Infinidat Assigned Three Patents

Comparison of file system snapshots stored in remote storage
Infinidat Ltd., Herzlia, Israel, has been assigned a patent (10,437,787) developed by Plisko, Cyril, Petah Tikvah, Israel, Goldberg, Alexander, Rehovot, Israel, and Kull, Leon, Yehud, Israel, for a “comparison of file system snapshots stored in a remote storage system using a network file system command.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method for performing a comparison between first and second points in time snapshots of a file system entity, the method may include: (I) receiving by a storage system a command that was sent from a host computer, the command is network file system protocol compliant, wherein the command comprises (i) an operation code, and (ii) information about a virtual path, the virtual path that comprises, ii.a) first fields that comprise snapshot comparison parameters indicative of the first and second points in time snapshots of the file system entity, and (ii.b) a second field of a content that indicates that the command is a request to compare between the first and second points in time snapshots of the file system entity (II) identifying, by a file system application hosted by the storage system and in response to the content of the second field of the virtual path, the command as including a request to compare between the first and second points in time snapshots of the file system entity (III) comparing by the file system application the first and second points in time snapshots of the file system entity to provide a comparison result that is network file system protocol compliant, and (IV) sending by the storage system the comparison result to the host computer.”

The patent application was filed on November 24, 2013 (14/088,401).

Replicating storage entity stored in given storage system to multiple other storage systems
Infinidat Ltd., Herzlia, Israel, has been assigned a patent (10,437,508) developed by Medan, Yoav, Haifa, Israel, for a “replicating a storage entity stored in a given storage system to multiple other storage systems.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A storage system, a computer program product and method for replicating a storage entity to a group of storage systems. The method may include splitting the storage entity, by a given storage system, to provide storage entity portions, generating, by the given storage system, storage entity portions information for distributing the storage entity portions between all storage systems of the group so that each storage system of the group eventually receives the storage entity portions, transmitting the storage entity portions, from the given storage system, to storage systems of the group, wherein the transmitting comprises transmitting different storage entity portions from the given storage system to different storage systems of the group, sending, by the given storage system, the storage entity portions information to at least some storage systems of the group, and attempting to verify, by the given storage system, that all the storage systems of the group received all the storage entity portions.”

The patent application was filed on August 9, 2017 (15/672,331).

Shared layered physical space.
Infinidat Ltd., Herzliya, Israel, has been assigned a patent (10,430,087) developed by Yochai, Yechiel, Moshav Aviel, Israel, Dorfman, Mike, Herzliya, Israel, and Tal, Sivan, Yifat, Israel, for a “shared layered physical space.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method for managing write requests in a storage system, the method may include receiving, by a receiving control node out of a group of control nodes of the storage system, a write request for writing a data unit to the storage system; storing the data unit in a first layer storage that is shared among the control nodes of the group, by the receiving control node; retrieving the data unit from the first layer storage and destaging the data unit to a second layer storage by a destaging control node that belongs to the group and is responsible for destaging the data unit; wherein at a time of the destaging of the data unit to the second layer storage another control node of the group is responsible for destaging another data unit to the second layer storage; wherein the storing of the data unit in the first layer storage is faster than the destaging of the data unit to the second layer storage; and when the destaging control node differs from the receiving control node then each one of the receiving and the storing is not preceded by notifying the destaging control node about the receiving and the storing, respectively.”

The patent application was filed on February 1, 2017 (15/421,449).
