As others have said, you need 80 pin disks. If they are non-Sun,
Solaris is likely to complain they are not-labeled. Run format and
label the disk.

You need a carrier to hold the disk. The machine will take two disks,
but for reasons of heat I would limit that to one if I were you,
especially if there are multiple processors or fast processors. Heat
is the biggest bugbear of that machine. Some models have no fan close
to the disk. Some models have a very small fan. I would be tempted to
not bother having a CD and fit a larger fan.
