What is primarily focused on with Fault Domains?

Fault domains are primarily focused on isolating infrastructure failures within a system. This concept is essential for ensuring high availability and reliability in storage solutions. By segmenting the infrastructure into distinct fault domains, organizations can prevent a failure in one domain from affecting others. This isolation can involve grouping resources such as servers, storage devices, or network components, so that if one part encounters issues, the other parts can still operate effectively. This design enhances the resilience of the system and minimizes the potential impact of failures, ultimately leading to improved system uptime and data availability.

The other choices, while relevant in the broader context of infrastructure management, do not capture the primary goal of fault domains. They may contribute to operational efficiencies or performance improvements but do not address the central purpose of isolating and managing potential failures.
