The present invention discloses a solution for migrating an application session from one device to another. In the solution, a migration event can be detected during an application session involving an application server and an original device. Client-side session information and server-side session information can be stored. The client-side session information can be conveyed to a transfer device, which establishes a communication connection with the application server. This session can occur after an arbitrary delay from an occurrence of the migration event. Transfer device settings can be changed in accordance with the client-side session information and application server settings can be changed in accordance with the stored server-side information. An application session involving the transfer device and the application server can be conducted, beginning in a state approximately equivalent to that which existed at the time of the migration event.

The present disclosure relates to systems and methods for RAID Restriping. One method includes selecting an initial RAID device for migration based on at least one score, creating an alternate RAID device, moving data from the initial RAID device to the alternate RAID device, and removing the initial RAID device. The method may be performed automatically by the system or manually. The method may be performed periodically, continuously, after every RAID device migration, upon addition of disk drives, and/or before removal of disk drives, etc. One system includes a RAID subsystem and a disk manager configured to automatically calculate a score for each RAID device, select a RAID device based on the relative scores of the RAID devices, create an alternate RAID device, move data from the selected RAID device to the alternate RAID device, and remove the selected RAID device.

Releasing a data set at a source device in connection with migrating data from the source device to a target device includes mapping application address space to address space containing metadata for the target device and providing additional local metadata therefor, replacing within the application the address of metadata for the source device with the address of metadata for the target device, setting a diversion flag that is part of the additional local metadata, where the diversion flag indicates a remapping of extent, and closing and unallocating the data set at the source device. Releasing a data set at a source device in connection with migrating data from the source device to a target device may also include determining if an application uses standard I/O operations. The metadata may include UCB data.

A network server migrates dataset blocks from a source storage device to a target storage device while continuing to service user requests for the data stored in the dataset blocks. A control driver executing at the network server tracks the location of the dataset blocks during the data migration as being at either the source storage device or the target storage device. Upon receiving a user request for the data, the control driver uses the tracking information to determine whether the dataset blocks associated with the requested data have been migrated to the target storage device or are still stored at the source storage device. The control driver then retrieves the data associated with the requested dataset blocks from the determined source or target storage device.

A low profile occlusion device for percutaneous or direct transcutaneous placement into a vein or other tubular vessel of the body. Two wires form one or more loops having a thin cover disposed between them. The loop forms a beveled angle within the blood vessel and the cover prevents blood flow through the vessel. An additional loop can be present to prevent device embolization or device migration. The occlusion device is delivered to a vein such as an incompetent perforator vein or other incompetent vein through a small flexible sheath. Ultrasound guidance is used to position the occlusion device which can be repositioned within the vessel if necessary.

Techniques for maintaining connectivity between a remote application stored on a remote device and an application being executed in a system environment, wherein the system environment is migrated from a first device to a second device, are provided. A first connection between the remote application stored on the remote device and the application being executed in the system environment stored on the first device is established via a first communication over a first negotiation channel.

The first connection between the remote application and the application being executed in the system environment is disconnected for migration of the system environment from the first device to the second device. Disconnecting the first connection is coordinated via the first negotiation channel. A second connection between the remote application stored on the remote device and an application being executed in the migrated system environment stored on the second device is established via a second communication over a second negotiation channel. The second negotiation channel connects a third socket layer interface linked to the application being executed in the migrated system environment to the second socket layer interface linked to the remote application.

An appliance migration mechanism (AMM) optimizes migration of a live virtual appliance with virtual objects between cloud environments to minimize temporary connections that use significant cloud resources during the migration. The AMM determines a cost of connections of each virtual object in the virtual appliance and produces an order of migration for the virtual objects. The cost of connections of the virtual objects may be determined by the total number of connections and the maximum number of connections. Alternatively the cost of the connections of the virtual objects for migration could be determined by a weighting the costs of the connections where the weighting may consider loading or other factors on the connection.
