Western Digital Ultrastar Data102 SE4U102-102 816GB JBOD Storage Enclosure

The Western Digital Ultrastar Data102 JBOD storage enclosure accommodates up to 102 drives in a 4U rack-mount format. Its main characteristic is drive density, concentrating a large number of storage devices within four rack units. The enclosure is intended for enterprise and data-centre deployments rather than desktop storage. It provides a platform for large-scale storage infrastructure where drive count and rack space are key planning considerations. Server and rack-mounted storage systems are its stated application.

Host connectivity uses a Mini-SAS HD interface, making the host connection type an important compatibility check. The enclosure measures 1,047 mm deep, which is relevant when assessing available rack depth. Its width is 447 mm and its stated height is 175 mm. These measurements give the physical fit information alongside the rack-unit designation. For installation planning, both the enclosure footprint and the host interface should be checked against the intended rack and server infrastructure.

• 12 Gbit/s rated data transfer rate.
• Hot-swap support: allows supported drives to be replaced without powering down.
• 24/7 operation support: intended for continuous-use storage environments.
