摘要： An I/O device obtains multiple unique N_Port IDs (identifiers) for a NPIV N_Port ID Virtualization (NPIV) capable physical adapter. Fabric management routines are able to assign the multiple unique N_Port IDs to distinct fabric zones. LUNs (logical unit numbers) are able to be associated with the multiple unique N_Port IDs such the LUNs associated with unique N_Port ID do not exceed a limitation. The I/O device is able to associate different resources with different unique N_Port IDs to limit the scope of actions of one or more hosts. The I/O device is able to configure one or more LUNs by the multiple unique N_Port IDs to control access. Different unique N_Port IDs are able to be configured to have different quality of service attributes and/or different levels of security. The I/O device may include multiple independent logical partitions (LPARs) and assign each multiple unique N_Port IDs.

摘要： Provided are a computer program product, system, and method for processing a read operation for a target block of data. A read operation for the target block of data in target storage is received, wherein the target block of data is in an instant virtual copy relationship with a source block of data in source storage. It is determined that the target block of data in the target storage is not consistent with the source block of data in the source storage. The source block of data is retrieved. The data in the source block of data in the cache is synthesized to make the data appear to be retrieved from the target storage. The target block of data is marked as read from the source storage. In response to the read operation completing, the target block of data that was read from the source storage is demoted.

摘要： Provided a computer program product, system, and method for cache management of tracks in a first cache and a second cache for a storage. The first cache maintains modified and unmodified tracks in the storage subject to Input/Output (I/O) requests. Modified and unmodified tracks are demoted from the first cache. The modified and the unmodified tracks demoted from the first cache are promoted to the second cache. The unmodified tracks demoted from the second cache are discarded. The modified tracks in the second cache that are at proximate physical locations on the storage device are grouped and the grouped modified tracks are destaged from the second cache to the storage device.

摘要： Provided are a computer program product, system, and method for using an attribute of a write request to determine where to cache data in a storage system having multiple caches including non-volatile storage cache in a sequential access storage device. Received modified tracks are cached in the non-volatile storage device integrated with the sequential access storage device in response to determining to cache the modified tracks. A write request having modified tracks is received. A determination is made as to whether an attribute of the received write request satisfies a condition. The received modified tracks for the write request are cached in the non-volatile storage device in response to determining that the determined attribute does not satisfy the condition. A destage request is added to a request queue for the received write request having the determined attribute not satisfying the condition.

摘要： For movement of partial data segments within a computing storage environment having lower and higher levels of cache by a processor, a whole data segment containing one of the partial data segments is promoted to both the lower and higher levels of cache. Requested data of the whole data segment is split and positioned at a Most Recently Used (MRU) portion of a demotion queue of the higher level of cache. Unrequested data of the whole data segment is split and positioned at a Least Recently Used (LRU) portion of the demotion queue of the higher level of cache. The unrequested data is pinned in place until a write of the whole data segment to the lower level of cache completes.

摘要： A method for allocating resources of a storage system including at least a first and second group of storage devices. The method identifies a first set of resources to be reserved for use by the first group of storage devices, identifies a second set of resources to be reserved for use by the second group of storage devices, and identifies a third set of resources The method then allocates resources from the third set of resources to the first group of storage devices or the second group of storage device according to an allocation algorithm, and restricts use of the first set of resources to the first group of devices and use of the second set of resources to the second group of devices.

摘要： An article of manufacture, apparatus, and a method for facilitating input/output (I/O) processing for an I/O operation at a host computer system configured for communication with a control unit. The method includes the host computer system obtaining a transport command word (TCW) for an I/O operation having both input and output data. The TCW specifies a location of the output data and a location for storing the input data. The host computer system forwards the I/O operation to the control unit for execution. The host computer system gathers the output data responsive to the location of the output data specified by the TCW, and then forwards the output data to the control unit for use in the execution of the I/O operation. The host computer system receives the input data from the control unit and stores the input data at the location specified by the TCW.

摘要： Various embodiments for storage initialization and data destage in a computing storage environment are provided. At least a portion of data on a storage device is initialized using a background process, while one of simultaneously and subsequently destaging the at least the portion of the data to the storage device using a foreground process is performed. A persistent metadata bitmap, adapted to indicate whether the at least the portion of the data has been initialized, is staged to cache, the cache operable in the computing storage environment. The background process maintains a volatile bitmap indicating a status of the initialization of the at least the portion of the data in direct correspondence to the metadata bitmap. As the background process initializes the at least the portion of the data, an applicable bit on the persistent metadata bitmap is cleared and a corresponding bit is set on the volatile bitmap.
