Abstract
An apparatus comprises at least one processing device configured, in conjunction with processing of an input-output (IO) operation by a first storage node of a distributed storage system, where processing of the IO operation requires access to at least one persistent storage device remote from the first storage node but local to a second storage node of the distributed storage system, to send a request from the first storage node to the second storage node identifying data associated with the operation. The processing device determines a buffer of the second storage node that is allocated for use by the second storage node for temporary storage of the data, and utilizes the buffer to provide the data to the second storage node to allow the second storage node to write the data, and/or to obtain the data from the second storage node after the second storage node has read the data.
