Abstract: A method of labeling logic number units in a storage system results in the use of the same label for related LUNs in different storage arrays. A first storage array includes a first source logical unit number LUN, the second storage array includes a first target LUN, and the first source LUN and the first target LUN are a pair of active-active LUNs. The first storage array sends an assignable-address set of selectable labels for the first source LUN to the address assignment apparatus. The second storage array sends an assignable-address set of selectable labels for the first target LUN to the address assignment apparatus. The address assignment apparatus selects a label that is in both assignable-address sets of the first source LUN and first target LUN, and assign that selected label to both LUNs. Thereafter, the address assignment apparatus sends the selected label to the first storage array and the second storage array for identifying both the first source LUN and the first target LUN.

Abstract: A host and a storage system communicate with each other by using a NVMeoF protocol are provided. In some embodiments, the host accesses a logical disk of the host by using a control node in the storage system, and sends a state query command to the control node. The state query command is configured to instruct the control node to report a path state of a path corresponding to the control node. Still in those embodiments, the host receives the path state reported by the control node. When the received path state indicates that the logical disk includes an access interval, the host sends an interval query command to the control node; receives access interval information reported by the control node; and records a mapping relationship between the control node and the access interval information.

Abstract: A data processing method and apparatus, a server, and a controller, where the method includes receiving, by a server, a data processing request, where the data processing request includes a request sequence number, and the request sequence number marks the data processing request, generating at least one input/output (I/O) request according to the data processing request, adding the request sequence number to each of the at least one I/O request, merging the I/O requests having the request sequence number, and generating an aggregation instruction when a quantity of I/O requests having the request sequence number is greater than a preset threshold, and sending the aggregation instruction to a controller of a storage system. Hence, a time taken to perform monitoring and management using a transaction mechanism can be reduced, thereby simplifying the transaction mechanism.
