as I mentioned, vendors don't seem to bother rewriting third-party
disk controller bioses to enforce brand lock-in.
for instance, most 1U's with 1-4 SATA will drive those bays from the
AMD/Intel chipset controller, and so not be crippled. supporting SAS
or hardware raid5/6 in those slots would also be a tip-off that a
"higher end" controller is in use (which means "less functional"
and "non-conforming" in this context.)

well, those would be SCSI and FC drives, where vendors seem to be
more timid in doing nonconformity-for-lock-in. I guess they figure
that if you're going to pay for gold-plated drives, you'll probably
buy them from the original vendor. the lock-in is focused on more
commoditized drives, where the vendor typically charges a >100%
premium to relabel a generic drive from wd/seagate/etc.
