Abstract: Various embodiments are generally directed to techniques for handling errors affecting the at least partially parallel performance of data access commands between nodes of a storage cluster system. An apparatus may include a processor component of a first node, an access component to perform a command received from a client device via a network to alter client device data stored in a first storage device coupled to the first node, a replication component to transmit a replica of the command to a second node via the network to enable performance of the replica by the second node at least partially in parallel, an error component to retry transmission of the replica based on a failure indicated by the second node and a status component to select a status indication to transmit to the client device based on the indication of failure and results of retrial of transmission of the replica.

Abstract: Various embodiments are directed to techniques for coordinating at least partially parallel performance and cancellation of data access commands between nodes of a storage cluster system. An apparatus may include a processor component of a first node coupled to a first storage device storing client device data; an access component to perform replica data access commands of replica command sets on the client device data, each replica command set assigned a set ID; a communications component to analyze a set ID included in a network packet to determine whether a portion of a replica command set in the network packet is redundant, and to reassemble the replica command set from the portion based if the portion is not redundant; and an ordering component to provide the communications component with set IDs of replica command sets of which the access component has fully performed the set of replica data access commands.
