[comp.unix.ultrix] presto

Does anyone have any ideas on how to set up Prestoserve?

There was no information sent in my Ultrix 4.1 upgrade, and
the man pages for 'presto' refer to a document %%DNPresto%% which is
presumably not yet released.

I'm assuming that you have the appropriate hardware:  a DECsystem 5500
or the 5100 and its optional PrestoServe board.  If you don't have either
of these systems, then you can't use PrestoServe, since it consists of
*both* software and non-volatile memory hardware.

First create the device special file, if it does not already exist:

	cd /dev
	MAKEDEV pr0

Second, enable PrestoServe on the filesystems you wish to accellerate:

	/usr/etc/presto -u /dev/ra1c

Or just type plain old

	/usr/etc/presto -u

if you want everything served.

All the information you need is in the manual pages.  Just read
presto(8), dxpresto(8), presto(4), and prestoctl_svc(8).  I had
no documentation when I first saw a prototype 5500, and I managed
to turn on this subsystem for a benchmark.  (It made a pronounced
difference, BTW ;-)  If *I* can figure it out, then ... :-)

The only decisions you might want to make are basically whether
or not you are getting full benefit of the capabilities of this system.
You can use presto or dxpresto to view statistics which can give
you a handle on this.

Hope this helps,

    Are all of us who squandered our companies' capital budgets on 
    DEC {23}100s, DEC 5400s, DEC 58n0s, and DEC 5000s going to be left
    out in the cold on this product ?

You can upgrade a 5400 to a 5500 today.

If you think some other platform would make a good Prestoserve
host (the DS5000 comes to my mind), then I suggest you convey
your interest to your local sales office.

   .... that's very much appreciated.  Whether that is the sign of an "en-
   lightened"  DEC or a smart legal department, though, will only become 
   known if this novel practice is extended to other DEC RISC platforms.

  .... but the sales office mutters about higher-level "marketing decisions"
  and product "positioning".

  Hey, I like ping ppong as much as the bext person.  But it's no fun being
  the ball.
