Nutanix’s patented unified namespace technique allows coherent access to unstructured data across different protocols on a storage system. Metadata changes are processed natively by protocol stacks, stored in a metadata store, and transferred between storage services via a message bus, ensuring semantic equivalence in data access.

Unified namespace technique for coherent access to unstructured data
A recently granted patent (Publication Number: US12014085B2) discloses a computer-readable medium containing program instructions designed to facilitate the processing of metadata changes related to data access requests within a storage system. The program instructions enable the coalescing of metadata changes for transfer between different storage services, ensuring that data access remains consistent across protocols. By translating metadata changes according to specific semantics, the method ensures seamless access to data stored within a common data store without the need for data replication. Additionally, the system utilizes a message bus for efficient communication between storage services, supporting event notifications, recovery, and replay functionalities in case of failures.
Furthermore, the patent describes a method and apparatus for implementing the aforementioned process within a storage system. The apparatus includes two storage systems, each executing specific program instructions to process and translate metadata changes for maintaining data consistency across different data access protocols. The method involves notifying the target protocol stack of the second storage service about the coalesced metadata changes, ensuring that access to data remains semantically equivalent regardless of the protocol used. The system also leverages the message bus for logging and replaying metadata changes, enhancing system reliability and consistency. Overall, the patented technology aims to streamline data access operations within storage systems, promoting interoperability and efficiency across different data access protocols such as network-attached storage (NAS) and simple storage service (S3).
