Which OCI component allows for high-performance shared storage in a compute cluster?

File Storage is the correct component that provides high-performance shared storage for a compute cluster within Oracle Cloud Infrastructure (OCI). This type of storage is designed to be accessed by multiple instances simultaneously, making it ideal for scenarios where different compute instances need to read from and write to the same files concurrently.

This shared access capability is particularly beneficial for applications that require collaboration between instances, such as big data analytics, web applications, and content management systems, where multiple compute resources need to access the same data set in real time. File Storage also supports standard file system protocols like NFS (Network File System), simplifying integration with existing applications.

In contrast, Block Storage is optimized for single-instance access and is typically used for databases or applications that require dedicated storage. Object Storage is designed for storing unstructured data like backups, media files, or large datasets but does not provide the shared access or performance characteristics required for a clustered environment. Meanwhile, Archive Storage is intended for long-term data retention and is not suitable for high-performance scenarios due to its low-access frequency and retrieval latency.

Thus, File Storage stands out as the best choice for providing high-performance shared storage in a compute cluster.
