    摘要： Methods, computer-readable media, and computer systems are provided for initiating storage of data on multiple storage devices and confirming storage of the data after the data has been stored on one but not necessarily all of the devices. A storage server receives, from a client, a request to store data. In response to the request, the storage server initiates, in parallel, storage of the data on multiple storage systems. The storage server detects that the data has been stored on any one of the storage systems, such as an auxiliary system, and, in response, indicates, to the client, that the data has been stored. The storage server may flush or discard data on the auxiliary storage system upon detecting that the data has been successfully stored on a target storage system, where the data persists.

    摘要： Systems, methods, and other embodiments associated with detecting a node death in a clustered distributed system are described. In one embodiment, a method includes transmitting a ping message to a peer node in the network. If a reply to the ping message is not received from the peer node, a query is sent to table of port identifiers that lists ports in the cluster. In one embodiment, the query includes a port identifier associated with the peer node. The peer node is declared as inactive/dead when the query fails to locate a match in the table for the port identifier. When the query locates a match in the table for the port identifier, another ping message is periodically transmitted to the peer node.

    摘要： A digital image capturing module assembly and method of fabricating the same is proposed, which is used for the assembly of a digital image capturing module from a photosensitive printed circuit board and a lens holder. The proposed module assembly is characterized by the use of aligning posts on the lens holder to help align and secure the photosensitive printed circuit board in position on the lens holder as well as by the use of a washer to help provide a sealed light-impenetrable effect at the junction between the photosensitive printed circuit board and the lens holder so that no sidelight can pass therethrough to the inside of the lens holder. This feature allows the assembly process to be more simplified and less time-consuming to implement than prior art, which can help increase the yield of the assembly of digital image capturing module.
