Infinidat Assigned Two Patents

Storage system capable of managing plurality of snapshot families
Infinidat Ltd., Herzliya, Israel, has been assigned a patent (9,383,942) developed by Ezra, Josef, Even Yehuda, Israel, Yochai, Yechiel, Moshav Aviel, Israel, Ben-Tsion, Ido, Ramat Gan, Israel, and Zeidner, Efraim, Haifa, Israel, for a “storage system capable of managing a plurality of snapshot families and method of operating thereof.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”There is provided a storage system comprising a control layer operable to manage a snapshot family, (SF) constituted by SF members having hierarchical relations represented by a SF relationship data structure and a method of operating thereof. Upon receiving a command for restoring a writable SF member from a read-only snapshot thereof, the control layer provides a foreground atomic operation. The atomic operation comprises generating a new writable snapshot of the read-only snapshot, a destination SF member, modifying the SF relationship data structure, and re-assigning all logical unit numbers, (LUNs) from the writable SF member to be restored to the destination SF member. Upon successful completion of the atomic operation, the control layer sends acknowledgement indicative of successful restoring the writable SF member. The control layer further provides a background process comprising modifying, in correspondence with the provided atomic operation, a SF mapping data structure comprising mappings between logical and physical addresses corresponding to SF members.“

The patent application was filed on November 27, 2013 (14/092,208).

Managing volume updates received during execution of volume migration process
Infinidat Ltd., Herzliya, Israel, has been assigned a patent (9,372,631) developed by Rozendorn, Guy, and Yalon, Tal, Tel Aviv, Israel, for a “managing volume updates received during an execution of a volume migration process.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method for updating a destination volume, the method may include monitoring duplicate traffic that represents original traffic that is exchanged between at least one host computer and a first storage system, wherein the monitoring is executed by a controller during an execution of a migration or a replication of a source volume of the first storage system to a destination volume of a second storage system, wherein the controller is not included in the first storage system, wherein the original traffic is related to the source volume, wherein the duplicate traffic is sent toward the controller by at least one switch that attempts to duplicate the original traffic, and controlling, based upon the monitoring, a process of updating the destination volume with a set of source volume updates, wherein the set of source volume updates are reflected in the duplicate traffic and are received during the execution of the migration.“

The patent application was filed on December 24, 2014 (14/582,254).
