A cold-air bypass apparatus may include (1) a mount configured to couple the cold-air bypass apparatus to a drive-plane board housed within a storage-system chassis and (2) a baffle configured to direct a portion of an airflow through an opening in the drive-plane board from below the drive-plane board to above the drive-plane board. The drive-plane board may include (1) a front drive section that includes storage-drive connectors coupled to the drive-plane board, (2) a rear drive section that includes additional storage-drive connectors coupled to the drive-plane board, and (3) the opening located between the front drive section and the rear drive section that allows air to flow from below the drive-plane board to above the drive-plane board. Various other apparatus, systems, and methods for directing air in a storage-system chassis are also disclosed.
