Mt. Xinu vs. ULTRIX

Mt. Xinu vs. ULTRIX

Post by Dave Marquar » Tue, 02 Jan 1990 01:32:00

We are trying to decide whether to purchase Mt. Xinu 4.3 BSD+NFS or DEC's
ULTRIX, so I am looking for comments about these products, good or bad.
Also, if you've used both products, I'd be very interested in comparisons.
We are especially interested in knowing what kind of support we can expect
from Mt. Xinu or DEC.  Please respond by mail.  Thanks in advance.

We did a study before making our decision, and checked many references.
Most sites with Mt. Xinu seemed to be satisfied customers, while many sites
with Ultrix wished they had More/BSD.

Our experience with Mt. Xinu has been mostly good.  Just prior to the
release of 4.3, support for 4.2 kind of slowed down, but was still there.

We had a major problem that was the result of a coding error in NFS
that was SUN's fault, and appears in just about every vendor's release
of NFS.  This would result in corruption of data on the NFS client side.

Mt. Xinu shipped us a fix by uucp the same day they fixed it on their
own systems.

If we had been dealing with DEC we might have had to wait several
months before the fix had been properly packaged in the next update,
and had migrated its way to the shipping docks.

I'd say the choice is easy.  Go with Mt. Xinu.


1. Mt. Xinu vs Ultrix

        Can anyone out there let me in on the relative merits of Mt. Xinu
4.3 unix with NFS versus Ultrix?

        We are currently running Ultrix 1.2 (and waiting for 2.0). I am
interested in finding out the differences between the two (other than the
fact that Ultrix is a 4.2 clone versus Mt. Xinu's 4.3), and whether Mt. Xinu
offers support (or if anyone other than DEC does) for:

        - DECserver 200's (DEC's ethernet terminal servers)
        - DECnet  (we need to communicate with the VMS world also... argh!)

        The machines are Microvax II's (8 or 10 of them... I lose count! :-),
some running Ultrix, some VMS.

        One problem with Ultrix is that we currently don't have source, and
it is horrendously expensive (around $22,000 CDN - on top of the AT&T licence).
I would imagine that Mt. Xinu is cheaper. It would be *really* nice to have
source, but 22 grand is a bit much.

        If anyone has any comments/opinions about either Mt. Xinu or Ultrix,
drop me a line via email. I will summarize the responses I get to the net,
in case anyone else is interested.

        Thanks all,
