TECHNIQUES FOR MAINTAINING COMMUNICATIONS SESSIONS AMONG NODES IN A STORAGE CLUSTER SYSTEM

摘要

Various embodiments are generally directed to techniques for preparing to respond to failures in performing a data access command to modify client device data in a storage cluster system. An apparatus may include a processor component of a first node coupled to a first storage device; an access component to perform a command on the first storage device; a replication component to exchange a replica of the command with the second node via a communications session formed between the first and second nodes to enable at least a partially parallel performance of the command by the first and second nodes; and a multipath component to change a state of the communications session from inactive to active to enable the exchange of the replica based on an indication of a failure within a third node that precludes performance of the command by the third node. Other embodiments are described and claimed.

主权项

1. An apparatus comprising:
a processor component of a first node, the first node coupled to a first storage device storing client device data; an access component for execution by the processor component to perform a command on the first storage device, the command comprising a data access command to alter the client device data stored in the first storage device and in a second storage device couple to a second node; a replication component for execution by the processor component to exchange a replica of the command with the second node via a communications session formed between the first and second nodes to enable at least a partially parallel performance of the command by the first and second nodes; and a multipath component for execution by the processor component to change a state of the communications session from inactive to active to enable the exchange of the replica through the communication session based on an indication of a failure within a third node coupled to the first node that precludes performance of the command by the third node.
