摘要： According to an embodiment there is provided a method for handling requests in a storage system including a plurality of storage nodes connected to each other via a communications network. A first storage node of the plurality of storage nodes may store a reference to a set of at least one collection object stored in the storage system. Each collection object of the set may include at least one of a reference to another collection object stored in the storage system and a reference to at least one data file stored in the storage system. The method may include receiving a first request at the first storage node. The first storage node, for each collection object of the set, may send a second request to a storage node storing the collection object. According to a second aspect there is also provided a storage node.

摘要： The present invention relates to a distributed data storage system comprising a plurality of storage nodes. Using unicast and multicast transmission, a server application may write data in the storage system. When writing data, at least two storage nodes are selected based in part on a randomized function, which ensures that data is sufficiently spread to provide efficient and reliable replication of data in case a storage node malfunctions.

摘要： The present invention relates to a distributed data storage system comprising a plurality of storage nodes. Using unicast and multicast transmission, a server application may read and write data in the storage system. Each storage node may monitor reading and writing operations on the system as well as the status of other storage nodes. In this way, the storage nodes may detect a need for replication of files on the system, and may carry out a replication process that serves to maintain a storage of a sufficient number of copies of files with correct versions at geographically diverse locations.

摘要： A holder for at least one eyepiece is described. The holder includes an upper plate having at least two upper apertures therethrough, a top surface, and a bottom surface, and a lower plate having at least two lower apertures therethrough, a top surface, and a bottom surface. Each lower aperture corresponds to one of the upper apertures of the upper plate. When the upper and lower plates are mutually aligned, the at least one eyepiece may be inserted through corresponding upper and lower apertures. Furthermore, when one of the plates is selectively slid with respect to the other plate, the upper and lower apertures become misaligned to bind the at least one eyepiece to retain the eyepiece in the holder.

摘要： A method for maintaining a data storage system is disclosed. The method may include monitoring a first data storage node. The method may also include detecting a condition regarding the first data storage node, and the condition may indicate that at least one file stored on the first data storage node is to be replicated. The method may also include updating a replication list based on detecting the condition, and the replication list may include an identification of the at least one file and priority information for replication of the at least one file. The method may include performing a data replication procedure based on the replication list, where the data replication procedure may include sending a first multicast message to a plurality of other data storage nodes requesting identification of a second data storage node that maintains a copy of the at least one file.

摘要： A method for maintaining a data storage system is disclosed. The method may include monitoring for receipt of a first broadcast message from a first data storage node, where the first broadcast message may indicate that the first data storage node is operating correctly. The method may also include detecting that the first data storage node is malfunctioning based on not receiving the first broadcast message for a predetermined period of time. The method may also include initiating a data replication procedure based on detecting that the first data storage node is malfunctioning. The data replication procedure may include sending a first multicast message to a plurality of data storage nodes requesting identification of a second data storage node that maintains a copy of a file stored on the first data storage node.
