Storage system and method for reducing energy consumption
Infinidat Ltd., Herzliya, Israel, has been assigned a patent (9,152,332) developed by Kopylovitz, Haim, Herzliya, Isarel, and Corry, Leo, Ramat Gan, Israel, for a “storage system and method for reducing energy consumption.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A system and method that include configuring local disk drives of a local storage system so that at any given point of time, a first part of the local disk drives operate in a low power state and a second part of the local disk drives operate in an active state, and in response to a read request of a data portion on a local disk drive of the local disk drives: determining whether the local disk drive currently operates in the low power state, reading the data portion from the local disk drive, if the local disk drive does not currently operate in the low power state, if the local disk drive currently operates in the low power state, enquiring if a remote mirror disk drive that stores a copy of the data portion currently operates in the low power state, wherein the remote mirror disk drive is comprised in a remote storage system that is coupled to the local storage system, and if the remote mirror disk drive does not currently operate in the low power state, requesting from the remote storage system to read the copy of the data portion from the remote minor disk drive.“

The patent application was filed on December 10, 2014 (14/565,469).

Access control to stored information and system thereof
Infinidat Ltd., Herzliya, Israel, has been assigned a patent (9,147,081) developed by Satran, Julian, Haifa, Israel, for a “method of access control to stored information and system thereof.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”The presently disclosed subject relates at least to a method and system for controlling access to a logical unit, (LU) in a logical storage space, available to a given initiator, representing a corresponding physical storage space, said logical storage space being accessible via a storage control layer, said storage control layer being associated with a security manager. A first value is generated by the security manager, based on a secret key, and transmitted to host requesting permission to access the logical storage space, while the secret key is made available to a target associated with the logical storage space. The host sends to the control device an access related request, the request comprising a second value which was generated based on the first value. Responsive to the command the target calculates the first value, based on the secret key and the second value based on the first value. The second value is validated with the help of said secret key and the respective access is allowed in case the second value is validated.“

The patent application was filed on July 26, 2011 (13/190,919).

Storage system capable of managing plurality of snapshot families
and method of snapshot family based read
Infinidat Ltd., Herzliya, Israel, has been assigned a patent (9,146,877) developed by Ezra, Josef, Even Yehuda, Israel, Yochai, Yechiel, Moshav Aviel, Israel, Ben Tsion, Ido, Ness-Ziona, Israel, and Zeidner, Efraim, Haifa, IIsrael, for a “storage system capable of managing a plurality of snapshot families and method of snapshot family based read.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method for a snapshot family based reading of data units from a storage system, the method comprises: receiving a read request for reading a requested data entity, searching in a cache memory of the storage system for a matching cached data entity, if not finding the matching cached data entity then: searching for one or more relevant data entity candidates stored in the storage system, selecting, out of the one or more relevant data entity candidates, a selected relevant data entity that has a content that has a highest probability, out of contents of the one or more relevant data entity candidates, to be equal to the content of the requested data entity, and responding to the read request by sending the selected relevant data entity.“

The patent application was filed on March 6, 2014 (14/198,632).

Managing read operations, write operations and extent change operations
Infinidat Ltd., Herzliya, Israel, has been assigned a patent (9,104,325) developed by Yochai, Yechiel, Moshav Aviel, Israel, Ezra, Joseph, Even Yehuda, Israel, Ben-Tsion, Ido, Ness-Ziona, Israel, and Zeidner, Efraim, Haifa, Israel , for a “managing read operations, write operations and extent change operations.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method for responding to an extent change operation, the method may include receiving, by a storage system and from a requesting entity, a request to perform an extent content change operation that involves changing a content of a certain extent within a logical space supported by a storage system, generating, in response to the request, extent change operation information that comprises, a) an event counter indicative of a time of requested occurrence of the extent change operation,, ii) a type of extent change operation indicator, and, ii) logical addresses associated with the extent change operation, and sending to the requesting entity an acknowledgement indicative of a completion of the extent change operation before a completion of the extent change operation if an expected content of the certain extent is known before completion of the extent change operation.“

The patent application was filed on November 13, 2013 (14/078,558).
