Storage and Disk Management Questions

This topic addresses design and operational management of storage subsystems and disk resources. Candidates should understand trade offs between performance redundancy and capacity, common redundancy and performance approaches such as mirroring striping and parity, selection of redundancy level based on workload, disk partitioning and logical volume management, file system considerations, storage tiering and data placement strategies, snapshotting and cloning, and how backups interact with live storage. Be prepared to discuss monitoring disk health and failure indicators, rebuild impact on performance, capacity planning, input output operations per second throughput and latency considerations, and security controls such as encryption and access restrictions.
