The real Sun X6540A (*) adapters are available for very little these days
and have internal connectors.  They are only 40MB/s but work perfectly.
The drive can sit where the IDE drive would normally sit.  You can also do
the same in a Blade 100/150, although it's a bit fiddly to get the SCSI
cables routed through to the disks.

Thanks,

(*) Make sure you get the single-ended X6540A (375-0005) card, and not the
(almost identical) differential X6541A (375-0006) card.
