What two steps will help you design a high performance cluster in OCI as per the specified requirements?

Placing each of the nodes in one of the three different fault domains within a single availability domain (AD) is fundamental to designing a high-performance cluster in Oracle Cloud Infrastructure (OCI). This approach enhances fault tolerance by ensuring that if one fault domain experiences an issue, the other nodes in the cluster remain operational. By distributing the nodes across fault domains, workloads can continue to function without disruption, allowing for better resource utilization and minimizing downtime, which is critical for high-performance computing (HPC) applications.

This strategy leverages the distributed nature of the infrastructure, enhancing resilience and integrating smoothly with OCI's networking and storage capabilities. It optimizes performance as the communication latency between nodes can be reduced while still providing enhanced availability.

The other options do not align as closely with the goal of creating a high-performance cluster. For instance, deploying the cluster in a single AD with a shared file system may limit the overall redundancy and load-balancing benefits that come from utilizing fault domains. Deploying standby clusters in multiple ADs can be beneficial for disaster recovery but does not directly address performance optimization within a single cluster setup. Additionally, creating a backup of HPC node compute instances is an important operational aspect but does not contribute to the current performance and design requirements of the high-performance
