Western Digital Ultrastar Data102 SE4U102-102 4U Storage Enclosure

The Western Digital Ultrastar Data102 4U Storage Enclosure accommodates up to 102 drives for high-density enterprise storage. Its primary role is to house drives in large-scale data environments rather than act as a standalone storage drive. Support for configurations combining HDDs and SSDs allows the drive mix to reflect workload requirements. Capacity and performance can therefore be tailored through the choice of installed drives. The enclosure is designed for software-defined storage systems, where a high drive count is a central requirement.

The 4U format concentrates those drive bays into four rack units of vertical space. At 1047 mm deep, the enclosure requires attention to available installation depth when planning a deployment. Its width is 447 mm, while the specified physical height is 175 mm. These measurements are relevant when assessing the space available for a high-density storage installation. Intended users include enterprise storage operators, cloud service providers, and data integrators building large-scale storage infrastructure.

• SAS-3 interface support for compatible SAS drives.
• SATA-600 interface support for compatible SATA drives.
• Hot-swap support allows drive replacement without shutting down the enclosure.
• 24/7 operation support for continuously running storage environments.
• Internal storage enclosure design for integration into a larger storage system.
