More than one Sun on a SCSI bus

[beowulf!bownesrm at crdgw1.ge.com]

Has anyone out there tried to get more than one Sun to share a SCSI disk
for data only? I realize it won't boot this way, but it would be usefull
to me to be able to share a disk between one or two machines for data.
Certainly better than pumping the bits out over an ethernet where they
have to contend with 100 other machines...
