A method includes creating a table with a plurality of cells indicative of intersections of tracks and wedges on a data storage disc surface. The method also includes storing disc pending command information for different disc pending commands in corresponding different cells of the plurality of cells according to locations for the different disc pending commands on the data storage disc surface. The method further includes searching the table for one or more next disc pending commands of the different disc pending commands to schedule for execution.

Embodiments of the present invention disclose a data processing solution. In this solution, a hard disk receives a call instruction sent by a server, where the call instruction includes a function identifier of a to-be-called function and an operation address; and the hard disk calls the function in the hard disk based on the function identifier, and performs, based on the function, an operation on data corresponding to the operation address.

A computer-implemented method is presented for reducing data loading overhead of middleware to facilitate direct data loading to a database management system (DBMS). The method includes, while data loading, sending external-writes to a memory-based DBMS if corresponding internal-writes are for vertices, exporting all the external-writes to a disk-based DBMS as an export file, and sending an external-read for vertices to an in-memory DBMS if the middleware requests data. The method further includes, at the end of data loading, generating files for raw data of the disk-based DBMS from the export file and sending the generated raw files to the disk-based DBMS.

In accordance with one implementation, a method for adaptive in-field recalibration includes detecting a potential environmental disturbance for a first storage node in a mass storage system based on an indicator external to the first storage node, and initiating a recalibration of an operational parameter of the first storage node responsive to the detection.

A method for controlling access to data storage based on application rights dictating usage ability of a user includes: receiving, by a first application of a computing device, a data access request from a second application of the computing device, the data access request including a user identifier, namespace identifier, application identifier associated with the second application, and data command; verifying data access authorization for a user of the second application and for the second application program based on a first permission stored in an application-application rights table associated with the user identifier, application identifier, the data command; verifying data access authorization for the first application based on a second permission stored in an application-storage rights table associated with the namespace identifier and data command; executing the data command to read from or write data to a data storage interfaced with the computing device associated with the namespace identifier.

A computer-implemented method according to one embodiment includes obtaining, by a first LPAR, first device information about devices that a first LPAR is physically connected to. The first device information is sent by the first LPAR to a storage device for storage therein. Second device information stored on the storage device by a second LPAR is accessed by the first LPAR. The second device information includes information about devices that the second LPAR is physically connected to. The method further includes performing, by the first LPAR, a function using the second device information. A computer program product for device information sharing between a plurality of LPARs according to another embodiment includes a computer readable storage medium having program instructions embodied therewith. The program are instructions readable and/or executable by a first LPAR to cause the first LPAR to perform the foregoing method.

A data storage device 100 comprising: a non-volatile storage medium 108 configured to store user data 109; a data port 106 configured to transmit data and power between a host computer system 130 and the data storage device 100; a data access state indicator 140; and a controller 110 configured to: selectively set a data access state of the data storage device 100 to either: an unlocked state to enable access to the user data 109; or a locked state to disable access to the user data 109; and generate an indicator control signal to cause the data access state indicator 140 to indicate the data access state, wherein the data access state indicator 140 is configured to indicate the data access state irrespective of whether the data storage device 100 is powered through the data port 106.

Methods, systems, and devices for techniques for four cycle access commands are described. A memory device may communicate access commands with a host device over a command-address (CA) channel associated with multiple data channels. The host device may transmit an access command that includes an operation code indicating a type of the access command, a first address of the memory device that is a first target of the access command, and a second address of the memory device that is a second target of the access command. The first address may be associated with a first data channel, and the second address may be associated with a second data channel. Accordingly, the memory device and the host device may communicate first data corresponding to the first address over the first data channel and second data corresponding to the second address over the second data channel.

A method for deleting data accumulated during Automated Optical Inspection (AOI) used during an AI process uses and applies three systems. The first system obtains an image of a current object under test and writes the image of the current object under test into a current file folder on a hard disk. The current file folder includes information of point-in-time storage. The second system performs AOI on the images of objects under test. If a space available on the hard disk at any time is less than a preset value, the third system deletes file folders that have earliest storage times from the file folders stored in the hard disk. A device and a non-transitory storage medium are also disclosed.

In a method for compressing data, a storage system determines whether deduplication can be performed on a target data block. When deduplication cannot be performed on the target data block, the storage system obtaining a similar fingerprint of the target data block, and determines, based on the similar fingerprint, a combined data block group to which the target data block belongs. The storage system then performs similar compression on the target data block based on a reference block in the combined data block group.
