I'll never forget 'logging into' my hdds for the first time. :) DSSI is just plain neat. If I remember correctly the drives themselves speak enough MSCP to service cluster requests themselves. -brian On Dec 21, 2011, at 22:59, "Bob Armstrong" <bob at jfcl.com> wrote: DSSI! Brian, excuse me, but you're nuts :-) What's wrong with DSSI? I've got a uVAX-III with a farm of DSSI drives (the DEC R-400X box) in the garage. DSSI drives are cool - T11 CPUs in each one, running RSX-11S (Johnny should love that!). They even have a little MCR that you can talk to... BTW, if anybody has a DSSI DLT drive (e.g. a TFxx) that they're willing to part with, let me know. I need it to complete my collection... Bob
