    Abstract: A computer system has a storage system including a first port and a second port, and a relay apparatus which couples the first port to an initiator apparatus. The storage apparatus stores relay apparatus information indicating a relay apparatus, and initiator information indicating an initiator apparatus. The storage apparatus establishes communications between the first port and a first relay apparatus, and based on communications with the relay apparatus recognizes the initiator apparatus with which the first relay apparatus has established communications. The storage apparatus also stores, in pathway information, a first pathway containing the first port, the first relay apparatus and the initiator apparatus. The storage apparatus creates a virtual port, which is a virtual port to which the first port is allocated, and when an initiator apparatus establishes communications with the virtual port, this apparatus adds a first virtual port associated pathway, in which the virtual port is associated with the first pathway, to the pathway information.

    Abstract: Methods, storage arrays and computer readable media for triggering a failover between an active controller and a standby controller of a storage array are provided. One method includes determining by the active controller a number of connected fabrics available between ports of the active controller and a host and determining by the standby controller a number of connected fabrics available between the ports of the standby controller and the host. The method further includes executing a policy configuration to determine if the number of connected fabrics for each of the active controller and the standby controller meet a threshold for triggering the failover. The failover being a forced failover where the active controller takes a role of the standby controller and the standby controller takes a role of the active controller.

    Abstract: Scalable data storage techniques are described. In one or more implementations, data is obtained by one or more computing devices that describes fault domains in a storage hierarchy and available storage resources in a data storage pool. Operational characteristics are ascertained, by the one or more computing devices, of devices associated with the available storage resources within one or more levels of the storage hierarchy. Distribution of metadata is assigned by the one or more computing devices to one or more particular data storage devices within the data storage pool based on the described fault domains and the ascertained operational characteristics of devices within one or more levels of the storage hierarchy.

    Abstract: A method performed by a storage system includes a first storage processor performing input/output (IO) requests on a first one or more logical units, and a second storage processor performing IO requests on a second one or more logical units. If the first storage processor fails, the third storage processor performs the IO requests on the first one or more logical units. If the second storage processor fails, the fourth storage processor performing the IO requests on the second one or more logical units.
