For a Scratch Filesystem (~3TB) in OCI, which storage option is recommended?

• A. DenseIO nodes with Local NVMe
• B. Standard storage volumes with high IOPS
• C. Object storage with lifecycle management
• D. Archive storage for less frequently accessed data

Answer: (A)

The recommended option for setting up a Scratch Filesystem of approximately 3TB in Oracle Cloud Infrastructure (OCI) would leverage Dense IO nodes with Local NVMe storage. This choice is ideal for temporary or scratch data that requires high performance and low latency access due to the speed of the NVMe technology. Dense IO nodes are designed with direct access to high-speed storage interfaces, making them suitable for workloads that involve processing large datasets quickly. Local NVMe storage provides significant advantages in terms of IOPS (Input/Output Operations Per Second) and throughput compared to traditional storage solutions, which is critically important for applications running in data-intensive environments. These characteristics align well with the needs of a Scratch Filesystem, where the primary requirement is to facilitate fast read/write operations during computations. In contrast, other options may not meet the performance requirements as effectively. Standard storage volumes, while providing high IOPS, might not match the speed of Local NVMe storage for temporary data workloads. Object storage with lifecycle management is typically better suited for data that is less frequently accessed and not tied to high-performance requirements. Finally, archive storage is intended for data that is infrequently accessed, which is not suitable for a Scratch Filesystem that requires rapid access and high throughput.
