Abstract:
A method for copying and transferring data by remote data memory access resulting in faster data transfer speeds is provided. The method includes determining an amount of garbage data of data information, and comparing the amount of garbage data to a threshold amount. In response to the amount of garbage data being below the threshold amount, a first portion of data that includes intended data of the data information and the garbage data is copied to a remote place. In response to the amount of garbage data exceeding threshold amount, a second portion of data that includes only the intended data is copied to the remote place by a scatter/gather input/output method of a remote data memory access protocol. The copied data is returned to a free list of the remote place.
