20080301332 | METHOD FOR USING HOST AND STORAGE CONTROLLER PORT INFORMATION TO CONFIGURE PATHS BETWEEN A HOST AND STORAGE CONTROLLER - Provided is a method for using host and storage controller port information to configure paths between a host and storage controller. Information is gathered on ports on at least one host, ports on at least one storage controller managing access to storage volumes, and at least one fabric over which the at least one host and storage controller ports connect. For at least one host port and storage controller port, information is gathered on a connection metric related to a number of paths in which the port is configured and a traffic metric indicating Input/Output (I/O) traffic at the port. A determination is made of available ports for one host and storage controller that are available to provide paths between one host and storage controller. The connection and traffic metrics for the available host ports are processed to select at least one host port. The connection and traffic metrics for the available storage controller ports are processed to select at least one storage controller port. The at least one selected host and storage controller port pair are configured to provide at least one path enabling the host to communicate with the selected storage controller port to access at least one storage volume managed by the selected storage controller. | 12-04-2008 |
20080301333 | SYSTEM AND ARTICLE OF MANUFACTURE FOR USING HOST AND STORAGE CONTROLLER PORT INFORMATION TO CONFIGURE PATHS BETWEEN A HOST AND STORAGE CONTROLLER - Provided are a system and article of manufacture for using host and storage controller port information to configure paths between a host and storage controller. Information is gathered on ports on at least one host, ports on at least one storage controller managing access to storage volumes, and at least one fabric over which the at least one host and storage controller ports connect. For at least one host port and storage controller port, information is gathered on a connection metric related to a number of paths in which the port is configured and a traffic metric indicating Input/Output (I/O) traffic at the port. A determination is made of available ports for one host and storage controller that are available to provide paths between one host and storage controller. The connection and traffic metrics for the available host ports are processed to select at least one host port. The connection and traffic metrics for the available storage controller ports are processed to select at least one storage controller port. The at least one selected host and storage controller port pair are configured to provide at least one path enabling the host to communicate with the selected storage controller port to access at least one storage volume managed by the selected storage controller. | 12-04-2008 |
20090313312 | Method of Enhancing De-Duplication Impact by Preferential Selection of Master Copy to be Retained - A method and apparatus are provided for enhancing the impact of data de-duplication by preferential selection of the master copy to be retained based on current loads and performance metrics of the storage media devices. The computer system is configured to take as input the identified duplicate copies of data and evaluating their locations in storage devices to determine the cumulative affects of retaining one of the identified duplicate copies as a master copy and optionally allocating a new location if needed. Once a master copy has been designated, the remaining identified duplicate copies are removed from storage. | 12-17-2009 |
20100223404 | MANAGEMENT SYSTEM FOR USING HOST AND STORAGE CONTROLLER PORT INFORMATION TO CONFIGURE PATHS BETWEEN A HOST AND STORAGE CONTROLLER IN A NETWORK - Provided is an article of manufacture, system and method for a management system for using host and storage controller port information to configure paths between a host and storage controller in a network. A management system is coupled to a network, wherein the management system communicates over the network with a plurality of hosts, storage controllers, and a network monitor to configure paths in the network between the hosts and the storage controllers in order for the storage controller to provide storage services to the hosts. The network monitor collects statistics from the components in the network. The management system obtains from the network monitor information on ports on at least one host, ports on at least one storage controller managing access to storage volumes, and at least one fabric over which the at least one host and storage controller ports connect. The management system gathers, for at least one host port and storage controller port, information on a connection metric indicating a number of paths in which the port is configured and a traffic metric indicating Input/Output (I/O) traffic at the port. The management system processes the connection and traffic metrics for the host and storage ports to select at least one host port and at least one storage controller port. The management system configures the at least one selected host and storage controller port pair to provide at least one path enabling the host to communicate with the selected storage controller port to access at least one storage volume managed by the selected storage controller. | 09-02-2010 |
