    [...]   I guess I am interested to know if anyone else is running
    stand-alone (serverless) systems, or can suggest just how much resource
    on our Sun/3 UNIX machines the necessary serving software will consume.
    My experience with Sun networks to date is that even the most
    pessimistic predictions of storage requirements have proved to be woeful
    under-estimates, so I am looking for practical experience as opposed
    to manufacturers' recommendations.   [...]

Storing a LOT of stuff on a Xerox server, we use about 80 Mbytes of
storage for several sysouts, lispusers, lisplibrary, on-line IRM,
fonts, and sources for one release of Xerox Lisp.  Each additional
release takes about 31 megabytes.  These are high estimates because we
have fonts for many types of printers, etc..  They do not include
user sysouts (the next biggest class of storage) or user files.

A Sun/3 is not a terribly good file server for d-machines because the
Xerox system tool doesn't speak TCP and the TCP FTP server doesn't
provide random access.

We've written an NFS client that runs under Lyric to provide random
access, but I wouldn't recommend it to anyone that is not expert both
in Xerox lisp and NFS details.  Eg., it doesn't recover gracefully from
hardreset.

If you're still using Koto, be sure to use the version of TCP.DCOM
filed in [sumex-aim.stanford.edu]<lispusers.koto>.  It's much faster
than the version released by Xerox ages ago.  (The mods were folded
into the version released with Lyric, FYI.)  I can send it electronically
if you don't have it already.
