So our goal is to get a reasonable number of processors and "nodes" within a standard PC case. The reason for that is primarily because we will need to ship this unit around and also we want to build this for under $1000.
We were interested in trying out the Intel D945GSEJT for some other projects primary because of its integrated 12V DC power which saves us a few power converters. We are wondering after noticing its P4 style (ATX12V 2 x 2) if we could power a few boards from one standard power supply.
Well, they arrived and at the moment we have a very ugly configuration in process using two D945GSEJT and one MSI ITX board with dual interfaces we had lying around as a "head node".
But the kicker is all three boards are coming off the same Antec 300W power supply and only pulling what appears to be < 50W (note, I've got some 3.5" and 2.5" drives in the mix at the moment adding power, more detailed power specs shortly). Also forgive the clutter in these pictures. Mad scientist mode in play.
This shows the two boards being run from ATX12V cables. One is the standard such output that comes from the power supply. The other is converted from a standard 12V 4 pin molex cable (sample)
Here is a closeup of the 12V power for the board.
In the next posting I will discuss monitoring the 12V rails as I add some laptop drives to the equation and setup the "head node" for these two compute nodes.
Oh, and I also went to the hardware store to try to build some standoffs to "stack" these boards. More on that shortly.
