  • Write set boundary management in support of asynchronous update of secondary storage
    Patent number: 8200916
    Abstract: A color control node includes an interface for communicating with multiple storage controllers, wherein the storage controllers maintain a primary storage system at a primary site and a secondary storage system at a secondary site; and wherein the storage controllers maintain a current color and associate all writes with the current color without polling the color control node. The color control node also includes operational capability for issuing a polling command to instruct the storage controllers to poll the color control node for the current color prior to associating each write with a new color; receiving an acknowledgment of receipt of the polling command; changing the current color to a new color responsive to receiving the acknowledgment; issuing a storage command to the storage controllers indicating the new color; and instructing each storage controller to cease polling the color control node for the current color.
