The SCSI setup on our sd box (well, part of it) is like this:
sym0: <825> rev 0x2 at pci 0000:00:0a.0 irq 10
sym0: No NVRAM, ID 7, Fast-10, SE, parity checking
sym0: SCSI BUS has been reset.
scsi0 : sym-2.1.18n
Vendor: TANDBERG Model: DLT8000 Rev: 0255
Type: Sequential-Access ANSI SCSI revision: 02
target0:0:2: Beginning Domain Validation
sym0:2: wide asynchronous.
target0:0:2: Domain Validation skipping write tests
sym0:2: FAST-10 WIDE SCSI 20.0 MB/s ST (100.0 ns, offset 8)
target0:0:2: Ending Domain Validation
scsi1 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36
<Adaptec (Compaq OEM) 29160 Ultra160 SCSI adapter>
aic7892: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs

Attached scsi tape st2 at scsi1, channel 0, id 3, lun 0
st2: try direct i/o: yes (alignment 512 B), max page reachable by HBA 1048575
Neither SCSI chipset has given us any problems, although we don't
exactly push them hard (the box can't!):

Lowest spec production sd out there, perhaps? :)
