Tintri by DDN Assigned Three Patents

Load balancing VM selection and movement
Tintri by DDN, Inc., Santa Clara, CA, has been assigned a patent (10,956,196) developed by Gritter, Mark G., Eagan, MN, Vempati, Satya, Cupertino, CA, and Popuri, Siva, Mountain View, CA, for “load balancing VM selection and movement.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Load balancing VM selection and movement is disclosed, including: selecting a combined predicted metric to be improved with respect to a plurality of storage devices, and determining a set of VMs to be moved from a first storage device included in the plurality of storage devices to a second storage device included in the plurality of storage devices such that the selected combined metric to improve is predicted to improve.”

The patent application was filed on August 31, 2017 (15/693,251).

Native storage quality of service for virtual machines
Tintri by DDN, Inc., Santa Clara, CA, has been assigned a patent (10,949,103) developed by Sakdeo, Sumedh V., San Jose, CA, Lee, Edward K., Dublin, CA, and Salmon, Brandon W., Menlo Park, CA, for a “native storage quality of service for virtual machines.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Techniques to satisfy quality of service (QoS) requirements on a per virtual machine basis natively in a storage system are disclosed. In various embodiments, for each of a plurality of virtual machines a corresponding input/output (I/O) request queue is stored on the storage system. Requests are scheduled to be pulled from the respective request queues and added to a corresponding storage operation pipeline at the storage system in an order determined based at least in part on a per virtual machine quality of service parameter.”

The patent application was filed on April 24, 2019 (16/393,796).

Handling device in latency state in redundant storage
Tintri by DDN, Inc., Santa Clara, CA, has been assigned a patent (10,936,206) developed by Dittia, Zubin D., San Mateo, CA, for “handling a device in a latency state in a redundant storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”In an embodiment, a system for handling a device in latency state in a redundant storage system includes a processor configured to process a write request to a plurality of devices associated with a redundant storage system. The processor is further configured to receive a set of indications of write successes from a set of devices included in the plurality of devices other than a first device, and send an indication of a completed write to a requestor associated with the write request based at least in part on an indication that the first device meets a set of one or more criteria associated with a latency state. The system further includes a memory coupled to the processor and configured to store the write request.”

The patent application was filed on February 1, 2018 (15/886,156).
