Uni, their 11/780s were running a very modded and tweaked Unix and could
have a hundred or more students logged in on the one machine. Whether it
was crashy or not, they got more bang-for-buck out of their VAXen.
You certainly got more bang when your disk crashed. I ran a VAX cluster
with 15 years with shadowed DSSI drives and never had a disk corruption, I
replaced members of shadow sets when they died but again I never had any
issues of corruption and data loss. Meanwhile I also lived with an array
of Ultrix boxes and SunOS boxes where I had to clean up disk corruptions
or do restores from tape onto new disks - usually in the middle of the
night. Your work is always done faster if you skip steps.
