    摘要： An apparatus for limiting volatile computer memory based on available energy in an auxiliary power source comprises an energy monitor module configured to determine an amount of available energy in the auxiliary power source. Also provided is a memory status module configured to determine an amount of volatile computer memory allocated for use in a computer and a memory adjustment module configured to adjust the amount of volatile computer memory allocated for use in the computer based on the amount of available energy in the auxiliary power source. A startup module may be configured to allow the computer to begin moving data normally when the memory adjustment module limits volatile computer memory allocated for use by the computer to a minimum level and the energy monitor module determines that the amount of available energy in the auxiliary power source has reached a minimum level capable of transferring the volatile computer memory allocated for use by the computer to non-volatile computer memory during a computer shutdown.

    摘要： A method and system for controlling access to a bus for transferring data in the form of multibyte data streams. Data transfer agents are coupled to and request access to the bus to transfer data thereon. The system for controlling access to the bus comprises a bus arbiter responsive to the access requests of the data transfer agents, granting access to the bus to one data transfer agent at a time. A data length counter accumulates, during the grant of access, signals indicating the length of the data transferred between the bus and the data transfer agent. The data length counter indicates completion of the transfer of a predetermined length of data, and bus arbiter logic responds to the data length counter indicating the transfer completion, causing the bus arbiter to terminate the grant of access to the data transfer agent. The control of access to the bus is thus based on the precise measurement of the length of the transferred data, rather than on timers.

    摘要： A system and method track and control the prefetching of blocks of a data stream in a PCI bus system, avoiding unnecessary prefetches. The data stream is grouped into major blocks which comprise a fixed plurality of contiguous blocks. A prefetch buffer stores the blocks of data prefetched from a PCI data source for transfer to a requester. First and second associated prefetch count storage locations store first and second counts initialized by prefetch initialization logic. The first count represents the number of blocks of data of a major block of the data, and the second count represents the total number of the blocks of the data stream to be prefetched, less the initialized number of blocks of the first count. As each block of data is prefetched, a prefetch counter decrements the first count by a number representing the block of data. As the prefetch counter decrements the first count to zero, prefetch count logic stops the prefetch, allowing completion of the transfer of the prefetched data to the data destination. Thus, the second count represents the next remaining number of blocks to be prefetched, and the requester can rotate to a different read request at the end of a major block, knowing the next major block will not be prefetched until requested.

    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.

An image of data is maintained in a memory, wherein the image in the memory includes a generation number. The image in the memory is written to at least two copies of the image to storage locations in response to a first event, wherein the generation number for the image in the memory is stored in the storage locations having the copies of the image. A check generation number is stored in a storage location. The image is loaded from at least one of the copies of the image in one of the storage locations to the memory in response to a second event The generation number for the image loaded into the memory. The check generation number is incremented in response to the second event. The generation numbers for the copies of the image in the storage locations and the check generation number are used to validate the copies of the image.

    摘要： A method, system, and computer program product for preserving data in a storage subsystem having dual cache and dual nonvolatile storage (NVS) through a failover from a failed cluster to a surviving cluster is provided. A memory preserved indicator is initiated to mark tracks on a cache of the surviving cluster to be preserved, the tracks having an image in an NVS of the failed cluster. A destage operation is performed to destage the marked tracks. Subsequent to a determination that each of the marked tracks have been destaged, the memory preserved indicator is disabled to remove the mark from the tracks. If the surviving cluster reboots previous to each of the marked tracks having been destaged, the cache is verified as a memory preserved cache, the marked tracks are retained for processing while all unmarked tracks are removed, and the marked tracks are processed.

    摘要： A computational device allocates a plurality of solid state disks to a plurality of redundant array of independent disk (RAID) ranks, wherein a different solid state disk is absent in each RAID rank of the plurality of RAID ranks. The computational device determines at least one selected solid state disk from the plurality of solid state disks, wherein the at least one selected solid state disk is estimated to have undergone a greater amount of wear in comparison to other solid state disks in the plurality of solid state disks. Relatively more data and parity information is written to those RAID ranks in which the at least one selected solid state disk is absent in comparison to those RAID ranks in which the at least one selected solid state disk is present.
