This seems rather outdated and not clear on how to install CentOS via SuperMicro IPMI, so I thought I would make an answer of my own.
First, you need to check if your server is compatible with the operating system as on my own I had to backdown from Debian 7 to 6 due to ethernet driver issues. You can check if your SM server is compaitable via SuperMicro OS Charts or by contacting your host.
If it is, continue below, if it is not please check what is and use that.
You need to download the CentOS ISO by going to the website and downloading it directly to a folder on your computer. Once complete login into your IPMI control panel, below "Refresh preview" button, click and it shall open a Java Applet.
Now you need to go to Virtual Storage, select tab Device 1 (default). Also ISO from the list and select the ISO file from your computer. Once done, click Plug In then OK.
Reboot your server by going to Power -> Powerdown, then Powerup a minute after. Constantly keep hitting F11 (or whatever you need to hit from your BIOS your screen) and select VIRTUAL DISC, mine is called ATEN VIRTUAL DISC, and it should boot into your OS installation. It may take longer than usual as its communicating between your computer and the server since the ISO is located in your PC.
You may expect some freezes aswell, if you do, don't worry it will take some time, perhaps two hours depending on your options you select.
Once complete, REMEMBER to dismount the virtual storage unless you want to reinstall all over again.
