    摘要： A method for routing communication paths among computing devices. The method includes a one or more computer processors identifying a computing entity and a data storage entity that transfer data. The method further includes determining a plurality of communication ports that the data storage entity utilizes to transfer data to the computing entity. The method further includes identifying a plurality of computing resources respectively associated with the determined plurality of communication ports that the data storage entity utilizes to transfer the data to the computing entity. The method further includes generating a list of tuples for the data storage entity based, at least in part, on the identified plurality of computing resources and the determined plurality of communication ports.

    摘要： Aspects of the present disclosure relate to transmitting prioritized path data to a device based on a set of topology rules and metrics associated with a storage target. A storage target path discovery request is received from the device. In response to the storage target path discovery request, metrics associated with the storage target are collected. Based on the collected metrics, available paths to the storage target are identified. A set of topology rules are then determined. Based on the topology rules and the collected metrics, a subset of available paths are selected. The subset of available paths are then prioritized into prioritized path data. The prioritized path data is then stored and transmitted to the device.

    摘要： When a volume that was once associated with a consistency group and is to be deleted from the storage system, the to be deleted volume is designated as a ghost volume within the storage system, and the deletion of the ghost volume from the storage system is delayed until there are no snapshots that include a pointer to the ghost volume. The storage system may include a counter that counts the number of instances all volumes within a consistency group are pointed to or that counts the number of instances that only ghost volumes are pointed to. The storage system may reference this count to determine whether to immediately delete or delay the deletion of the volume from the storage system.

    摘要： Connectivity type detection for a data storage system in accordance with the present description includes, in one aspect of the present description, automated host-target discovery logic which is configured to automatically discover the connectivity type for a connection path between a host and a storage system, and select and initiate target discovery procedures which are appropriate for the discovered connectivity type. As a result, mapping a target volume of the target storage system which is connected to the host, may be facilitated, reducing or eliminating delays which may have otherwise resulted from the change in connectivity type. In this manner, efficiency of the computing system may be improved. Other aspects and advantages may be realized, depending upon the particular application.

    摘要： Methods, computing systems and computer program products implement embodiments of the present invention that include receiving a request including a specified number of logical volumes, and identifying, in a storage system including multiple storage pools having storage space, respective first amounts of the storage space that are available in the multiple storage pools. Based on the specified number of logical volumes and the first amounts of the storage space, a set of volume sizes indicating second amounts of the storage space are defined, and a given volume size indicating a maximum size for the specified number of logical volumes is identified. Upon conveying the maximum size to a user, and receiving, from the user, a specified size less than or equal to the maximum size, the specified number of the volumes having the specified size can be provisioned, wherein each of the volumes is stored in a given storage pool.
