The creator of marTux ( Martin Bochnig ) issued a usenet post some time ago
about the IDE controller drivers in Solaris and its an excellent little
document to refer to.
Let me copy it out in its entirety here.

Only true for Solaris8_FCS/Update1/Update2's limits (at least on x86).
The device driver (and therefore Solaris) version you use is just a
"soft-limitation", true.
BUT the 128GB bug is hardware related (with rare exceptions, i.e.
CMD/Sil0 649, where it is kind of "hybrid limit" [UNDOCUMENTED]).
I guess Solaris 10 is fine. Anything

THOMAS GLANZMANN, WRONG!
It depends on the builtin (IDE-Controller-) chipset.
Several older chipsets of various vendors including CMD/Sil had their
hardwired HARDWARE limit at 128GB.
In those cases even "Solaris 18", maybe in 2018, wouldn't help at all.
Guess-work is of no help, but here are FACTS:
bash-3.00$ uname -a
SunOS unknown 5.11 smb_1__20050731sun sun4u sparc SUNW,Sun-Blade-1000
bash-3.00$ isainfo -v
64-bit sparcv9 applications
vis2 vis
32-bit sparc applications
vis2 vis v8plus div32 mul32
bash-3.00$ grep -i ata /etc/driver_aliases
uata "pci1095,646"
uata "pci10b9,5229"
uata "pci1095,649"
uata "pci1095,680"
bash-3.00$
You see ALL IDE-chipsets currently supported (or at least "just
working") on SPARC Solaris2.11_nv18 (OpenSolaris Nevada build 18
[Solaris11 from July]).
The CMD 646 is slow crap (used in U5/U10 and maybe others).
The CMD/Sil (0)649 is not built into any SUN system I am currently aware
of. However, it has been a very very good solution for ca. three years,
as it was the ONLY one also available in form of IDE-PCI boards (instead
of system board - integrated ONLY) AND working on SPARC Solaris hosts.
It was quite fast with Solaris([8/]9/)10's default ata driver (UDMA100).
uata "pci10b9,5229" represents the "Ali 5229 PCI Bus Master IDE Controller".
There are many UltraSPARC systems employing it (mainboard integrated):
SB100/SB150/SB1500/SB1500Silver(?)/Tadpole_SPARCle_500SX and certainly
low-end servers as well as ide-based TelCo's (including yours?!!).
I'm pretty sure it is hard-limited to 128GB (not 100.00% sure).
It all depends on access mode/addressing issues.
YOUR SOLUTION is the ultracheap (starting at $9 on eBay) CMD/Sil 0680
Dual Channel pci-board!!!
It will support >= 128GB (at least 500GB). It is very fast
(UDMA/UATA_133). You can have as many of them as you have free pci
slots. You can use them with volume manager/raid.
etc. etc., all you ever dreamt of!
YEZ, also on any NON-IDE (SCSI based) SUN SPARC machine (without boot
support then).

======================================================
ya gotta love him for "Guess-work is of no help, but here are FACTS".
:-)
So, there ya go. Go get a Dual Channel pci-board CMD/Sil 0680 and your
rocking and rolling.
