What design consideration is typical in a server?

In server design, having extra copies of many components to enhance fault tolerance is a common and critical consideration. This approach minimizes the risk of downtime and data loss by ensuring that if one component fails, another can take its place without interrupting service. For example, servers might be equipped with redundant power supplies, hard drives configured in RAID (Redundant Array of Independent Disks) setups, or multiple network connections. This redundancy is essential in critical environments, where reliability is paramount.

The concept of fault tolerance is crucial, especially for servers that host websites, databases, or critical applications. By incorporating redundancy, organizations can maintain continuous operation and provide better service to end-users. This design philosophy aligns with best practices in IT infrastructure, where uptime and data integrity are vital.
