I have node with 5HDD striped, motherboard cant make raid 10 and windows also.
then it will be very good to get posibility to install multi nodes to 1 pc, 1 for each hdd.
it will bring more relible situation, in case if hdd broken, will be only 1hdd data lost not all.
Smoller posibility to database breake and data lost. I have made 2 nodes on 1 pc, but, i had to install second node service manualy. works fine
