A storage solution designed to hold multiple hard drives within a computer case or server, this device typically consists of a metal frame with individually numbered slots or bays. Each bay accommodates a tray or caddy where a hard drive is securely mounted. This organized arrangement facilitates easy insertion, removal, and replacement of storage devices.
This type of organization streamlines cable management, improves airflow around components, and maximizes space utilization within the computer chassis. It’s particularly valuable in server environments where numerous drives are often required. Historically, as drive sizes decreased and storage capacities increased, these solutions became essential for managing higher densities of drives within limited physical space. This improved accessibility significantly impacted server maintenance and upgrade procedures.
