SGI's Eco-Logical™ servers and
storage are designed to reduce power consumption and increase system-level efficiency
and reliability. Leveraging low wattage components with high Mean Time Between
Failure (MTBF) ratings — with careful focus on the power supply in a given
system — is an important design criteria. Available with both high efficiency
Alternating Current (AC) and Direct Current (DC) power supplies, SGI
servers and storage systems feature a broad range of power distribution options
compatible with any data center design:
High Efficiency AC Deployments
- Our high efficiency AC rack level solutions feature servers and storage
systems leveraging our custom, high value AC power supplies compatible
with all standard data center environments.
Rectified AC-to-DC Power
- Launched in 2003, our award-winning Rectified
AC-to-DC rack-level designs enable the conversion of standard data
center AC input power to -48VDC within the rack itself, providing each
DC-based system with high efficiency coupled with the superior reliability
equivalent to most redundant AC designs. Our easiest and most popular
DC deployment option, Rectified AC-to-DC Racks can be deployed in any
AC-based data center with no infrastructure changes required.
- Applying our rectification technology to an entire data center row,
Rectifier Cabinet technology further consolidates AC-DC rectification,
yielding additional gains in reliability and availability.
Direct DC Power Solutions
- DC-based data centers (such
as legacy telco environments) can experience immediate power savings
delivering DC input power directly to SGI -48VDC based
servers and storage.
- AC-based data centers have the option to deploy a sophisticated data
center wide high voltage rectification module from SGI partner
Validus, essentially transforming a legacy AC data center into a DC-based
data center while eliminating costly AC infrastructure.
Each of SGI power distribution techniques — whether
a traditional AC design or one of our patented DC technologies — can alleviate
the heat generation and power efficiency challenges that burden data center
operators today, while increasing reliability and overall operational cost savings.
