We are working on doing that now. There are a few problems to note:
* Most IPI disks cannot run that much faster than better SMD drives
(3.0MB/sec)
* Sun's IPI interface is a two board set and will not fit in a 330
* Early 330's had a smallish powersupply and you have to be careful about
how much you're drawing out.
* I have not been able to determine just how the CPU board knows that there
is a SMD/SMD-clone board in there to boot off.
I would say to buy a 370 for the slots and powersupply and put your own
SMD or IPI if you wish. IPI is pretty new and not established enough to
support the end-user who is playing system integrator too.
Most of the big names in disk controllers (Xylogic, Interface, etc) have
beta boards to do what you're talking about. I don't think any are
released solid products.
