there is indeed. You could try if you can put a bare minimum OS on
one disk and build a logical volume on the other disks that you use
to store your $HOME or /usr/local or whatever on.
I have such a setup on an Indigo (I admit it's running an older
version of 6.5) with 3 1GB disks (*cough*). The first disk includes
the base OS, the other 2 are striped together as a single volume
that is mounted as /storage. I have some application stuff there
with /usr/local actually being a symlink to the application dir on
the storage volume.
On Crimsons this is even better in terms of making good use of I/O
bandwidth as you have 2 SCSI controllers you can place the drives
on, which can give you additional bandwidth during accesses. I have
some notes on setting up the SCSI buses on my Crimson page. It's
actually just a matter of terminating the buses below the drivebays
and attaching the SCSI cable that dangles down from the top of the
cardcage to your IO3B board - if the system isn't already set up

Bad news: I never bothered too much with programming issues, but I
think the first big iron graphics option with hardware support for
Open GL is the Reality Engine. OGL still should work, with quite
some performance penalty for running it on IRIS GL hardware. I hope
I'm not mixing things up here...

*That* indeed sounds like an adventure.

I always used various Plextor drives (including 32x UltraPlex).
These have a jumper for setting the blocksize to 512b. It might not
be neccessary to do so, in any case it doesn't hurt.

Then 6.2 is ok for you. As for installing 6.2 on a Crimson I can't
recall any specific problems. Maybe that was because mine always
used disks that were used with 5.3 before.
May I talk you into doing some test when you have one of them up and
running? I'd be interested how VGXT performs in comparison to VGX. I
have been hunting for VGXT Raster Manager boards quite a while, but
so far I came up with nothing.
