Systems, methods and computer program products for selective copying of track data through peer-to-peer remote copy

摘要

In one embodiment, a primary storage system, includes: logic integrated with and/or executable by at least one controller, the logic being adapted to: receive a request to establish a Peer-to-Peer Remote Copy (PPRC) relationship between a primary storage system and a secondary storage system; set a path between the primary storage system and the secondary storage system via a hardwire connection in response to receiving the request; receive a memory map; establish the PPRC relationship between the primary storage system and the secondary storage system in response to receiving the memory map; and copy, based at least in part on the memory map, one or more data tracks of a primary storage device to the secondary storage system without copying at least one other data track of the primary storage device to the secondary storage system.

主权项

1. A primary storage system, comprising:
at least one primary storage device; at least one controller; an interface for a hardwire connection that is adapted to communicate data between the primary storage system and a secondary storage system; and logic integrated with and/or executable by the at least one controller, the logic being configured to:
receive a request to establish a Peer-to-Peer Remote Copy (PPRC) relationship between the primary storage system and the secondary storage system;set the path between the primary storage system and the secondary storage system via the hardwire connection in response to receiving the request;receive a memory map;establish the PPRC relationship between the primary storage system and the secondary storage system in response to receiving the memory map; andcopy, based at least in part on the memory map, one or more data tracks of the primary storage device to the secondary storage system without copying at least one other data track of the primary storage device to the secondary storage system; and wherein the one or more data tracks of the primary storage device comprise data tracks of a first characteristic, and wherein each other portion of the primary storage device comprises one or more data tracks of a second characteristic.
