摘要： Migrating data from an old storage device to a new storage device includes creating new paths to the new storage device, freezing old paths to the old storage device, transferring metadata corresponding to the old storage device to the new storage device, where state information is transferred from the old storage device to the new storage device, and thawing the new paths. Migrating data from an old storage device to a new storage device may also include creating new volumes on the new storage device and transferring data from the old storage device to the new storage device. Migrating data from an old storage device to a new storage device may also include dismantling the old paths.

摘要： Migrating data from an old storage device to a new storage device includes transferring the data from a first logical device on the old storage device to a second logical device on the new storage device, determining replication relationships for the first logical device, transferring the replication relationships; and transferring logical devices used for the replication relationships from the old storage device to the new storage device. The replication relationships may include a clone of the first logical device. Migrating data from an old storage device to a new storage device may also include suspending writes to the first logical storage device prior to transferring the data for the first logical storage device. The replication relationships may include at least one snapshot.

摘要： Migrating an active VM from a first data center to a second data center having a passive counterpart of the active VM includes freezing the active VM at the first data center, creating an active VM at the second data center that corresponds to the passive counterpart, and restarting the active VM at the second data center. Migrating an active VM from a first data center to a second data center may also include waiting for the passive counterpart to be synchronized with the active VM at the first data center prior to converting the passive counterpart. Creating the active VM at the second data center may include providing a snapshot of a volume containing the passive VM.

摘要： Described are techniques for performing dynamic binding of device identifiers to data storage devices. A first device identifier assigned to an application on a host is received. The first device identifier is a unique detachable device identifier dynamically bound to different data storage devices at different points in time in accordance with data storage devices used by the application. The first device identifier is attached to a first data storage device of the data storage system used by the application at a first point in time. The first device identifier is detached from the first data storage device thereby making the first data storage device unavailable for data operations from the application. The first device identifier is attached to a second data storage device used by the application at a second point in time thereby making the second data storage device available for data operations from the application.

摘要： Sharing at least one link among a plurality of processes includes determining a capacity of the at least one link based on a number of I/O operations per unit time supported by the at least one link as a function of the amount of data provided by each of the I/O operations, determining a requirement of each of the processes based on user specifications and an amount of data provided by each I/O operation for each of the processes, and apportioning link capacity among the processes according to the requirement of each of the processes. In response to a sum of requirements for each of the processes being less than the capacity of the at least one link, additional link capacity may be provided to at least some of the processes.

摘要： A mechanism to support remote mirroring of storage devices by data storage systems in a one-to-many switched environment. Each data storage system includes a disk director that is adapted to control at least one device group that is supported in a mirrored configuration with a corresponding device group controlled by one of the other data storage systems. For each device group and corresponding device group, there are first ports associated with the device group and second ports associated with the corresponding device group. A switch element is adapted to connect one of the first ports to at least one of the second ports so that data may be exchanged between the ports for each device group and corresponding device group. The disk director selects which first port is to be connected to which second port via the switch element in the establishment of a logical link. Thus, each port connected to the switch is capable of achieving multiple connections to multiple destinations for increased connectivity, redundancy and performance (load balance) without additional hardware.

摘要： Providing data from a volume of a remote storage device coupled to a local storage device that is coupled to a host, includes providing a command to the remote storage device to request the data, if the data is stored in a cache portion of the remote storage device, the remote storage device providing the data, and if the data is not stored in the cache portion of the remote storage device, the remote storage device causing the data to be fetched from the volume and returning one of: a disconnect or an indicator that the data was not found. Causing the data to be fetched from the volume may include creating a separate wait task that waits for the data to be fetched from the volume. The separate wait task may be created only if there is not already another wait task waiting for the same data. The wait task may post an error if the data is not fetched after a predetermined amount of time, such as four seconds. An error may be posted if the data is not fetched after a predetermined amount of time, such as eight seconds. After the data has been fetched from the volume, the remote storage device may provide a reconnect command followed by the data.

摘要： A method for scanning a message-list accessible to a plurality of processors includes retrieving, from a cache associated with a scanning processor from the plurality of processors, information identifying a starting message-slot. This information is then used to begin a scan of the message-list at that starting message-slot. The information indicating the starting message-slot is obtained by identifying, in the message-list, a message-slot containing a message intended for a recipient processor from the plurality of processors and obtaining, from the identified message-slot, information indicative of a location of a succeeding message-slot in the message-list. This information is then cached, for retrieval during a subsequent scan of the message-list.
