So this might be an obvious question, but I am managing several servers over a network and I would like to be able to find out what type of connector each server is using (i.e. SATA, SCSI, IDE, etc...) without powering off the machine and looking inside physically.

I have tried to use `smartctl --scan` and it seems accurate for the most part, however when I use it on my Lenovo Thinkpad, it prints:

`/dev/sda -d scsi # /dev/sda, SCSI device`

which I kind of doubt that my laptop has a SCSI device. Any ideas on how I could verify this information without opening the servers themselves?
