End-to-end encryption with data deduplication
Red Hat, Inc., Raleigh, NC, has been assigned a patent (11620399) developed by BenHanokh, Gabriel Zvi, Tel-Aviv, Israel, and Wasserman, Orit, Mitzpe Aviv, Israel, for an “end-to-end encryption with data deduplication.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Aspects and features of the present disclosure can provide encryption to maintain data privacy while allowing deduplication of some client data by or cloud-based storage platforms. Data can be identified as public data and left unencrypted so that it can be deduplicated. Other data can be identified as personal data, which can be encrypted with a personal key, or as group data, which can be encrypted with a shared, group key. Identifying the data can include storing the data in storage regions within a closed environment. The storage regions can be established, at the client, in a storage platform, or both. Optionally, a storage platform can include multiple storage regions for multiple groups of users, wherein each group is assigned its own unique encryption key. Such data can thus automatically be subject to the same deduplication routines as unencrypted data.”

Managing client devices associated with storage nodes in scale-out storage
Red Hat, Inc., Raleigh, NC, has been assigned a patent (11593035) developed by BenHanokh, Gabriel Zvi, Tel-Aviv, Israel, and Durgin, Joshua, Canyon Country, CA, for “managing client devices associated with storage nodes in a scale-out storage system.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Client devices associated with scale-out storage nodes can be managed based on scale-out storage nodes having backup power supplies. For example, a management node of a scale-out storage system can determine, from among a plurality of storage nodes of the scale-out system, that a first storage node is uncoupled to a backup power supply and that a second storage node is coupled to the backup power supply. The management node can receive device characteristics describing a type of workload and a configuration for a client device associated with the first storage node. The management node can determine the client device satisfies a migration policy based on the device characteristics. The management node can migrate the client device to the second storage node based on the client device satisfying the migration policy.”

High performance space efficient distributed storage
Red Hat, Inc., Raleigh, NC, has been assigned a patent (11550755) developed by Das, Gobinda, Bengaluru, India, for a “high performance space efficient distributed storage.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “High performance space efficient distributed storage is disclosed. For example, a distributed storage volume (DSV) is deployed on a plurality of hosts, with a first host storing a local cache, and a storage controller executing on a processor of the first host receives a request to store a first file. The first file is stored to the local cache. The DSV is queried to determine whether a second file that is a copy of the first file is stored in the DSV. In response to determining that the DSV lacks the second file, the first file is transferred from the local cache to the DSV and then replicated to a second host of the plurality of hosts. In response to determining that the second file resides in the DSV, a reference to the second file is stored in the DSV and then replicated to the second host.”
