In order to naturally support multi-target instances on an Open-Channel SSD, targets should own the LUNs they get blocks from and manage provisioning internally. This is done in several steps. Since targets own the LUNs the are instantiated on top of and manage the free block list internally, there is no need for a LUN abstraction in the media manager. LUNs are intrinsically managed as in the physical layout (ch:0,lun:0, ..., ch:0,lun:n, ch:1,lun:0, ch:1,lun:n, ..., ch:m,lun:0, ch:m,lun:n) and given to the targets based on the target creation ioctl. This simplifies LUN management and clears the path for a partition manager to sit directly underneath LightNVM targets.
