Depends on whether you want to boot from the SSD or not. If you'd want
to boot from it your only option probably is to get a SATA->SCSI bridge
like the ACARD AEC-7730A and hook it up to the on-board 53C876, the latter
will be a bottleneck though as it's just UW. It could be that Sun add-on
cards like the 375-3191 which is U320 and supported by mpt(4) have their
own FCode which would also allow to boot from an SSD connected via a
SATA->SCSI bridge to it.
If booting from the SSD isn't required you can just put in some SAS
controller supported by mpt(4) and directly connect a SATA SSD to it.
There are also some PC-world SATA controllers which work in sun4u
machines (check the archive for at least a working Marvell one).
Generally there also are SATA add-on controllers which rely on their
BIOS to be executed even when not booting off of them, which isn't
the case in a sun4u machine.
