container and mount a local storage

Hi all,

i have a question. if we have a hp dl380 server with 8 hdds. 1 or 2 hdds we use for proxmox and ct´s and the other 6 for a storage in raid5. how can we add the storage to the containers as storage space? for exsample: ct1 = storage folder test1 with 500gb space and ct2 = storage folder test2 ... with 100gb space? What do we must do on install to use 2 partitions for proxmox or what we must do here or configure in proxmox? or does it works only for vm´s? I hope you can give me informations. very thanks

regards
