24. SunRay Thin Clients Desktop runs on shared server > Gets PC out of the office > 10:1 – 50:1 SunRay to server ratio > No client upgrades! Operational carbon savings Potential for huge carbon savings by avoiding the PC upgrade cycle and associated manufacturing impact SunRay 2 ● 4 watts ● Windows, Linux or Solaris desktop ● Standard monitor, keyboard, mouse
