Western Digital HGST Ultrastar Data102 SE4U102-102 816TB Storage Enclosure

The Western Digital HGST Ultrastar Data102 816TB storage enclosure provides 816 TB of listed capacity for enterprise storage. It supports up to 102 drives within a single enclosure. That drive count makes high-density storage its defining characteristic, bringing many drive positions together rather than spreading them across separate enclosures. The product is intended for server and data centre environments. Its stated workload focus is data-intensive enterprise storage, with capacity and drive density central to its role.

SATA and Mini-SAS HD are the listed interfaces for this enclosure. SATA is relevant to drive connectivity when assessing the intended storage configuration. Mini-SAS HD is the other connection type to account for when planning integration with server equipment. The chassis uses a rack-mount design rather than a freestanding desktop format. Its 4U format specifies the vertical rack space required, making rack allocation an important consideration alongside the storage connections.

• Hot-swappable drives: drives can be replaced without shutting down the system.
• Rotational vibration sensors: included in the listed specification.
• 447 mm width: a chassis measurement to check against the intended installation.
• 175 mm height: the enclosure's stated physical height.
• 1047 mm depth: a relevant measurement when checking rack depth and available clearance.
