Infinidat Assigned Two Patents

Resynchronization of remote storage site after replication failure
Infinidat Ltd., Herzliya, Israel, has been assigned a patent (9,710,189) developed by Shani, Ayelet, Moshav herev le’et, Israel, for a “resynchronization of a remote storage site after replication failure.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for replicating a local storage entity to provide a remote storage entity, the method may include receiving, by a local storage site, after an occurrence of a replication failure, after-failure remote storage site difference information indicative of differences between, (i) a certain point in time version of the remote storage entity and, (ii) an after-failure point in time version of the remote storage entity, calculating, by the local storage site, after the occurrence of the replication failure, after-failure local storage site difference information indicative of differences between, (i) a certain point in time version of the local storage entity and, (ii) an after-failure point in time version of the local storage entity, and sending, by the local storage site to the remote storage site, local storage entity portions listed in at least one of the after-failure remote storage site difference information and to the after-failure local storage site difference information, during an after-failure replication cycle, and wherein the certain point in time is associated with a last successful replication cycle that preceded the replication failure.“

The patent application was filed on June 18, 2015 (14/742,741).

Automatic failover and failback between primary and secondary storage systems
Infinidat Ltd., Herzliya, Israel, has been assigned a patent (9,703,649) developed by Winokur, Alex, Ramat Gan, Israel, for a “automatic failover and failback between primary and secondary storage systems.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for managing a secondary storage system, the method may include performing a failover update, by the secondary storage system, of a status of at least one secondary path that couples a host computer to the secondary storage system thereby causing the host computer to prioritize sending IO requests to the secondary storage system over sending the IO requests to a primary storage system, wherein the failover update is triggered by a determination made by the secondary storage system that, (a) the secondary storage system is, when making the determination, at an acceptable synchronization level with the primary storage system, and, (b) the primary storage system is disconnected from the host computer, receiving, from the host computer, IO requests, and responding, by the secondary storage system, to the IO requests.“

The patent application was filed on December 18, 2014 (14/574,416).
