Disk options for 4D/280 ?

[Robin Rohlicek]

I'm considering purchase of a 4D/240 or 4D/280 and need advice on disk
options.

I'm told that SGI only supports a single SCSI controller.  I'd like to
hang several disks (Wren V's) off the machine.  Are SCSI controllers
on the VME bus an option?

Any good options on third party SMD drives that are known to work?

(Also: Any options with 12" WORMS with support for something like a file
system on the disk?  What about the 5 1/4" eraseable variety? )

Any pointers would be appreciated,
					thanks.
