Write-back storage cache based on fast persistent memory
Oracle International Corporation, Redwood Shores, CA, has been assigned a patent (10,592,416) developed by Baddepudi, Bharat Chandra, San Jose, CA, Loaiza, Juan R., Woodside, CA, Hu, Wei-Ming, Palo Alto, CA, Umamageswaran, Kothanda, Sunnyvale, CA, Tsukerman, Alex, Foster City, CA, Erlikhman, Boris, Mountain View, CA, Lee, J. William, Belmont, CA, Shi, Jia, Burlingame, CA, Goyal, Kiran B., Mumbai, India, and Aya, Selcuk, Redwood City, CA, for a “write-back storage cache based on fast persistent memory.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A storage device uses non-volatile memory devices for caching. The storage device operates in a mode referred to herein as write-back mode. In write-back mode, a storage device responds to a request to write data by persistently writing the data to a cache in a non-volatile memory device and acknowledges to the requestor that the data is written persistently in the storage device. The acknowledgement is sent without necessarily having written the data that was requested to be written to primary storage. Instead, the data is written to primary storage later.”

The patent application was filed on November 3, 2011 (13/288,785).

Distributed persistent store archival and retrieval in distributed computing
Oracle International Corporation, Redwood Shores, CA, has been assigned a patent (10,585,599) developed by Raja, Harvey, Manchester, Great Britain, Gleyzer, Gene, Lexington, MA, and Middleton, Tim, Perth, Autralia, for “system and method for distributed persistent store archival and retrieval in a distributed computing environment.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A system and method for supporting persistent store archival and retrieval in a distributed computing environment. The system provides a central portal operative to initiate the archiving, (or retrieval) which is executed in parallel across all members with access to persisted stores, either being sent or gathered from an archive repository. The system and method can include an archive coordinator associated with an in-memory data grid. The archive coordinator receives an instruction to store a snapshot of a current state of the in-memory data grid, the instruction including a storage location, the storage location being a destination selected from the group consisting of a local disk and a shared disk. The system can archive the snapshot of the current state of the in-memory data grid at the storage location.”

Optical storage system divider based draw verification with high frequency writing strategy pattern
Oracle International Corporation, Redwood Shores, CA, has been assigned a patent (10,580,449) developed by Wang, Lingtao, Broomfield, CO, for an “optical storage system divider based draw verification with high frequency writing strategy pattern.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”An optical storage system includes an optical head configured to split a light beam into a higher power main beam and at least one lower power side beam. The optical storage system also includes a controller configured to alter an optical medium, via modulation of the higher power main beam according to a writing strategy waveform that defines at least n pulses for every n bits of data to be written to the medium, while processing a first signal resulting from the at least one lower power side beam being reflected from the medium and a second signal indicative of the writing strategy waveform to remove noise from the first signal caused by the higher power main beam to generate output indicative of the data directly after writing.”

The patent application was filed on January 7, 2019 (16/241,534).

Cloud migration of file system data hierarchies
Oracle International Corporation, Redwood Shores, CA, has been assigned a patent (10,558,699) developed by Maybee, Mark, Boulder, CO, Kremer, James, Longmont, CO, and Ledru, Pascal, Broomfield, CO, for a “cloud migration of file system data hierarchies.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Techniques described herein relate to systems and methods of data storage, and more particularly to providing layering of file system functionality on an object interface. In certain embodiments, file system functionality may be layered on cloud object interfaces to provide cloud-based storage while allowing for functionality expected from a legacy applications. For instance, POSIX interfaces and semantics may be layered on cloud-based storage, while providing access to data in a manner consistent with file-based access with data organization in name hierarchies. Various embodiments also may provide for memory mapping of data so that memory map changes are reflected in persistent storage while ensuring consistency between memory map changes and writes. For example, by transforming a ZFS file system disk-based storage into ZFS cloud-based storage, the ZFS file system gains the elastic nature of cloud storage.”

Predicate offload of large objects
Oracle International Corporation, Redwood Shores, CA, has been assigned a patent (10,489,365) developed by Marwah, Vineet, San Ramon, CA, Ganesh, Amit, San Jose, CA, Lee, Teck Hua, Belmont, CA, Chang, Hui Joe, San Jose, CA, and Liu, Zhen Hua, San Mateo, CA, for a “predicate offload of large objects.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”In an approach, the database server generates a request for data representing rows of a table, the request identifying one or more data blocks stored on a storage system. The database server then generates metadata describing one or more filtering conditions to be applied to the rows and sends the metadata along with the request to the storage system. The storage system, when applying filtering conditions to a column containing a LOB, determines whether the LOB is stored in-line or out-of-line. If the column contains an out-of-line LOB, the storage system skips the filtering conditions on the column. If the column contains an in-line LOB, the storage system applies the filtering conditions to the column. Upon obtaining the filtered data from the storage system, the database server retrieves the data blocks for out-of-line LOBs and applies the skipped filtering conditions to create a final result set.”

The patent application was filed on March 14, 2013 (13/831,137).

The first drive tray may be coupled to the network switch and include a first hardware processor that sends status information about a first hardware device to the base module apparatus over a first network path. The second drive tray may also be coupled to the network switch and include a second hardware processor that sends status information about a second hardware device to the base module apparatus over a second network path. Network addresses may be assigned to the hardware devices based on the module’s position in the library relative to the base module.”
