摘要： A network packet capturing method for capturing a plurality of packets from a physical layer to an application layer by a network server through a network card is described. The packet capturing method includes the following steps. Capture packets by a new application interface (NAPI); set a ring queue in a kernel; provide a hook process for capturing the packets; store the captured packets into the ring queue; and map the packets stored in the ring queue into a memory space of a corresponding application through memory mapping, thereby reducing the number of interrupts of the system and the number of replications during the packets parsing.

摘要： A method for processing data packet load balancing and a network equipment thereof, which are for balancing the load of a plurality of controllers in a network equipment. The method comprises the steps. A plurality of data packets is received. A storage queue is assigned for storing the data packets. The data packets in the storage queue are read by an allocation controller. The allocation controller assigns the data packets to different work sequences according to a work attribute of the data packets. A processing controller is commanded to perform a packet processing procedure, and at least one work queue is assigned to the processing controller for processing the data packets. After completing the packet processing procedure, the processing controller sends a completion message to a completion queue. If the allocation controller detects that the completion queue contains the completion message, the allocation controller sends the processed data packets back.

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.
