i have HP dl360p gen8 server with 8x600gb sas 10k hdds. Can you please recomend me raid setup for best/optimal preformance of proxmox. and if possible to have 1 disk in spare.
with 8 drives and assuming you have a P420i controller installed, Raid6+0 is probably for best bet. Will give you (6 x 600) capacity and the tolerance of up to two failed drives
