摘要： A system comprises a first storage system, a second storage system, a plurality of switches, and a server connected with the first storage system via a first group of switches and connected with the second storage system via a second group of switches. The first group and the second group have at least one switch which is not included in both the first and second groups. The first storage system receives I/O commands targeted to first logical units from the server via the first group of switches. The first storage system maintains first information regarding the ports of both the first and second storage systems. The first information is used to generate multipath communication between the server and the first storage system, including at least one path which passes through the second storage system and at least one other path which does not pass through the second storage system.

摘要： In one implementation, a system includes multiple SCSI nodes configured to perform a SCSI target function. Each of the multiple SCSI nodes includes a host bus adaptor configured to connect the SCSI node with a Fibre Channel fabric. The host bus adaptor being assigned a world wide name and a network address. The system further includes a host configured to perform a SCSI initiator function. The world wide name assigned to a source host bus adaptor associated with one SCSI node is relocated to a target host bus adaptor associated with another SCSI node. After that, the network address associated with the source host bus adaptor is relocated to the target host bus adaptor. In one implementation, the system determines whether or not a network address assigned to a source host bus adaptor associated with one of the multiple SCSI nodes is shared with at least one other service. If so, the system determined whether the shared network address can be relocated to a target host bus adaptor associated with another one of the multiple of SCSI nodes. If the latter determination is in affirmative, the world wide name and network address are relocated.

摘要： A system for input/output path switching comprises a host; a network switch coupled to the host; and a plurality of storage systems which include a first storage system and a second storage system. For switching an I/O path, from a path between the host and the first storage system via the network switch to another path between the host and the second storage system via the network switch, one of the host or the network switch changes FCID (Fibre Channel Node port identifier) information therein, to migrate a WWPN (World Wide Port Name) from association with the first storage system network interface to association with the second storage system network interface. The FCID information includes address information of storage system network interfaces of the storage systems for connecting to the network switch.

摘要： For storage management in a tiered storage environment in a system having one or more applications running on a host computer which is connected to a storage system, the storage system comprises storage volumes in a pool which are divided into a plurality of tiers having different tier levels, the tiers being organized according to a tier configuration rule; and a controller. The controller allocates the pool to a plurality of virtual volumes based on a change of the tier levels against the physical storage devices. The controller stores a relation between data in the storage system being accessed by each application running on the host computer and an application ID of the application accessing the data. The tier level of a portion of a storage volume of the plurality of storage volumes is changed based at least in part on the application accessing data in the storage volume.
