US 11,635,897 B2 · System and method for efficient implementation of XCopy commands

Abstract

A method, computer program product, and computer system for receiving an XCopy command is provided. The XCopy command may be in the form of an IO operation. The IO operation may be a subextent block operation. A source range and a destination range of the XCopy command may be determined to be aligned within an alignment boundary. The Xcopy command may be determined to be smaller than a predetermined size. In response to determining the source range and destination range of the XCopy command are aligned within the alignment boundary and the XCopy command is smaller than a predetermined size, the XCopy command may be processed. The receiving of the XCopy command may be recorded in a log.

Dependent claims

A computer-implemented method comprising:

receiving, via a computing device, an XCopy command, wherein the XCopy command is in the form of an IO operation, wherein the IO operation is a subextent block operation;
determining if a source range and a destination range of the XCopy command are aligned within an alignment boundary and the XCopy command is smaller than a predetermined size;
in response to determining the source range and destination range of the XCopy command are aligned within the alignment boundary and the XCopy command is smaller than a predetermined size, processing the XCopy command;
and
recording, in a log, that the XCopy command was received.
