The present disclosure provides a method, device, equipment, and storage medium for aircraft tooling modification. The method includes generating, based on a modified design plan of a target aircraft, a tooling change order and a modified manufacturing bill of materials, performing, based on an initial design plan for the target aircraft, a tooling design for the tooling to obtain a design model; obtaining, based on the design model and a structural relationship of the tooling, a tooling bill of materials; modifying, based on the tooling change order, the tooling bill of materials to obtain a modified tooling bill of materials; establishing an association relationship between the modified manufacturing bill of materials and the modified tooling bill of materials; generating, based on the association relationship and the modified tooling bill of materials, a fabrication outline, and obtaining a modified tooling based on the fabrication outline.

Method, device, equipment, and storage medium for aircraft tooling modification

Embodiments of the present application disclose a traffic data self-recovery processing method, including: monitoring an operation result of traffic data synchronization operation of a target system; repeatedly performing the traffic data synchronization operation of the target system until the traffic data synchronization is successful or cumulative number of traffic data synchronization failures exceed a failure frequency threshold, if the monitored operation result is that the traffic data synchronization is failed; clearing the cumulative number if the monitored operation result is that the traffic data synchronization is successful; stopping the traffic data synchronization operation of the target system and sending out a message indicative of the traffic data synchronization failure if the cumulative number of traffic data synchronization failures exceeds the failure frequency threshold, wherein the failure frequency threshold is determined by current network signal intensity of the target system and is in a positive correlation with current network signal intensity.

Traffic data self-recovery processing method, readable storage medium, server and apparatus

A method for writing multiple copies into a storage device includes receiving a first write data request that includes an identity (ID) of a first logical storage unit, target data, and a logical block address (LBA) of the first logical storage unit, determining that data stored in storage space corresponding to the LBA of the first logical storage unit is not accessed by another data access request, writing the target data into the storage space corresponding to the LBA of the first logical storage unit, generating a second write data request that includes an ID of a second logical storage unit, the target data, and an LBA of the second logical storage unit, and writing the target data into storage space corresponding to the LBA of the second logical storage unit.

Method for writing multiple copies into storage device, and storage device

A snapshot processing method includes: receiving a snapshot request command, where the snapshot request command includes an ID of a primary LUN; determining the primary LUN according to the ID of the primary LUN, and setting a snapshot status of the primary LUN to a preparation state; sending a first snapshot command to a mirror storage device, where the first snapshot command includes the ID of the primary LUN, and the first snapshot command is used to notify the mirror storage device that the primary LUN is in the preparation state; receiving a response message, sent by the mirror storage device, of the first snapshot command, where the response message is used to notify the primary storage device that a mirrored LUN is in the preparation state; and performing snapshot processing on the primary LUN.

Snapshot processing method and related device

The embodiments of the present invention provide a data storage method, including: sending a performance level request to a storage device, which is used to query information about performance level of one or more logical unit number LUNs in the storage device; receiving a response sent by the storage device in response to the performance level request, wherein the response comprises the information about performance levels of the LUNs; and obtaining performance levels of the LUNs according to the information about performance levels of the LUNs so that data to be stored is written into a LUN of a corresponding performance level according to a accessing frequency level of the data to be stored comprised in a write-data instruction when the write-data instruction is received.

Data storage method and storage device

A method for backing up data of a storage system, where at least two mirroring channels are provided between a first mainboard and a second mainboard of a storage system, and the method includes: transmitting data through at least one effective mirroring channel if all the mirroring channels are effective; and transmitting the data through remaining mirroring channel(s) if at least one of the mirroring channels for transmitting the data fails. The method enables traffic to be transmitted evenly on normal mirroring channels, and ensures maximized utilization of the bandwidth of mirroring channels.
