Hi Damien,
What you wrote is correct in general. If a conventional and zoned LU are
combined, data is only written to the conventional LU once the zoned LU
is full. The data on the conventional LU may be migrated to the zoned LU
during garbage collection. This is why copying from the conventional LU
to the zoned LU is useful.
Jaegeuk, please correct me if I got this wrong.
Bart.
