The Lenovo ThinkSystem DE4200H is a dense, high-capacity storage enclosure designed for data centers that need to pack a lot of drives into a small space. It holds up to 24 large-form-factor hard drives in a 4U chassis, making it useful for backup, archiving, or any workload that demands huge capacity without high performance. The build is modular, with hot-swappable drives and redundant power supplies for reliability, though it lacks the flash storage acceleration found in some hybrid arrays.
