Snapshot transmission from storage array to cloud using multi-path input-output

A method performed by a processing device configured to communicate over a network with a storage system, comprising:

• configuring a multi-path input-output driver of the processing device to control delivery of input-output operations from the processing device to a storage system over selected ones of a plurality of paths through a network;
• the paths being associated with respective initiator-target pairs wherein each of a plurality of targets of the initiator-target pairs comprises a corresponding port of the storage system;
• the multi-path input-output driver:
• creating a plurality of input-output operation threads;
• using a given input-output operation thread of the plurality of input-output operation threads to retrieve a given input-output operation from an input-output queue;
• attempting to perform the given input-output operation on a given target of the plurality of targets;
• and
• returning the given input-output operation to the input-output queue upon a failure to perform the given input-output operation;
• wherein the processing device comprises a processor coupled to a memory.

A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code, when executed by a processing device comprising a processor coupled to a memory, the processing device being configured to communicate over a network with a storage system and comprising a multi-path input-output driver, causes the multi-path input-output driver:

• to control delivery of input-output operations from the processing device to the storage system over selected ones of a plurality of paths through the network;
• the paths being associated with respective initiator-target pairs wherein each of a plurality of targets of the initiator-target pairs comprises a corresponding port of the storage system;
• to create a plurality of input-output operation threads;
• to use a given input-output operation thread of the plurality of input-output operation threads to retrieve a given input-output operation from an input-output queue;
• to attempt to perform the given input-output operation on a given target of the plurality of targets;
• and
• to return the given input-output operation to the input-output queue upon a failure to perform the given input-output operation.
