Which are recommended storage options on OCI for a Persistent Filesystem of approximately 3TB?

The recommended storage options for a Persistent Filesystem of approximately 3TB on Oracle Cloud Infrastructure (OCI) are Block Volume and File Storage Service (FSS). Block Volume is ideal for applications that require high performance and consistent low-latency access to data, making it suitable for databases and enterprise applications. It allows attaching to compute instances and provides the flexibility of resizing volumes.

File Storage Service (FSS), on the other hand, is designed for use cases that require scalable and shared file systems. It provides managed file shares that can be accessed by multiple instances and offers performance levels that make it appropriate for workloads that involve large data sets or require high throughput. The combination of Block Volume and FSS covers both high-performance needs and scalable storage requirements effectively.

In contrast, options like Local NVMe, while offering high performance, are not suitable for persistent storage across instance lifecycles and may lead to data loss if the instance is stopped or terminated. Archive storage and Object Storage are designed for infrequently accessed data and are not optimized for performance-intensive applications. Cold Storage is also geared more towards archiving rather than providing the performance and access capabilities needed for a persistent filesystem. Thus, B is the most suitable choice, providing the necessary balance of performance,
