Abstract: Provided are a computer program product, computer system, and method for smart selection of a storage module to be excluded when a connection between two storage modules is broken. An indication is received from a first storage module that a connection between the first storage module and a second storage module is broken. In response to determining that the second storage module is accessible, values of exclusion criteria for the first storage module are determined and summed to identify a first exclusion total. Then, values of exclusion criteria for the second storage module are determined and summed to identify a second exclusion total. In response to determining that the first exclusion total exceeds the second exclusion total, the second storage node is excluded from the cluster. In response to determining that the second exclusion total exceeds the first exclusion total, the first storage node is excluded from the cluster.

Abstract: Methods, computing systems and computer program products implement embodiments of the present invention that include configuring multiple servers coupled to a network as a software defined storage (SDS) grid. A first given server receives, via the network, an input/output (I/O) request from a host computer, and determines a location of data associated with the I/O request. In some embodiments, each of the servers maintains a local grid data map that store locations for all data managed by the SDS grid. Upon identifying, in its respective local grid data map, that a second given server is configured to process the I/O request, the first given server forwards the I/O request to the second given server for processing, and upon receiving a result of the I/O request from the second given server, the first given server conveys the result of the I/O request to the host computer.
