Old Docs

Cinder uses iSCSI to export storage volumes from multiple storage nodes. These iSCSI exports are attached (using libvirt) directly to running instances.

Cinder volumes are exported over the primary system VLAN (usually VLAN 1), and not over individual VLANs.

The underlying volumes by default are LVM logical volumes, created on demand within a single large volume group.
