A method of allocating a physical memory in a specified address range under a Linux system platform is applied in a testing process of a physical memory under a Linux operating system. In this method, according to a specified address range and a size of a memory to be allocated, a large amount of physical memories in the system are allocated in a specified address range, and then the information about the allocated memories is transmitted, so as to map, inspect, and release the memories, thereby effectively supporting the test for physical memories under the Linux operating system.

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.

An internal tracing method for network attack detection is used to trace whole life cycle of an attack data packet for test in different phases such as an attacking phase, a defending phase, and an attacked phase through configuring and uniting three parties including an attack end point (AEP), a detect end point (DEP), and a target end point (TEP) and setting a corresponding internal check point in each part when testing a network intrusion detection system (IDS). In other words, when testing the network IDS, in a whole period that the attack data packet for test is attacking, filtered, detected, and finally transmitted to a target host, a tester may clearly know the statuses and information of the data packet in each important phase, thereby generating a test report conveniently, quickly, and accurately.

A data transmission system and method and a method of selecting a communication path for a dual-controller system are provided, which are applied in a first controller and a second controller of the dual-controller system. First of all, a corresponding transmission medium is selected according to a feature of a data request issued by a controller, then the data request is converted into a data format compatible with a medium interface corresponding to the selected transmission medium and is sent to a corresponding medium driving portion connected with the medium interface, and the data request is sent to another controller through the medium driving portion and a connected corresponding medium controller, so as to select a path of the highest transmission performance, and realize the data transmission between the two controllers.

A method for improving an access efficiency of a small computer system interface (SCSI) storage device is used to process a plurality of access requests for a physical storage device from a request end. The task processing method includes setting a task queue in each virtual disk, for receiving a plurality of disk access tasks sent from a server; writing the disk access tasks to storage addresses in the virtual disk; executing a storage address recording, for recording the disk access tasks having the same storage address, and sending the rest disk access tasks in sequence to the physical storage device; saving the disk access tasks into a request queue of the physical storage device; executing a program sequence optimization on the disk access tasks in the request queue; and sending back the disk access tasks after the program optimization process to the virtual disk.

A method of processing an external service request in a storage area network (SAN) is used for responding a service request in the SAN with multiple controllers, and the method includes the following steps. A first controller of the SAN receives a request packet of an external network. When the first controller determines that the request packet must be transmitted to a second controller actually providing service in an internal network, the request packet is transmitted to the second controller. The second controller receives the request packet, and parses a source address contained therein for recording. The second controller executes an operation instruction corresponding to the request packet, and then generates an acknowledge packet. The second controller takes the source address as a destination address of the acknowledge packet and directly transmits the acknowledge packet to an original request initiator.

A data transmission and writing method using multicast data flows is used for performing data transmission and writing operation of a mirror file on one or more client computers simultaneously by multicast data flows sent from various servers, in a network system architecture having a plurality of client computers and servers. Firstly, the client computer sends a request information to each server in the network by using a broadcast protocol, then the client computer is added into a plurality of multicast data flows sent by a plurality of corresponding servers according to response of each server. The data of different designated parts of the mirror file required to be downloaded is received, and the received data is finally written into a disk of the client computer. This method effectively improves data transmission amount through multicast technique of network and by fully utilizing hardware performance of the client computers.

A data management method for logical volume manager (LVM), called LVM includes a first type of physical volume and a second type of physical volume. Access speed of the first type of physical volume is higher than that of the second type of physical volume. Each physical volume has a plurality of physical extents, and a data storage method includes the following steps. Obtaining access frequencies of all the physical extents in statistics; performing a data migration operation, migrating and saving data in the physical extents satisfying an access frequency threshold value in the second type of physical volume to the physical extents without any data in the first type of physical volume; and rewriting a corresponding physical extent number for the migrated data.

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.
