EMC IP Holding/Dell Assigned Four Patents

Migrating virtual tapes between different virtual tape storages without host involvement
EMC IP Holding Company, LLC (Dell Technologies, Inc.), Hopkinton, MA , has been assigned a patent (11,340,818) developed by Ashkadov, Dmitry, Murino, Russia, Kotov, Yuri, and Alekseev, Vladislav, Saint Petersburg, Russia, for “migrating virtual tapes between different virtual tape storages without host involvement.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Migrating virtual tapes between different virtual tape storages without host involvement is described herein. A system as described herein can include a local tape library comprising respective storage devices, a memory that stores executable components, and a processor that executes the executable components stored in the memory. The executable components can comprise a connection component that establishes a first connection to a host system and a second connection to an external tape library, a request processing component that receives an access request for a requested storage device from the host system via the first connection, and a proxy component that accesses the requested storage device at the outside tape library via the second connection and enables access to the requested storage device by the host system via the first connection in response to the requested storage device being determined to be absent from the local tape library.”

The patent application was filed on July 26, 2019 (16/523,318).

Disaster recovery specific configurations, management, and application
EMC IP Holding Company, LLC (Dell Technologies, Inc.), Hopkinton, MA , has been assigned a patent (11,281,550) developed by Tolstoy, Mikhail, Kupriyanov, Roman, Saint Petersburg, Russia, Kelley, Karyn, Peabody, MA, McCloskey, Larry, Billerica, MA, and Matveevskiy, Igor, Saint Petersburg, Russia, for “disaster recovery specific configurations, management, and application.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A mechanism for disaster recovery configurations and management in virtual tape applications. Specifically, the introduction of an additional computer process executing at an active datacenter site and at another active (or alternatively, a standby) datacenter site permit: (i) the generation and management of global configurations implemented on the active datacenter site prior to the occurrence of a failover event; and (ii) the implementation of global configurations on the another active (or standby) datacenter site after the occurrence of the failover event.”

The patent application was filed on November 19, 2019 (16/688,812).

Concurrent tape modification
EMC IP Holding Company, LLC (Dell Technologies, Inc.),Hopkinton, MA , has been assigned a patent (11,262,952) developed by LeCrone, Douglas E., Hopkinton, MA, McCloskey, Larry, Hamilton, MT, Goodwill, Richard, Shrewsbury, MA, and Feeney, Martin, Medway, MA, for a “concurrent tape modification.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Writing new data to a tape volume of a tape emulation unit includes determining if the new data is an update to data that was previously written, writing the new data to a new section of the tape emulation unit in response to the new data not updating data that was previously written, deleting the data that was previously written and writing the new data to a new section in response to the new data updating data that was previously written, the new data being larger than the data that was previously written, and the underlying file system not supporting variable size records/blocks, and overwriting the data that was previously written in response to the new data updating data that was previously written and either the new data not being larger than the data that was previously written or the underlying file system supporting variable size records/blocks.”

The patent application was filed on July 19, 2019 (16/516,558).

Indirect storage data transfer
EMC IP Holding Company, LLC (Dell Technologies, Inc.), Hopkinton, MA , has been assigned a patent (11,226,756) developed by LeCrone, Douglas E., Hopkinton, MA, for an “indirect storage data transfer.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Transferring data between a first storage device coupled to a host computing system and a second storage device coupled to the first storage device includes the first storage device receiving a command from the host computing system, the first storage device determining if the command is an out-of-band (OOB) storage command, and, if the command is an OOB storage command, the first storage device sending a command to the second storage device to cause data to be transferred directly between the first storage device and the second storage device independent of the host computing system. Transferring data between a first storage device coupled to a host computing system and a second storage device coupled to the first storage device may also include the first storage device emulating a host computing system in connection with communicating with the second storage device. The second storage device may be a tape emulation unit.”

The patent application was filed on July 26, 2018 (16/045,860).
