This cable takes 1 SATA power and expands it into 4. We need one of these per PSU cable, which would allow for up to 6 HDD/SSD to be powered with each cable from the PSU.

These cables allow for the LSI 9201-16e to connect to your HDD/SSD in the DAS directly. You simply need to feed the cables through the Rosewill's I/O shield slot, where the motherboard would go. The cables should be plenty long enough if you have the two servers stacked right on top of each other.

We need these to plug in the Arctic 120mm and 80mm PWM fans (listed below). One two-pack is enough for the DAS setup.

This is what we need to turn the PSU on. This allows us to use the PSU's power switch on the back of the power supply to turn the whole unit on and off. Turn on the DAS before you turn on your main server, and turn off the DAS after turning off your main server.
