Oracle Assigned Three Patents

Dynamic creation of replicas of streaming data
from storage device without added load
Oracle America, Inc., Redwood City, CA, has been assigned a patent (8,458,125) developed by Fay Chong Jr., Cupertino, CA, and Whay S. Lee, Milpitas, CA, for a "dynamic creation of replicas of streaming data from a storage device without added load."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A method, and corresponding system, is provided for generating replicas or copies of data objects that are used to serve data streams. The method includes determining one of the storage devices is operating at a load above a predetermined overload value. The method continues with identifying the data objects being served by data streams from the near overload storage device and then, selecting one of these served data objects for replication. To create a replica, the method includes writing data from the selected data object to another less busy one of the storage devices, with the writing being done using data from one or more of the streams being served from the selected data object on the near-overload storage device. During replica creation, one or more streams from the selected data object provide data concurrently to a stream consumer or client device and to the replica."

The patent application was filed on Jan. 31, 2005 (11/046,917).

Direct read after write for optical storage device
Oracle International, Redwood City, CA, has been assigned a patent (8,451,702) developed by Faramarz Mahnad, Brookline, MA, for a "direct read after write for optical storage device."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "Systems and methods for storage on an optical medium having a plurality of tracks include splitting a light beam into a higher power main beam and at least one lower power side beam that form corresponding spots spaced along a selected one of the plurality of tracks and selectively positioning and aligning the beams/spots along the selected one of the plurality of tracks using the higher power main beam to write data while reading previously written data using the at least one lower power side beam. The systems and methods may include correlating the read signal with a time-shifted write signal to provide a direct read after write capability to verify data written to the optical medium. In one embodiment, an optical tape drive includes an optical pickup unit that generates a lower power satellite beam to read data directly after writing by a higher power main beam."

The patent application was filed on Aug. 22, 2011 (13/214,662).

Storage system and method
of processing data access request
Oracle America, Inc. filed patent application (WO2010117745) for "storage system and method of processing a data access request.".

The US inventors are John Timothy Obrien, Michael Steven Milillo, George Franklin Detar, and Carl Thomas Madison.

According to the Controller General of Patents, Designs & Trade Marks, "A storage system includes a plurality of servers a plurality of external interface providers each deployed on one of the servers and a plurality of storage controllers each deployed on one of the servers. Each of the providers is configured to receive a data access request to identify one of the controllers that can satisfy the request and to forward the request to the identified controller. The system further includes a plurality of storage modules independent of the servers. The providers controllers and modules are in communication with each other. Each of the controllers exclusively manages a portion of data content in at least one of the modules and satisfies data access requests received from the providers by accessing the portion of data content in the at least one module."

The patent application was filed on Sept. 26, 2011 (6936/CHENP/2011 A)
