摘要： 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.

摘要： A method of dynamically adjusting the number of task requests is provided, which is applicable to an Internet Small Computer System Interface (iSCSI) protocol. When a target receives a task request transmitted by an initiator or the target completes the task request, the number of transmissible tasks is calculated according to an average access data volume, an current access data volume, and an allowable access data volume in the target, and returned to the initiator, such that the number of the task requests transmitted simultaneously by the initiator does not exceed the number of transmissible tasks, thereby achieving flow control. The allowable access data volume is obtained through interactive and dynamic adjustment between the target and the initiator.

摘要： A system architecture for implementing a virtual disk service (VDS) equipment is applicable for implementing an overall management on multiple service request objects in a VDS system. The system architecture includes a VDS interface, a subsystem management module, an object management module, a virtual disk management module, and a specific management module. The VDS interface receives a service request, and renders the service request to the subsystem management module for judging a type of the service request. The virtual disk management module generates a plurality of virtual interfaces for being invoked by the subsystem management module, so as to execute the service request of a public operation type. When the service request requires for supporting an asynchronous processing, the specific management module is further invoked to process the service request, and generates a feedback result to respond the service request via the VDS interface.

摘要： A hard disk testing method under an extensible firmware interface (EFI) is provided, which includes the following steps. A system file is backed up from the EFI of the hard disk into a storage area of a memory. The backup area of the system file is mapped as a real hard disk. A non-system file storage area is established in the memory, so as to store the non-system files of a hard disk test. Information of the system and non-system files of the hard disk test is acquired, so as to generate a system and a non-system file link table. When performing the test, the non-system files are backed up into the non-system file storage area. The system file link table and/or the non-system file link table is accessed, so as to load the system file and/or the non-system files directly from the storage area of the memory.

摘要： A method of identifying and dynamically updating storage device status at a target is applied for a storage area network (SAN) built by Linux system, for determining operating status of storage devices at a target through logic device identification numbers. First, a session is established between an initiator and the target, and allocated storage devices and corresponding logic unit numbers (LUNs) are obtained. Then, the initiator sends a CMD request packet with report LUN command to the target. Afterward, according to the LUNs in a received CMD response packet, operating status corresponding to the storage devices is determined. Thereby, timeout may be reduced by avoiding sending queries to those storage devices. When the device allocation is modified, the target may send an asynchronous message PDU to update a storage device status record at the target, so as to maintain the usability of the record.

摘要： A peripheral component interconnect (PCI) bus test system and method therefor, that is applied in a PCI test card. The PCI test card includes a static random-access-memory (SRAM). In the method, the data transaction of the PCI bus signal is disintegrated into a separate data operation, while eliminating the waveform interfering transaction. Through comparing the waveform of the data operation as separated from a PCI bus signal with the standard PCI bus waveform, the quality of the PCI bus signals can be precisely analyzed, thus realizing the hardware test of PCI bus.
