Western Digital 1ES2155 Western Digital Ultrastar 1ES2155

The Ultrastar Data102 storage platform is a key element of next-generation disaggregated storage and Software-Defined Storage (SDS) systems. The Ultrastar Data102 provides up to 2PB1 of raw storage in 4U using our 20TB SMR HDDs in a compact and efficient form factor. The Ultrastar Data102 addresses the demanding storage needs of large enterprise customers, storage OEMs, cloud service providers, as well as resellers/integrators requiring dense, shared HDD.

IsoVibe� Vibration Isolation Technology
Precise cuts in the baseboard provide a suspension for the drives in the chassis, isolating them from transmitted vibration. The result is that consistent performance is maintained, even when all the drives are working hard.

ArcticFlow� Thermal Zone Cooling Technology
By introducing cool air into the center of the chassis, drives operate at lower and more consistent temperatures than conventional systems. This results in lower fan speeds, reduced vibration, lower power consumption, quieter operation and ultimately higher reliability.

Western Digital Resource Manager
A GUI-based tool that enables real-time monitoring and management of the platform and provides a consolidated dashboard displaying the most critical information. Other views allow platform configuration, health monitoring, and maintenance.
