations.

Abstract: A method and apparatus for storing data packets in two different logical erase blocks pursuant to an atomic storage request is disclosed. Each data packet stored in response to the atomic storage request comprises persistent metadata indicating that the data packet pertains to an atomic storage request. In addition, a method and apparatus for restart recovery is disclosed. A data packet preceding an append point is identified as satisfying a failed atomic write criteria, indicating that the data packet pertains to a failed atomic storage request. One or more data packets associated with the failed atomic storage request are identified and excluded from an index of a non-volatile storage media.

Abstract: An aggregation module combines a plurality of logical address spaces to form a conglomerated address space. The logical address spaces comprising the conglomerated address space may correspond to different respective storage modules and/or storage devices. An atomic aggregation module coordinates atomic storage operations within the conglomerated address space, and which span multiple storage modules. The aggregation module may identify the storage modules used to implement the atomic storage request, assign a sequence indicator to the atomic storage request, and issue atomic storage requests (sub-requests) to the storage modules. The storage modules may be configured to store a completion tag comprising the sequence indicator upon completing the sub-requests issued thereto. The aggregation module may identify incomplete atomic storage requests based on the completion information stored on the storage modules.

Abstract: A storage controller is configured to implement an atomic storage operation comprising a plurality of separate storage operations on a non-volatile storage medium. The storage controller may store persistent indicators to identify data that pertains to the atomic storage operation. An invalid shutdown may occur before the atomic storage operation is complete. A restart and recovery operation comprises a first scan of the non-volatile storage medium to identify data of the failed atomic storage operation. A physical trim note is stored on the non-volatile storage medium to identify the data of the failed atomic storage operation. The data may be identified by media address. Storage metadata is reconstructed in a second scan, which excludes the data and/or operations of the failed atomic storage operation.
