Energy Efficient Data Storage Systems by Atrato, Inc.
these environments. Atrato has developed a data storage system that exploits the low power characteristics of 2.5-inch disk drive technology that allows for:
- Ultra-high-density packaging: 160 disk drives per 3U enclosure
- Extremely low power consumption: 450 watts idle, 750 watts 100% active
- Minimal cooling: ~5°C thermal gradient front to back
This novel approach to...
