A device and a method for testing SAS channels which are applied to a plurality of pairs of SAS interfaces. The testing device includes a control terminal, a PCI-E microprocessor, a PCI-E-to-SAS adaptor, and a signal feedback module. The control terminal is used for selecting SAS channels and sending a control command; the PCI-E microprocessor is used for receiving the control command and sending a test signal to a PCI-E channel according to the control command; the PCI-E-to-SAS adaptor is used for converting a transmission signal between the PCI-E channel and the SAS channels; and the signal feedback module is used for connecting a first SAS interface to a second SAS interface in the SAS back plate. The PCI-E microprocessor compares whether the test signal sent to the first SAS channel is consistent with the test signal received from the second SAS interface.

A system and method for parallel burning using multiplex technology is used for burning chips of different bus types on the same transmission bus at the same time in parallel. A main control unit divides bandwidth of the transmission bus into different frequency bands, sends a control command including a command for sending data carrying bus signals of designated types, and controls data carrying the bus signals of the designated types to be transmitted in designated frequency bands of the transmission bus. Then, a sending unit sends the data carrying the bus signals of the designated types in the designated frequency band. Finally, receiving units receive the data transmitted in the designated frequency bands, and then output them to a plurality of burners such as to burn the data onto the chips of the designated bus types in parallel.

A system and a method of testing bridge SAS channels includes a control terminal, a hot-plug bridge interface, a first adaptor, an SAS back plate, and a second adaptor. The control terminal selects an SAS interface as a transmission path for sending a test signal. The hot-plug bridge interface receives and converts the test signal sent from the control terminal. The hot-plug bridge interface has a hot-plug function. The first adaptor is connected to the hot-plug bridge interface and the SAS back plate. The second adaptor is connected between the SAS back plate and a terminal unit. The control terminal sends the test signal and detects a signal under test sent back from the terminal unit, and compares whether they are consistent with each other or not. In this way, the control terminal determines whether the SAS interfaces in the SAS back plate run normally or not.

A system and method for updating dirty data of designated raw device is applied in Linux system. A format of a command parameter for updating the dirty data of the designated raw device is determined, to obtain the command parameter with the correct format and transmit it into the Kernel of the Linux system. Then, a data structure of the designated raw device is sought based on the command parameter, to obtain a fast search tree of the designated raw device. Finally, all dirty data pages of the designated raw device are found by the fast search tree, and then are updated into a magnetic disk in a synchronous or asynchronous manner. Therefore, the dirty data of an individual raw device can be updated and written into the magnetic disk without interrupting the normal operation of the system, hereby ensuring secure, convenient, and highly efficient update of the dirty data.

A network intrusion protection system (NIPS) is built at an important network node, for example, at a boundary router, for filtering network packets containing malicious intrusion/attacking behaviors. A network card of the NIPS includes a microprocessor, a network packet decode procedure and a malicious intrusion packet filtering procedure, for filtering malicious network packets in advance according to header information of the network packets. Then, a central processor of the NIPS is used to parse the contents in the rest network packets, and determine whether the network packets are malicious packets according to an intrusion behavior definition file. The network packets are discarded if the network packets are malicious. Otherwise, the network packets are transferred to computers in internal local area network if the network packets not malicious.

A method of generating an image file may generate corresponding image files from data units in a first storage device of a source. The method of generating an image file includes generating an image file head according to hardware parameter information of the first storage device; partitioning the first storage device into a plurality of data units with the same size; performing a compression process to compress data in the data units, respectively, thereby generating corresponding compressed data blocks; sequentially storing the compressed data blocks in a data area of the image file; creating an index table to use an index value to record start positions of the data units in the first storage device and positions of the compressed data blocks in the data area into the index table; and creating a file foot information to mark a file length of the image file.

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 method of accessing a virtual storage device through a virtual data router (VD router) is described. A virtual disk device on a controller may be accessed from various controllers through different paths based on asynchrony of data sending/receiving of a VD router. Moreover, the method is advantageous in having high access efficiency and consistency of data access via different paths at the same time.

A system and a method for rapidly diagnosing bugs of system software are apply for rapidly localizing a system program fault that causes a system error and then feeding back to a subscriber. First, according to the subscriber's requirement, a program of system fault analysis standard is preset and written into the system. Next, a plurality of fault insertion points is added into a program module of the system according to the subscriber's requirement for the precision of the fault analysis result. Then, fault management information is generated at the fault insertion points during the running process of the system program, and the management information is monitored for collecting relevant system fault data. After that, the collected system fault data is analyzed in real time through the program of system fault analysis standard, so as to obtain the minimum fault set for causing the system error.

A testing device and method of card reading interface are applied to a card reading interface including a plurality of memory cards, and are used to integrate memory card interfaces in a memory card slot. The testing device includes memory cards, a switching unit, a connecting part, and a connecting circuit. Wherein, the switching unit receives a switching instruction and selects a corresponding memory card according to the switching instruction. The connecting part is electrically connected between the memory card slot and the switching unit. The connecting circuit is connected between the switching unit and the memory cards, and transmits detection data to the laptop computer. The laptop computer checks the detection data before testing and after testing. Thus, the device and method thereof can detects function normally or not on the memory card slot, and reduces the plugging times from the memory card slot.
