Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Abstract: Dynamic logical mapping (“DLM”) provides a virtual layer interposed between a host and a data storage library. Residing on the library, DLM creates a data storage map that records and manages the relationship between a storage cartridge's physical address and that cartridge's mapping to a logical address. During runtime of the data storage library, DLM manages the physical to logical address mapping of each storage cartridge so as to optimize efficiency and speed of the data storage library.

Abstract: A method and system for retrieving data that is stored on a backup or secondary storage system located at a remote location to a local storage system. Restoring of backup data involves the transferring of a point-in-time copy of primary system data from a secondary storage system to the local system. The point-in-time copy is created on the secondary system using an asynchronous remote copy scheme. The point-in-time copy that is restored may be either an entire volume or portions thereof.

Abstract: A cache storage system and method are provided for saving storage space in a cache, the system and method for use in a data storage system having multiple storage devices and multiple virtual addresses, each virtual address having a data object associated therewith. Each data object is stored at a storage device location having a unique identifier. The cache storage system and method include a cache for storing a data object associated with at least one virtual address. For a first virtual address, the first virtual address data object is staged into the cache. For a second virtual address, a pointer is generated for use in pointing to the first virtual address data object staged in the cache when the storage device location identifier of the second virtual address data object matches the storage device location identifier of the first virtual address data object.

The cache control processor receives a cache bitmap from the host computer to specify the data blocks from the mass storage device to be pre-staged into the cache memory.

Abstract: A storage system and method for storing delta difference data indicative of the differences between new data and old data. A data transferring unit has copies of old data and new data. The data transferring unit compares the new data with the old data to determine delta difference data indicative of the differences between the new data and the old data. A target storage device having a copy of the old data receives the delta difference data from the data transferring unit. The target storage device stores the delta difference data and may then determine the new data by merging the old data with the delta difference data. The target storage device transmits the determined new data to a data receiving unit upon request. The method and system may be used with peer-to-peer remote copy (PPRC) storage system and storage area network (SAN) storage system.

Abstract: Systems and methods are provided to backup, restore and relocate compressed data images, e.g., DASD compressed tracks, associated with virtual storage volumes. A compressed track image of the data is first stored in a storage volume. The data derives from a connected host connected with a control unit that manages the storage volume. When the host data is uncompressed, the control unit compresses the data. In backup, the host reads the compressed data with a read protocol and the control unit assigns metadata to the compressed track. The compressed track is then stored in a backup device, e.g., a tape drive. In restore, the host writes the compressed track to the control unit with a write protocol. If desired, the track is relocated to a different location or to a different storage volume through the associated metadata. In decompression, a seed value is assigned to the data to ensure identification across relocation.

Abstract: A system and method for synchronizing a data copy include in one embodiment first and second remote copy trios, each with source, target, and secondary volumes. Source volumes store initial data files, execute write commands to generate updated data files, and generate records of the write commands. Target volumes receive copies of the initial data files and the write command records, and transmit the copies of the initial data files and data indicated by the write command records to secondary volumes. Secondary volumes store the copies of the initial data files and the data indicated by the write command records, which are available for use in generating copies of the updated data files. The target volumes transmit to the secondary volumes in series relative to each other so that consistency is maintained at all times across the source volumes.

Abstract: A data processing system, computer program product, and data processing system for providing an adjustable level of synchronicity between duplicated transactions is disclosed. An acceptable level of lag between transactions is specified. Duplicated transactions performed at redundant systems are allowed to lag behind the corresponding transactions at the primary system by the specified amount of lag. Lag may be measured in terms of number of transactions, an amount of data, amount of time, or using any other suitable metric.

Abstract: A method and apparatus for transferring data from a first storage system to a second storage system in which the first storage system includes a first plurality of storage devices and the second storage system includes a second plurality of storage devices. Data is transferred using a pair of devices selected for transferring data for all of the storage devices. Data to be transferred from source storage devices within the first plurality of storage devices is placed or queued on a selected primary storage device within the first plurality of storage devices. The data is sent to a selected secondary storage device within the plurality of storage devices. The data is relocated from the selected secondary storage device to target storage devices within the second plurality of storage devices.

Abstract: A method and apparatus in a data processing system for copying data. A request is received to copy data from a first storage system to second storage system, wherein the request identifies a source volume on the first storage system and a target volume on the second storage system and wherein data is located on a first source volume in the first storage system. Data is transferred to a second source volume in the first storage system. A pair is automatically established between the second source volume and the target volume. The data for the request is copied from the second source volume to the target volume after the pair has been automatically established. The pair is terminated after the data has been copied to the target volume. The requester originating the request is notified of the result of the copy operation.

Abstract: A method and system for transferring data from a primary storage system to a secondary storage system in which the primary storage system includes primary storage volumes and a primary bridge volume and the secondary storage system includes secondary storage volumes and a secondary bridge volume. A link between the primary bridge volume and the secondary bridge volume is established. The data to be transferred from a primary storage volume to a corresponding secondary storage volume is then copied onto the primary bridge volume by using pointers to the data of the primary storage volume (internal snapshot copy). Snapshot copied data is then transferred from the primary bridge volume to the secondary bridge volume over the link. The data is then moved from the secondary bridge volume to the secondary storage volume corresponding to the primary storage volume to put the primary storage volume and the corresponding secondary storage volume in synchronization.
