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.

摘要： A test system using a local loop to establish connection to baseboard management control is provided. The test system includes more than one host terminals having at least one network interface card (NIC) and at least one baseboard management controller (BMC) having one NIC. After establishing a connection for test between the host terminals and a remote subscriber, a connection for loop test is established with the BMC through a virtual address, so as to deliver a test instruction to the BMC for testing and to loop back a test result. The test system establishes the connection for loop test through the virtual address so as to perform a remote platform test similar to an inner loop test. Therefore, the test result will not be influenced by a network environment setting, and thus a batch test can be adopted to save the test time.

摘要： A system of protecting data in write-back cache between storage systems and the method thereof are employed to protect data in the write-back cache between a first storage system and a second storage system. The system adds, updates, or deletes the data in the second storage system backed up from the write-back cache of the first storage system by monitoring operations on the write-back cache of the first storage system and sending a corresponding command to the second storage system in accord with the monitored operation. Therefore, the method ensures the consistency between the backup data and the data stored in the write-back cache of the first storage system, thereby increasing the security of the data.

摘要： A system and method for regulating real-time the heartbeat frequency of the host according to the user-requested frequency, wherein the heartbeat frequency of the host is regulated through the service request signal sent from the user's end to the host by making use of a cluster system comprising a host and a backup host. Firstly, a frequency correspondence table is established. The host and the backup host transmit signals to each other at a predetermined frequency, which is set to the most recent heartbeat frequency of the host. Then the transmitting times of a plurality of service request signals are recorded to calculate the frequency of the most recent service request signal. Finally, the most recent heartbeat frequency of the host and the frequency of the most recent service request signal are compared to determine if the heartbeat frequency of the host needs to be regulated.

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.
