sdaa, sdab, sdac, ... sdba, sdbb, sdbc.... etc etc.
and yes, if you have 40+ disks as JBOD, its a bloody mess, especially if
linux udev starts getting creative.
many of the systems I design get deployed in remote DCs and are
installed, managed and operated by local personnel where I have no clue
as to the levels of their skills, so its in my best interest to make the
procedures as simple and failsafe as possible. when faced with a wall
of 20 storage servers, each with 48 disks, good luck with finding that
20 digit alphanumeric serial number "3KT190V20000754280ED" ... uh HUH,
thats assuming all 960 disks got just the right sticker put on the
caddies. 'replace the drives with the red blinking lights' is much
simpler than 'figure out what /dev/sdac is on server 12'
