Twin Dragon
Two independent servers in a 1U platform

Twin Dragon Introduction

The ITOX Twin Dragon 1U rackmount platform contains two advanced motherboards, each with its own 3.5" drive bay and Ethernet LAN controller. Two Twin Dragons can fit back-to-back--enabling 4 servers to fit in a single 1U space and 168 servers in a 42U rack. The Twin Dragon is available as a barebones platform (case, power supply, and motherboards) or a full system including your choice of CPU, memory, hard drive and operating system.

Twin Dragon Features

  • Innovative case. The Twin Dragon case design allows two motherboards in a case. Two cases can be mounted back to back for a total of 4 servers in 1U rack space. To make this possible the motherboard uses the compact EBX size, the same length and width as a 5.25" drive.
  • Powerful motherboard. The CS15 motherboard supports front side bus speeds to 133 MHz, memory to 512 MB, an Ethernet controller, on-board video, and Intel Pentium III and Celeron motherboards.
  • Advanced system cooling. Two 75mm blowers produce more than 26 CFM air-flow. This highly effective cooling permits operation at ambient temperatures of 45 degrees Celsius. The CS15 motherboard monitors processor temperature and fan operation and triggers alarms if operational limits are exceeded.
  • Two 3.5 inch drive bays. Each motherboard may operate as an independent system with its own dedicated hard drive.
  • Watchdog timer. The CS15's configurable watchdog timer resets the system and restarts software in case noise spikes or other events cause runaway software to hang the system. This is a valuable tool which maintains control when continuing and dependable operation is critical.


Benefits
  • Feature-rich. In addition to the system capabilities listed above, each Twin Dragon includes keyboard/video/mouse (KVM) ports, two USB ports, and one DB-9 serial port. A COM2 header is available internally on the motherboard.
  • Reliability. The system offers excellent MTBF ratings and FCC/UL/CE environmental and regulatory certifications. The complete Twin Dragon system is backed by ITOX's 2-Year Limited Product Warranty.
  • Compatibility. The CS15 motherboard runs Microsoft, Linux, and all standard x86 operating systems.
  • Flexibility. The CS15 may be controlled in several ways including via keyboard, mouse, video, LAN, and console redirection.
  • Extended life cycle. The CS15's long-term availability is prolonged because ITOX has defined this motherboard as one of its revision controlled products. Users benefit by avoiding costly computer design changes and system re-certifications.


Applications

  • Web servers. The Twin Dragon is cost-effective in data centers because it permits either two or four servers in a 1U space--up to 168 servers in a 42U rack. On-board Ethernet, rackmount form-factor, and low cost of ownership make the Twin Dragon an attractive solution for many ISPs and ASPs.
  • Clustered computing. Fit up to 168 servers in a 42U electronics rack for multiple computer applications to reduce overall system.
  • eCommerce. The high-performance Twin Dragon supports high-traffic and high load applications.The high-performance Twin Dragon supports high-traffic and high load applications.
