  • Patent number: 9257151
    Abstract: Described is a printed-circuit board (PCB) that supports memory systems in which the memory core organization changes with device width. The PCB includes a memory-controller mounting location and module connectors to receive respective memory modules. Each module connector connects directly to the controller mounting location via a respective set of system data lines that does not connect to any other module connector. System data lines also extend directly between module connectors to support memory configurations with different numbers of modules. The memory systems support one memory module of a wide data width or multiple memory modules of narrower data widths. The number of physical memory banks accessed reduces with device data width, resulting in reduced power usage for relatively narrow memory configurations. Increasing the number of logic memory banks for narrow memory widths reduces the likelihood of bank conflicts, and consequently improves speed performance.

  • Patent number: 9092470
    Abstract: Certain example embodiments relate to a method of storing data in a tabular data structure having columns and rows in a column-oriented storage system. At least one of the columns is divided into a plurality of segments. Each segment has an associated cell size that indicates the maximum size of the data items in the respective segment. When storing a data item into one of the segments, it is determined whether the size of the data item exceeds the cell size of the segment; and if the size of the data item exceeds the cell size of the segment, the cell size of the segment is adapted to accommodate the size of the data item. The adapting of the cell size of the segment to accommodate the size of the data item is performed independent of the cell sizes of the other of the plurality of segments.

  • Patent number: 9043573
    Abstract: Various systems and methods are described for configuring a logical data storage container. In one embodiment, an instruction to perform an operation to modify an attribute of the logical data storage container that is an abstraction of a plurality of pertinent storage containers is received. A translated instruction to perform a sub-operation associated with the operation is transmitted to each of a number of the plurality of pertinent storage containers. A level of success of the performing of the operation on the logical data storage container is detected based on a comparison of a threshold value to a level of success of the performing of the sub-operation on each of the number of the plurality of pertinent storage containers. A report of the detected level of success is communicated.

  • Patent number: 8995070
    Abstract: An execution environment for functional code may treat application segments as individual programs for memory management. A larger program of application may be segmented into functional blocks that receive an input and return a value, but operate without changing state of other memory objects. The program segments may have memory pages allocated to the segments by the operating system as other full programs, and may deallocate memory pages when the segments finish operating. Functional programming languages and imperative programming languages may define program segments explicitly or implicitly, and the program segments may be identified at compile time or runtime.

  • Patent number: 8990527
    Abstract: Releasing a data set at a source device in connection with migrating data from the source device to a target device includes mapping application address space to address space containing metadata for the target device and providing additional local metadata therefor, replacing within the application the address of metadata for the source device with the address of metadata for the target device, setting a diversion flag that is part of the additional local metadata, where the diversion flag indicates a remapping of extent, and closing and unallocating the data set at the source device. Releasing a data set at a source device in connection with migrating data from the source device to a target device may also include determining if an application uses standard I/O operations. The metadata may include UCB data.

  • Patent number: 8972694
    Abstract: A write operation writes first data to a target logical address range included in a first logical address range of a virtually provisioned device. It is determined that physical storage is not allocated for the target logical address range. First processing is performed to allocate a first portion of physical storage having a first corresponding logical address subrange that includes the target logical address range. The first portion is allocated from a physical device included in a first storage tier. The first processing includes selecting the first storage tier from multiple storage tiers in accordance with selection criteria including metrics characterizing an expected workload or level of activity for the first corresponding logical address subrange of the virtually provisioned device. Mapping information is updated to indicate that the first corresponding logical address subrange of the virtually provisioned device maps to the first portion of physical storage.

  • Patent number: 8966218
    Abstract: A method for predictively allocating space in a database system includes detecting an access request for a data set, evaluating a growth rate of the data set to determine a predicted increase in size of the data set, and in response dynamically altering an attribute of an allocation for the data set. Attributes altered include the size of volumes and the number of volumes comprising the data set. The method may include setting a flag indicating an instruction to rewrite the data set if the evaluation indicates that rewriting is needed to accommodate the predicted increase in size. The method may include rewriting the data set from a lower address space of a volume to a higher address space of the volume if the size of the data set is equal to or greater than an allocation increment of the upper address space. A corresponding apparatus and computer program product are also disclosed herein.

  • Patent number: 8943293
    Abstract: A method includes receiving an address at a tag state array of a cache, wherein the cache is configurable to have a first size and a second size that is smaller than the first size. The method further includes identifying a first portion of the address as a set index, wherein the first portion has a same number of bits when the cache has the first size as when the cache has the second size. The method further includes using the set index to locate at least one tag field of the tag state array, identifying a second portion of the address to compare to a value stored at the at least one tag field, locating at least one state field of the tag state array that is associated with a particular tag field that matches the second portion, identifying a cache line based on a comparison of a third portion of the address to at least one status bit of the at least one state field when the cache has the second size, and retrieving the cache line.

  • Patent number: 8935500
    Abstract: Distributed storage resources having multiple storage units are managed based on data collected from online monitoring of workloads on the storage units and performance characteristics of the storage units. The collected data is sampled at discrete time intervals over a time period of interest, such as a congested time period. Normalized load metrics are computed for each storage unit based on time-correlated sums of the workloads running on the storage unit over the time period of interest and the performance characteristic of the storage unit. Workloads that are migration candidates and storage units that are migration destinations are determined from a representative value of the computed normalized load metrics, which may be the 90th percentile value or a weighted sum of two or more different percentile values.
