PURPOSE: A distribution storage system considering a delay unit, a distribution storage management device, and a method are provided to exclude a storage node or a storage group which includes a unit which delays data reading/writing operation processing in a distribution storage environment, thereby rapidly processing a data reading/writing request. CONSTITUTION: A detection unit(120) detects a busy storage node. A control unit(140) delivers a data reading and writing request to the remaining storage node excluding the busy storage node. The storage node includes a non-volatile memory. The detection unit detects a storage node, which performs garbage collection, as the busy storage node. The detection unit detects a storage node, to which a request stored in a corresponding queue exceeds a predetermined threshold value, as the busy storage node. [Reference numerals] (120) Detection unit; (140) Control unit
