afaik, The only way to achieve > 15 "partitions" per disk with /dev/sd* is
to
use device mapper. I'm not sure the upper limit of logical volumes
per PV, but I'm fairly sure it's higher than 15.
You can also use GPT (GUID Partition Table) for non-boot disks (or
for all disks at ia64/s390). If I good remember the number of
partitions is unlimited by GPT specification (= the limit depends on
implementation; usually 128 partitions). The 'parted' supports GPT.
