UPDATE: cluster is working, but i need install mpich2 and some thiings and program it. I had a problem with static ips now and i thinkin of better energy source.

Hi, I want to build cluster with ubuntu for my bioinformatics calculations and maybe for webserver. I didn't do anything like that earlier, so I want you all to be kind xD Here is what i have: > 5x orange pi one plus (every opi with heatsinks) > NAS expansion (for disk minissd or HDD) > tp-link switch with 8 ports (tp-link tl-sf1008d, im afraid it will be to slow for this, but i can change it later) > AC DC Power Adapter 5V / 10A Charger Transformer ( for Opi's) - with splitter > 2 port usb charger for NAS and switch (cause of i cant find power supply for all of opis with switch and NAS - im bad at electronics) > ethernet cables > Adapters to power supply Photo: https://ibb.co/iWkOOc I have some questions about - sd cards, every opi must have ubuntu server installed? - NAS when i connect expansion with disk will it be visible to system without any actions in sys? - can i use ubuntu desktop? or it must be ubuntu sesver OS?
