You'll find that SCSI clustering is restricted to Alphas only. For the

My own personal experience with DSSI was not altogether exciting. We'd
purchased two 3400 hundreds to replace an 11/785 and an 11/780. The 3400s
never seemed as fast. Eventually, the 3400s were replaced with an ethernet
cluster consisting of a DEC3000-300, an 11/785 and an 11/780 and the old
VAXes were much faster.....

On an unrelated
note I think I have enough bits to set up a pair of VS (as
in VAXServer) 3400s as a VMS cluster! Since these things will cluster over
DSSI it should be pretty neat. If I get it running I'll see if I can put it
on the net for login access. That should be an interesting exercise!

I've threatened to do a SCSI cluster, but never found the time. If you're
going to do that, you'll need to set up TCPIP so that the two systems
appear as one, so if one goes down you can still get to the cluster!
That's something else I've not found enough time to try. As for putting
them up on the net, all you need is the connection to the net.
