Does IDs from `ls -l /dev/disk/by-id` output are unique to a disk? - DELL PERC card

The World Wide Name is expected to be globally unique, and barring mistakes by a drive manufacturer it should be.

However, in the case of the single-disk RAID0 on your ancient PERC card, which was how people worked around its lack of JBOD support, the WWN refers to the virtual RAID0 disk, not to the physical disk. (And global uniqueness might not be possible, but they will at least be unique on your controller.) This should not cause you a problem in practice, but if it does, then buy a different HBA that supports JBOD.
