The Bottom Line

Cost savings and incresed ROI. That is the bottom line. Using Sun's UltraSPARC T1 processor, the T1000 and T2000 servers were compared to equivalent servers from thier competitors. When give the same computing task, the T1000 and T2000 averaged 70 watts of power consumption. The competition required 150 - 200 watts of power. Not only does the UltraSPARC T1 save money on computing costs, but can reduce the heat emissions that plague servers and will cost less to cool the server room itself.


  • Uses less than half the wattage of competing servers when performing the same tasks.
  • Energy efficiency requires less energy used on air conditioning to cool server rooms.
  • Drastic reduction in energy use also reduces carbon dioxide emissions.
  • Purchase price is comparatively low compared to similar servers.
  • CPU architechture is Open Source so developers can write tools and applications for the new system.


  • "Bleeding Edge," technology so people may fear implementing it.
  • No USB 2.0 ports.
  • Runs Solaris 10 or Linux. Microsoft users will require Terminal Services as well.


  • 2U design means more computing power in less storage space.
  • Sun claims that there are only 4,000 parts causing less heat output equalling a cooler server room.
  • Communications occur right on the chip. Less data travel means increased efficiency and performance.
  • Lower compute cycles to do the same amount of crypto operations.
  • Processes crypto operations using as little as 5% of CPU capacity compared with Xeon which uses 33%.
  • Traffic flow is increased due to minimal memory latency. This simplicity equals less energy use.

Guide Review - Energy Efficient IT

Sun Microsystems released its newest chip on the block, the UltraSPARC T1. The UltraSPARC makes use of multithreading technology (the ability to run more than one part or "thread" of a program at a time) having the ability to run four threads per core. Servers, such as the T1000 and T2000, using a processor with 8 cores can run up to 32 threads simultaneously. That's alot of computing power. Database servers, multimedia content servers, application servers, anything that runs labor intensive services, is going to be much happier running on this technology which Sun has termed CoolThreads Technology. The development of this new processor design, which is responsible for the reduction in energy use is Sun's response to the following findings regading datacenters:
  • 80% of all datacenters are constrained by heat and power;
  • Hardware heat load density has more than quadrupled over the past five years;
  • 40% need to upgrade their HVAC;
  • Over 50% of datacenters register above-average temperatures.
Businesses who choose to implement servers that make use of the CoolThreads Technology of the UltraSPARC T1 can expect top quality computing power, reduced energy bills, and a sticker price that doesn't offset the savings. In fact, the list price is comparable, and at times lower, than comparable servers using Intel or IBM processors.
