Elastifile Assigned Patent

Elastifile Ltd., Herzlia, Israel, has been assigned a patent (9,465,558) developed by Hoch, Ezra N., Tel-Aviv, Israel, and Weissbrem, Eliyahu, Rehovot, Israel, for a “distributed file system with speculative writing.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for data storage includes running on multiple interconnected compute nodes respective virtual heads that collaboratively store files in persistent storage. In response to receiving in an initiator virtual head a request to write at least a portion of a given file, the initiator virtual head selects one or more destination virtual heads for storing the portion. The portion is sent from the initiator virtual head to the selected destination virtual heads, and a notification of the selected destination virtual heads is sent to an owner virtual head, which has been assigned to own metadata of the portion. In the destination virtual heads, the portion received from the initiator virtual head is cached, and committed to the persistent storage only in response to receiving a commit instruction from the owner virtual head.“

The patent application was filed on January 13, 2015 (14/595,234).
