摘要： A position detecting system and method for an electronic device used an audio signal input module of the electronic device and a signal receiver to connect to the audio signal input module convert an external position signal into an audio signal. A position detecting software running on the electronic device analyzes the audio signal. Accordingly, the current position of the electronic device is obtained. The audio signal input module of the electronic device is employed as an input port for the external position signal, thus saving the construction cost of the system. Besides, the current position of the electronic device with an ever-changing position can be obtained during a test process, such that the electronic device can start or stop a test item accordingly.

摘要： A virtual disk (VD) router system, a VD access system, and a method therefor, applied to a dual-controller system including a first controller and a second controller, are provided. First, a mapping virtual block device (VBD) corresponding to a VD of the second controller and/or the first controller is established in the first controller and/or the second controller, and a mapping relation list and a data transmission channel of the VD and the corresponding VBD thereof are established. When the first controller/the second controller issues an access request to the VD of the second controller/the first controller, the data transmission channel is used to transmit the access request to the VD and transmit the response data to the access request from the VD. Therefore, the overall access to all the VDs in the dual-controller system can be achieved.

摘要： A file data restoring system and method of a computer operating system and software thereof are applied in the installation of an operating system into a client computer. Divide the file data corresponding to the operating system into data blocks according to an appointed data size. Generate a check code for each of the data blocks to form a sequence list of original check codes and a sequence list of target check codes. Compare the sequence list of original check codes with the sequence list of target check codes, after installing the operating system into the computer. If the comparison result is inconsistent, a restoring call information is sent out. The position of the inconsistent check code is acquired through the restoring call information and the comparison result. The original file data corresponding to the position of the check code is read and restored to a corresponding target file.

摘要： A remote replication synchronizing/accessing system and a method thereof applied between a local system and a remote mirroring system of the local system. After the remote mirroring system is created, an initialization synchronous operation of the remote mirroring system is sequentially performed according to a sequence of data blocks in storage of the local system. A small-granulated exclusive lock function is established between the initialization synchronous operation and a data-accessing request operation of the local system. During the initialization synchronous process of the remote mirroring system, it is determined whether a data block position corresponding to the current initialization synchronous operation is the same as that corresponding to the data-accessing request operation or not. Finally, according to a position determination result and the small-granulated exclusive lock function, a data-accessing request is directed processed or processed after finishing the initialization synchronous operation.

摘要： A system of creating logical volume and method thereof is used to solve the problems such as creation steps are complicated, a space of storage medium is wasted and the number of snapshots to be created is limited. An available logical volume space and a timestamp storage area are allocated in the logical volume according to space allocation algorithm. According to original data and data amended at subsequent time point in the logical volume, copy-on-write operation is sequentially performed on the amended data in the logical volume to create a timestamp corresponding to the time point. The timestamp of the corresponding time point is stored in the timestamp storage area. A storage medium offset address pointer is created to record writing position of the copy-on-write operation of the corresponding time point. And the pointer is stored in the storage medium to serve as index information of address of each timestamp.

摘要： An alarm method for insufficient storage space of a network storage system is provided. The method includes the following steps. Preset a time alarm threshold value according to a current operation state of the system when allocating storage spaces to users. Estimate a time that written data fully occupy a current remaining space according to a data writing speed to the storage space, a current idle memory of the system, total dirty data in a cache of the system, and the current remaining space in the storage space. Compare the estimated time value and the time alarm threshold value. And, send alarm information when the estimated time value is smaller than the time alarm threshold value. By setting the alarm threshold value of a time concept, a timely alarm of insufficient storage space is realized, which enhances the effective management of the storage space.
