PCI width or driver width?
Jochen addressed the software side.
The PCI "bitwidth" refers to the connection to the bus. Since the Ultra
10 uses 32-bit PCI you'll have no benefit from a 64-bit card. The
drivers are OS dependent, if you have one that works with your Solaris
you don't have to worry about the kernel architecture (64-bit vs
If you had a newer machine with 64-bit PCI then you'd see an advantage
in a 64-bit wide card. In general, unless you're programming your own
drivers, don't worry too much about the bit size. All decent
architectures deal gracefully with 32-64 issues (except Alpha which
doesn't need to worry).
