My Happy (and Quiet!) Little Netra T2000
By jhawk on Dec 06, 2005
The last month, I've been running tests on Niagara-based systems. Every time I walk into our Communications Lab here at Sun, it sounds like I'm walking into a wind machine. All these fans roaring in their efforts to draw in air to wash over CPUs to cool them down. The sounds is quite loud
One of the really striking things about walking into our labs now is that there is a quiet spot on two racks. These two racks contain my two Onterio Niagara boxes(recently named Netra T2000.
Notice how small these things are. In this picture, we are using an old Ultra60 as a shelf.
Compare the fan sizes on the back. These fans are tiny.
Remember noise is energy.. if so.. these Niagara boxes are not drawing much power. There isn't as much need to have big fans to cool down giant power hungry CPUs.
To contrast this.. I recently gave a presentation at our Sun Software Summit. In the back of the room (behind the audience) was an old v60z which is based on Intel Xeon. We had borrowed this box to run some Solaris x86 demos of our Messaging Server. The noise levels of this box was so loud, I couldn't hear half of the questions from the audience.
