High Density – Up to 102 HGST HelioSeal® HDDs providing up to 1.2PB of raw storage in a 4U enclosure

Flexible – Choice of SAS or SATA and up to 24 slots can be populated with SSDs for a data acceleration tier

Innovative – Patented IsoVibe™ and ArcticFlow™ technologies improve performance and cooling

Designed for High Density and Flexibility
The Ultrastar Data102 is a key element of next-generation disaggregated storage and software-defined storage (SDS) systems, delivering high density and the flexibility to balance performance with cost. The Ultrastar Data102 provides up to 1.2PB1 of raw storage in a compact and efficient form factor. HGST HelioSeal® drives ensure cool running, quiet operation and high reliability. A high performance data tier can be set up for demanding applications by using SSDs in up to 24 of the drive slots.

Building on 50+ years of Storage Design Experience
Conventional dense disk shelves frequently suffer from performance degradation due to induced vibration from adjacent drives. Traditional platforms also have cooling challenges as the cooling air passes over successive rows of drives, losing effectiveness as it gets heated up along the airflow path. Developing storage devices and platforms side-by-side, we address these challenges through vertical innovation, a set of technologies developed based on a holistic view of devices, platform, and their interactions. The first two of these patented technologies are IsoVibe™ and ArcticFlow™. IsoVibe reduces vibration-induced performance degradation, while ArcticFlow overcomes the cooling issues by introducing cool air into the middle of the platform. Both these technologies contribute to long-term reliability, enabling our five-year limited warranty on the entire platform.

Designed for the Enterprise and the Cloud:
This new platform addresses the demanding storage needs of large enterprise customers, storage OEMs, cloud service providers and resellers/integrators that require dense, shared HDD or hybrid storage. The Ultrastar Data102 provides the flexibility to specify the HDD and SSD combinations to balance capacity, performance and cost.

IsoVibe Patented 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.

Arctic Flow Patented 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
