Techniques for transferring files between machines include creating a zero-length target file on non-volatile storage, truncating the file to a desired size, and allocating storage on the non-volatile storage for each block of the target file. The technique also includes determining a logical block address (LBA) for each location in the target file. The technique further includes sending a request to an input/output (I/O) node to transfer a source file to the non-volatile storage, where the request includes a mapping between the LBAs and file offsets. The technique includes opening the source file and a block device at the I/O node. The technique further includes reading each block from the source file and writing each block to the target file on the non-volatile storage utilizing the block device, and then closing the source file and the block device.
