    摘要： Provided are a computer program product, system, and method for replicating tracks from a first storage to a second and third storages. A determination is made of a track in the first storage to transfer to the second storage as part of a point-in-time copy relationship and of a stride of tracks including the target track. The stride of tracks including the target track is staged from the first storage to a cache according to the point-in-time copy relationship. The staged stride is destaged from the cache to the second storage. The stride in the cache is transferred to the third storage as part of a mirror copy relationship. The stride of tracks in the cache is demoted in response to destaging the stride of the tracks in the cache to the second storage and transferring the stride of tracks in the cache to the third storage.

    摘要： Method, apparatus, and computer program product embodiment for allocating a plurality of extents in a thinly provisioned computing storage environment are provided. In one such embodiment, subsequent to a write request and previous to entering a cache of the computing storage environment, a determination is made, for a logical extent, whether a real extent is available. Pursuant to determining the availability of the real extent, the logical extent is allocated to the real extent by updating system metadata associated with the logical extent.

    摘要： Methods, systems, and computer storage mediums including a computer program product method for formatting storage volumes are provided. One method includes creating a storage volume including a global counter and partitioned into multiple storage segments including a segment counter and partitioned into multiple stripes, wherein the global counter and each segment counter match at an initial time. The method further includes releasing the storage segments prior to completely reformatting the storage volume and subsequently incrementing the global counter such that the global counter and each segment counter no longer match at a subsequent time. The method further includes enabling a user to write data to the storage segments prior to completely reformatting the storage volume in response to incrementing the global counter. One system includes a processor for performing the above method and one computer storage medium includes a computer program product configured to perform the above method.

    摘要： Systems and methods for initializing a memory system are provided. One system includes a processor and a memory including a storage volume coupled to the processor. The storage volume includes a first bitmap for tracking an initialization process for the storage volume and a second bitmap for tracking a copying process for the storage volume. A method includes performing, via the processor, an initialization process for the storage volume and tracking, via the processor utilizing the first bitmap, the initialization process. The method further includes performing, via the processor, a copying process for the storage volume prior to completing the initialization process and tracking, via the processor utilizing the second bitmap, the copying process. Also provided are computer storage mediums including computer program code for performing the above method.

The system further includes a processor configured to perform the below method and/or execute the below computer program product. One method includes mapping a first virtual memory address to a real memory in a memory device and mapping a second virtual memory address to the real memory. Here, the first virtual memory address is authorized to modify data in the real memory and the second virtual memory address is not authorized to modify the data in the real memory. One computer storage medium includes a computer program product for performing the above method.
