CloudRack C2 Trays

Cool, Clean and Efficient

CloudRack C2 is a unified cabinet that combines extreme densities with break through energy efficiency for cluster computing. CloudRack C2 delivers dramatic bottom-line savings by eliminating "stranded power" (a data center’s power capacity which is paid for, but ultimately unused). It assures maximum power usage, cooling efficiency, and staggering server densities with up to 1,280 cores per cabinet. CloudRack C2 capitalizes on an ultra-efficient, rack-centric Eco-logical™ design which uses fan-less and cover-less 1U server trays installed in 24 inch wide 23U and 46U intelligent cabinet configurations.

The Power XE™ Difference

CloudRack C2 is the first of many Rackable products to utilize Power XE — a next generation cabinet-level power distribution technology:

• Virtually eliminates the data center "stranded power" problem (a data center’s power capacity which is paid for, but ultimately unused) and provides nearly perfect phase balancing


• Significantly improves power delivery efficiency by converting incoming AC power to 99 percent efficient 12V DC power via hot-pluggable, N+1 redundant rectifiers


• Eliminates server-level power supplies and cooling fans for improved reliability

Dramatic Thermal Efficiency

CloudRack C2 is thermally optimized to allow data centers to operate at much higher temperatures, up to 40° C (104° F).

• Higher system temperature tolerance means significantly reduced power consumption by Computer Room Air Conditioning (CRAC) units which in turn means radically reduced operating cost.


• Thermally managed airflow via redundant, hot swappable, easily serviceable, cabinet-level autonomic fan arrays for better enclosure reliability


• Over 80% reduction of fan power compared to conventional AC enclosures

Build to Order Optimization

Rackable’s BTO processes assure CloudRack C2 systems are tailored to your cluster computing environment and optimized to support your specific computing applications. CloudRack C2 cabinets are available with MicroSlice™ architecture-based server trays for improved price/performance. They are built ready to take advantage of next generation AMD and Intel designs for better performance, energy efficiency, and virtualization capabilities. CloudRack C2 systems are rigorously tested then shipped to your data center floor, ready for immediate integration.
