Abstract: PROBLEM TO BE SOLVED: To manage consistency groups using heterogeneous replication engines replicating data. SOLUTION: A common linkage manager issues a consistency group creation prepare command to first and second replication managers, who issue consistency group create commands to first and second replication engines. The first and second replication managers create data in first and second consistency groups which are consistent at a point in time corresponding to the consistency group create commands, and transmit them to first and second journals respectively. The first and second replication managers commit data in the first and second consistency groups of first and second journals to first and second target storages respectively in response to the first and second replication managers having received commit commands.

Abstract: PROBLEM TO BE SOLVED: To provide a method, a system, and a product for managing consistency groups using heterogeneous replication engines replicating data. SOLUTION: A common linkage manager issues a consistency group creation prepare command to a first replication manager and a second replication manager, which create consistency groups of data in a first source storage and a second source storage and issue consistency group create commands to first and second replication engines. The first and second replication managers create a first consistency group and a second consistency group of data which are consistent at a point in time corresponding to the consistency group create commands, and the first and second replication managers commit data in the first and second consistency groups of first and second journals to first and second target storages respectively.

Abstract: An apparatus, method and computer program in a distributed cluster storage network comprises storage control nodes to write data to storage on request from a host;a forwarding layer at a first node to forward data to a second node; a buffer controller at each node to allocate buffers for data to be written; and a communication link between the buffer controller and the forwarding layer at each node to communicate a constrained or unconstrained status indicator of the buffer resource to the forwarding layer. A mode selector selects a constrained mode of operation requiring allocation of buffer resource at the second node and communication of the allocation before the first node can allocate buffers and forward data, or an unconstrained mode of operation granting use of a predetermined resource credit provided by the second to the first node and permitting forwarding of a write request with data.

Abstract: Vorrichtung, Verfahren und Computerprogramm in einem verteilten Gruppenspeichernetz, wobei die Vorrichtung Folgendes umfasst: Speichersteuerknoten, um auf Anforderung von einem Host Daten in den Speicher zu schreiben; eine Weiterleitungsschicht in einem ersten Knoten zur Weiterleitung von Daten an einen zweiten Knoten; eine Puffersteuereinheit in jedem Knoten zum Zuordnen von Puffern für zu schreibende Daten; und eine Datenübertragungsverbindung zwischen der Puffersteuereinheit und der Weiterleitungsschicht in jedem Knoten, um einen Anzeiger für einen eingeschränkten oder nichteingeschränkten Status der Puffer-Ressource an die Weiterleitungsschicht zu übertragen. Eine Modusauswähleinheit wählt einen eingeschränkten Betriebsmodus, der die Zuordnung einer Puffer-Ressource im zweiten Knoten und die Übertragung der Zuordnung erfordert macht, bevor der erste Knoten Puffer zuordnen und Daten weiterleiten kann, oder einen nichteingeschränkten Betriebsmodus, der die Verwendung eines festgelegten Ressourcen-Guthabens gestattet, das vom zweiten Knoten an den ersten Knoten bereitgestellt wird und das Weiterleiten einer Schreibanforderung mit Daten gestattet.
