There is a SAS card that works on UltraSPARC, just not in the U5/U10.
Certain LSI cards, such as the 3800X will work in numerous other
UltraSPARC machines such as the U80.  It requires a 3.3V slot while the
U5/U10 are 5V.

The T1000 and T2000 use a LSI chip I believe.

And yet people have made SPARC drivers for various NICs and soundcards,
and people using Solaris 10/SPARC for workstations is probably even more
of a minority compared to the people who could use SATA.

Still, I'm sure that is part of the reason.

Brian Hechinger has SATA in a U80 using the LSI SAS controller that
won't work in a U5/U10.
