摘要： A method of adjusting a network data sending speed according to a data processing speed at a client is described. Through calculating and feeding back a data processing speed of a client computer to a server; and then, controlling and adjusting a data sending speed at the server in real time according to the data processing speed, the server adjusts the data sending speed thereof in real time according to the requirement on speed control, and sends data to the client computer at an adjusted data sending speed. This method controls and adjusts the data sending speed at the server through a feedback mechanism of the data processing speed of the client computer, thereby avoiding problems in the conventional art, such as low network data transmission efficiency and data loss, caused by mismatching between the data processing speed at the client and the data sending speed at the server.

摘要： An alarm display system of a cluster storage system and a method thereof are described. A reasonable single abnormal event processing manner is adopted to classify the alarm priority through abnormal events detected by different nodes sharing a common device in the cluster storage system, and analyze load of each node. That is, nodes with lower loads are analyzed to obtain all the abnormal events of the common device and the node most affected by the abnormal events in the cluster storage system. Afterward, the analysis result is transmitted to each node, and each node then informs a subscriber with an alarm prompt, so as to reasonably and correctly alarm the subscriber with abnormal events of the common device and impacts thereof on the nodes.

摘要： A data backup method for logical volume manager (LVM) is used for backup the original data in the LV when adding newly data into a logical volume of the LVM. Before adding a snapshot volume, a new storage space is created. The LVM writes the data to be altered in the logical volume into the new storage space. The LVM then renames the logical volume to the snapshot volume, and names the new storage space to the logical volume. According to the method, reading and writing times of the physical disk can be reduced, so as to quicken backup efficiency.

摘要： A method for skipping an initialization process of synchronization of an RAID 1 device skips synchronization process of the RAID1 device through a bitmap technique. First, an RAID1 device is established, a space of the same size is divided from each member disk of the RAID1 device for storing a bitmap corresponding to each data block on each member disk. When a read/write operation is executed on the RAID1 device, before the bit value in the bitmap corresponding to the data block is read, whether the bitmap exists or not is determined first, then corresponding operation is executed according to the bit value in the bitmap corresponding to data block requesting the read/write operation. The method skips synchronization process of the RAID 1 device during the initial establishment, thereby largely saving the time required by the synchronization process for initialization, and further improving the overall performance of the RAID1 device.

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.
