In servers its a scsi cd-rom

In workstations its ide.

I know of no exceptions to the server rule.

There may be exceptions to the workstation rule.

It is possible to install a scsi cd in a workstation so long as the proper scsi card is also installed.

Normally they are single ended SCSI. The K series as well as the D's, R's all have internal SE interfaces to drive them. The L servers (RP) also have single ended but in those devices they are normally DVD ROM's
hope this helps

I have no idea.

I firmly remember stating emphatically that they don't support IDE and being proven wrong.

If I have a slow day, I'll look up the thread.

It could be unreliable memory you know....(taps the old forehead)

Every workstation I've actually taken apart was ....

SCSI

To get back to the original question, then, I guess it might be fair to say that workstations could be either, but generally they're SCSI:

root# lssf /dev/rdsk/c2t2d0
sdisk card instance 2 SCSI target 2 SCSI LUN 0 section 0 at address 8/16/5.2.0 /
dev/rdsk/c2t2d0
root# model
9000/785/C360
