摘要： A method and computer program product for defining a multicast group within a local area network. The multicast group includes a storage initiator device, a plurality of storage targets, and one or more coded targets. A write request for storing a data segment within the multicast group is received on the storage initiator device. The data segment is multicast to the plurality of storage targets and the one or more coded targets included within the multicast group. A unique data chunk of the data segment is stored on each of the plurality of storage targets. A unique coded chunk of the data segment is generated and stored on each of the one or more coded targets.

摘要： Methods, systems, and computer program products for providing access to shared storage by a plurality of nodes are disclosed. According to one method, at a node of a plurality of nodes sharing access to a disk array, an application input/output (I/O) operation and whether sufficient space in the disk array has been mapped at the node for the I/O operation are detected. In response to detecting that sufficient space in the disk array has not been mapped at the node for the I/O operation, a map for the I/O operation including physical disk access information is requested and obtained from a server. The physical disk access information included within the map for the application I/O operation obtained from the server is used to perform the I/O operation by accessing the disk array without intervention by the server.
