摘要：
A data storage system including at least one storage controller having a first color policy and operative to store data onto a first data storage unit at a primary site as part of a current color of the primary site, at least one storage controller having a second color policy and operative to store data onto a second data storage unit at the primary site as part of the current color, and a color control node operative to provide each of the controllers with new color information while maintaining the integrity of dependent writes across color boundaries.
