摘要： An apparatus, system, and method are disclosed for copying data from a volatile memory device to a plurality of persistent storage devices in response to a loss of primary power. The apparatus includes a section module, a stripe module, and a write module. The section module sections a data image of a write cache into a plurality of data blocks. The stripe module establishes a plurality of data stripes from the plurality of data blocks. The write module writes in parallel each of the plurality of data stripes to a corresponding plurality of unique, persistent data storage devices in response to a loss of line power to the write cache. Advantageously, the apparatus quickly copies the write data from the write cache to a persistent memory device in a relatively short period of time, decreasing the dependence on significant batteries to back up the volatile memory device.

摘要： Provided are a method, system, and article of manufacture for maintaining information of a relationship of target volumes comprising logical copies of a source volume. Information is maintained on a source volume having a plurality of data units and a plurality of target volumes created at different points-in-time maintaining a logical copy of the data units in the source volume for the different points-in-time. A source downstream pointer is generated for each data unit in the source volume to point to a corresponding data unit in a first target volume. For each target volume data unit whose data is maintained in the source volume or another one of the target volumes, a first upstream pointer is generated indicating one of the source and target volumes from which the target volume data unit inherits data. For each target volume data unit whose data is maintained in the source volume or another one of the target volumes, generating a second upstream pointer indicating one of the source and target volumes having the data for the data unit.

摘要： Disclosed is a method, system, and article of manufacture for processing modified meta data for data recovery operations. The meta data provides information on user data maintained in a storage device. The system determines whether meta data tracks maintained in a cache were modified and indicates in a non-volatile memory that the determined meta data tracks were modified. Data recovery operations may be initiated as a result of a system failure, such as a warmstart or coldstart recovery. During such data recovery operations, the system processes the non-volatile memory and the indications of modified meta data tracks therein to rebuild lost meta data tracks in the cache.

摘要： A method and system to verify the passage of one or more write commands sent from an originating location through a PCI bus system. An addressable data storage is located substantially at the end of the PCI bus system with respect to the originating location. A write command is sent by the originator subsequent to the one or more write commands, to a predetermined special end location address identifying the addressable storage. The command is accompanied by data comprising a predetermined special return address at the originating location. The PCI bus system transmits the write commands on a FIFO basis, so the one or more write commands precede the subsequently sent write command. Logic senses the subsequently sent write command, and responds to the command, sending a return echo write command to the predetermined special return address. The returning echo write command verifies the passage of the write commands and data through the PCI bus system. The predetermined special end location address is the key to identify the subsequently sent write command.

摘要： Disclosed is a method, system, and article of manufacture for managing meta data. The meta data provides information on data maintained in a storage device. The system receives a request for meta data from a process and determines whether the requested meta data is in cache. After determining that the requested meta data is not in cache, the system determines whether there are a sufficient number of allocatable segments in cache to stage in the meta data and allocates segments in cache to store the meta data after determining that there are enough allocatable segments in cache. The system stages the requested meta data into the allocated segments. Alternatively, after determining that the requested meta data is in cache, the system determines whether a second process has exclusive access to the meta data in cache. After determining that the second process does not have exclusive access, the system indicates to the first process that access to the meta data is permitted. Otherwise, after determining that the second process has exclusive access, the system notifies the first process that access to the meta data track will be provided at a later time when the second process relinquishes exclusive access.

摘要： A system and method for flushing stale data from a read prefetch buffer of a PCI bus system which transfers data in the form of data streams of contiguous blocks. The PCI bus system comprises a channel adapter at one PCI bus that issues read commands, a data source coupled to a second PCI bus, and a prefetch buffer that prefetches the blocks of read data. A prefetch counter posts the remaining number blocks to be read and transferred, posting the prefetch count at a storage location of a storage memory mapped to a prefetch location in the prefetch buffer. The prefetch count is written to the storage location by a prefetch count write command. The system for flushing stale data from the prefetch buffer comprises a key detector for sensing an unique identifier of the prefetch count write command. Data path logic responds to the key detector, determining the prefetch location of the prefetch buffer from the mapped storage location of the prefetch count write command, and flushing any prefetch data at the determined prefetch location.

摘要： Disclosed is a system for handling errors. A system managed by a processor processes an error in the system. The system then generates an interrupt to the processor indicating that an error occurred and executes an error mode before the processor interprets the interrupt. As part of the error mode, the system prevents data from transferring between the system and the processor and processes a read request from the processor to the system by returning data to the processor unrelated to the requested data. The processor would then process the interrupt indicating the error and execute a diagnostic mode to diagnose the error in the system.
