  • Preserving Data Deduplication in a Multi-Tenant Storage System
    Publication number: 20230004315
    Abstract: A method includes receiving a request to write a data block to a volume resident on a multi-tenant storage array, wherein the request is associated with a first tenant of the multi-tenant storage array, and determining whether the data block matches an existing data block on the multi-tenant storage array, wherein the existing block corresponds to a second tenant. In response to determining that the decrypted data block matches the existing data block: encrypting the existing data block with a shared volume encryption key; encrypting the shared volume encryption key with a first tenant encryption key and providing the shared volume encryption key encrypted with the first tenant encryption key to the first tenant; and encrypting the shared volume encryption key with a second tenant encryption key and providing the shared volume encryption key encrypted with the second tenant encryption key to the second tenant.

  • Deduplication-aware per-tenant encryption
    Patent number: 11403019
    Abstract: A method includes receiving a request to write a data block to a volume resident on a multi-tenant storage array, wherein the request is associated with a first tenant of the multi-tenant storage array, and determining whether the data block matches an existing data block on the multi-tenant storage array, wherein the existing block corresponds to a second tenant. In response to determining that the decrypted data block matches the existing data block: encrypting the existing data block with a shared volume encryption key; encrypting the shared volume encryption key with a first tenant encryption key and providing the shared volume encryption key encrypted with the first tenant encryption key to the first tenant; and encrypting the shared volume encryption key with a second tenant encryption key and providing the shared volume encryption key encrypted with the second tenant encryption key to the second tenant.
