A method and system for batching commands and status information between a host computer and an adapter installed on the host computer. The method for command batching includes the host storing command pointers, each command pointer pointing to a command in an array, and providing an array pointer to the array. When a predetermined threshold of stored commands has been reached, the host can deliver a multitude of commands via the array pointer with a single bus access. A method for status batching includes transferring command statuses from the adapter to the host computer and providing a pointer to the transferred statuses. When a predetermined threshold of statuses has been reached, the adapter interrupts the host computer once to fetch the pointer and the host can then read the statuses without requiring any more bus interrupts.

A hierarchical storage system has a disc drive, a library apparatus, and a control apparatus. The library apparatus houses a magazine that houses a cartridge. The cartridge has a first tag and stores a storage medium configured to store the data. The magazine has a second tag. The library apparatus acquires through radio communications first information held by the first tag and configured to identify the cartridge and second information held by the second tag and configured to identify the magazine. The library apparatus transmits to the control apparatus the acquired first and second information. The control apparatus memorizes the first and second information, and manages a location of the data based on a data transfer status between the disc drive and the library apparatus and the first information and the second information stored in the first memory.

A reward points transfer system and process using blockchain is disclosed. Transaction account issuers may write reward transfer messages to the blockchain to initiate a transfer of reward points for a transaction account holders account to one or more rewards partners. Rewards partners may retrieve the reward transfer messages from the blockchain, and write a reward transfer response message to the blockchain to confirm receipt of the reward points transfer and to update the status of the transfer. The transaction account issuers and rewards partners may encrypt the messages and generate hashes based on the messages prior to writing to the blockchain, to ensure that the messages are not tampered with during the transfer process.

A method and apparatus for migrating one or more data sets each having one or more extents from one or more source logical devices to one or more target logical devices concurrently with interaction between the application and the data being migrated. A background operation copies each extent from the source logical device to the target logical device in a copy state. When a certain level of data has been copied, the extent is locked to assure synchronization of the data in the target logical device to the corresponding data in the source logical device. The status is changed to a mirrored state. When the extents for a data set in a source logical device or in a group of data sets have been mirrored, all the extents are changed to a diverted state. I/O requests to the diverted extents thereafter are intercepted and processed according to whether they access an extent that is in the copy, mirrored, or diverted state.

The present invention provides a reliable and high-speed data transfer method that achieves a high transfer efficiency and a high application processing efficiency concurrently and a disk control unit (disk controller) using such a method. In reliable data transfer in which, when data is transferred from an initiator to a target, the data received by the target is checked for validity by using an error check code attached to the data, a transfer status indicating whether the data is valid is returned from the target to the initiator, and, if a transfer error occurring during the data transfer is detected by the transfer status, the initiator retries to transfer the data to the target, a data transfer method for logical records that are units of data transfer between the initiator and the target is disclosed. This method is characterized in that: when each logical record transferred by a transfer request issued by the initiator arrives correctly on the target, the target posts a completion status corresponding to the transfer request for the logical record to a completion queue existing in the target; a plurality of logical records in a block are batch transferred; the initiator confirms the transfer status at every batch transfer; and, for each logical record that meets a predetermined batch transfer condition, the target posts a completion status corresponding to the transfer request for the logical record to the completion queue existing in the target upon correct reception of the logical record.

When the processor services the interrupt, the processor performs an internal read of the status register to determine which peripheral device requires processing. No time-consuming polling of peripheral devices is required to determine the status of the peripheral devices.

One embodiment of the present invention provides a method that maintains status information for several peripheral devices in a status register, which is located within a core logic unit in the computer system. In this embodiment, a peripheral device updates the status register if its status changes by performing a bus master operation to transfer status information to the status register. It then generates an interrupt to indicate to a processor that it requires servicing. When the processor services the interrupt, the processor merely has to read the status register to determine which peripheral device requires processing. This is a very fast operation because the status register is internal to the core logic. No time-consuming polling of peripheral devices is required to determine the status of the peripheral devices.
