Ultrastar Data 102

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.

Overview

Designed for Extreme Density

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.
