Abstract: 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.

Abstract: Zum Abrufen von Auszügen beruhend auf einer Ähnlichkeitssuche bei der Deduplizierungsverarbeitung in einem Datendeduplizierungssystem unter Verwendung einer Prozessoreinheit in einer Datenverarbeitungsumgebung werden Eingabedaten in Daten-Chunks mit fester Größe aufgeteilt. Für jeden der Daten-Chunks mit fester Größe werden Ähnlichkeitselemente und Auszugsblockbegrenzungen und Auszugswerte berechnet. In einer die Ähnlichkeitselemente für jeden der Daten-Chunks mit fester Größe in einem Daten-Repository enthaltenden Suchstruktur wird nach übereinstimmenden Ähnlichkeitselementen gesucht. Positionen ähnlicher Daten werden in dem Repository ausfindig gemacht. Die Positionen der ähnlichen Daten werden zum Ausfindigmachen von gespeicherten Auszugswerten und entsprechenden gespeicherten Auszugsblockbegrenzungen der ähnlichen Daten in dem Repository und zum Laden dieser in den Hauptspeicher verwendet. Die Auszugswerte und die entsprechenden Auszugsblockbegrenzungen der Eingabedaten werden mit den gespeicherten Auszugswerten und den entsprechenden gespeicherten Auszugsblockbegrenzungen abgeglichen, um Datenübereinstimmungen zu finden.
