Soheil,
I took the liberty to add the openstack distribution list back in.
Your description is a bit vague. Do you have dedicated nodes for
storage, or do you run instances on the same nodes where storage is
configured? Do you want run use volumes for instance storage, or
ephemeral disks?
OpenStack stores volumes wherever you configure it to store them. On a
disk array, an NFS server, a Ceph cluster, a dedicated storage node, a
controller or even a compute node. And more.
My guess: Volumes on controllers or compute nodes are not a good
solution for production systems.

Hi,
My question is does OpenStack store volumes somewhere other than
the compute node?
For example in PackStack on two nodes, one for controller and network and
the other for compute node, the instance's volumes will be stored on the
controller or on compute?
