摘要： A mass storage system has a host computer connecting over a standard bus to a storage controller. The storage controller connects also to an array of disk drives. The host computer and the storage controller modify standard bus diagnostic commands for transmitting selected, non-diagnostic commands, and responses to each other. In this manner, a standard bus protocol is expanded to enable a host computer and storage controller to communicate, for example, configuration data, status, and some command information, particularly enabling the user at the host computer to control operational aspects of the storage controller.

摘要： A digital data storage subsystem stores data for use by digital data utilization device. The data as used by the digital data utilization device being organized in the form of variable-length records. The digital data storage subsystem includes a digital data storage device, a cache and a cache control. The digital data storage device has at least one fixed block storage unit for storing a predetermined amount of data, the storage unit storing at least one record and additional padding if the record does not comprise at least said predetermined amount of data. The cache including at least one cache slot which can accommodate the storage of the predetermined amount of data, that is, the amount which can be stored on the block storage unit of the digital data storage device. The cache control controls the transfer of data from the fixed block storage unit to the cache slot for use by the digital data utilization device, and in addition controls the transfer of data from the cache slot to the fixed block storage unit if the digital data utilization device modifies the data in the cache slot. The cache control controls the transfer so that the format of the data in the fixed block storage unit conforms to the format of the data in the cache slot, so that no changes are required to the formatting of the data during such a transfer.

摘要： Accessing stored data includes providing a virtual storage area having a table of pointers that point to sections of at least two other storage areas, where the virtual storage area contains no sections of data, in response to a request for accessing data of the virtual storage area, determining which particular one of the other storage areas contain the data, and accessing the data on the particular one of the other storage areas using the table of pointers. Accessing stored data may also include associating a first one of the other storage areas with the virtual storage area, where the virtual area device represents a copy of data of the first one of the other storage areas. Accessing stored data may also include causing all of the pointers of the table to initially point to sections of the first one of the other storage areas when the virtual storage area is initially associated with the first one of the other storage areas. The storage areas may be storage devices. The sections may be tracks.

摘要： A method, system, and computer program product are disclosed for managing data in a cache. A first cache memory is provided that includes data. A second cache memory is provided that also includes data in which at least some of the data in the first cache memory is the same as at least some of the data in the second cache memory. In response to a request for data that is stored in both the first and second cache memories, one of the cache memories is chosen in accordance with an access balancing technique. The access balancing technique may include at least one of selection using round robin, and selection based on statistical analysis such as access frequency of the first and second cache memories. First and second access balancing techniques may be used for data accessed from the cache memories, which may comprise disk data and control data, such as data indicating whether data in the caches has been modified and is write pending.

摘要： A method for enabling overlapped input/output requests to a logical device using assigned and parallel access unit control blocks. Each I/O request interrupts an operating system to assign a base and related unit control block to the input/output requests. In addition a parallel access control block is associated with each unit control block for a logical volume and a parallel access main control block is established with a logical volume through which each of the base and related unit control block can be identified. An input/output request to a logical device interrupts the operating system to assign one of the base and one of the assigned unit control blocks to the input/output requests after which control transfers back to the operating system. At a disk storage facility, the input/output request is located in a table with other input/output requests and corresponding parameters. The disk array storage facility tests the parameters for each new input/output request to determine which of a plurality of control functions will be performed.
