The two compute nodes are relatively uncomplicated, as their primary filesystem is served over the network in a redundant fashion from the two masters. As such, their installation is relatively simple.
After physical installation, plug four 1G network connections into the first four network ports, and then into the first four ports (Labelled 1-4 above) on either Switch 2 or 3, as necessary. The exact order of these connections does not matter, just that the correct 4 ports are used on both ends.
Next, create a PXE boot USB stick. This can be done with a USB stick of larger than 128Mb that allows you to write to it on the block level, using, for example, dd or Win32DiskImager. Write the provided iso file onto the USB stick. You will need one per compute node. Insert these PXE boot USB sticks into any USB socket on the compute machines.
Now, to have a display, mouse and keyboard attached to the machine.
First make sure the auto startup is enabled: • Turn on the machine by pressing the ON/OFF button. • When the systems boots up, press F2 to enter the BIOS setup utility • Use the left/right keys to select the “power” tab • Use the up/down keys to select the “power on after power failure” and change this setting to “S0 – power On” press ENTER to select the setting • Press F10 to “Save and Exit”
Now, Get the MAC address of the first port on each compute node, and update the database to include these values into the compute A and compute B serial number values. During startup on the screen it displays the net1 interface. The number consists of 12 positions and should start with 78d0042xxxxxx - this should be in any included paperwork, but also the ipxe boot sticks will print this out to any attached screen when plugged in - the interface you want is net1. Compute A should be the one connected to Switch 2, and Compute B the one connected to Switch 3.
Lastly, boot the machines. They should automatically get their filesystem and begin processing.
