OK, my reasoning is this:
1. The z/Arch emulator hasn't got any ethenet support, just a CTC point to point link to the host
2. I'll run MULTINET on both the Debian S/390 and the host
3. I assume I need an area for that, or am I incorrect?

How was simh compiled? I used Visual C and the difference between running the compiler with optimization on or off made quite a difference for the generated code. And gcc might compile even faster codefiles.

Why is SIMH so slow though?
As far as I can understand, one MIPS is roughly one VUPS, correct?
So how come I get 14 VUPS on the same host running SIMH whilst my Hercules install peaks at 180?
Are the architectures that different (obviously they are) or what is it?

This seems like a natural for SIMH, since it already has a large
amount of necessary prerequisites (a lot of device emulation,
framework pieces, etc.).
There is Alpha support in the development track version of simh.
Is the architecture well enough defined in
publicly available documents? I would guess yes but I don't know for
sure. Are there secret bits that are critical and hard to obtain?
The architecture manual pretty fully documents it.

If the "fiddling" is similar to what is necessary to run VMS on the white box alphas then have a look at
http://home.zonnet.nl/hvlems
The white box alphas were tergeted at the WNT market. Adding two srm parameters works wonders for VMS. It does not involve hardware mods and AFAIK the mods are completely reversible.

Yes, the DS10L comes to mind. My HECnet node AXPEE:: is one of those.
They are EV6-based (nice and quick!) and are available clocked at
466MHz and 600MHz.
There are other 1U models, but that's the one I'm most familiar with.
If so could said system be considered to be a quiet one?
Eh, so-so.

Well, this is definitely a size/noise tradeoff, at least in many
cases. For low noise, you generally want large-diameter, low-speed
fans. For fans small enough to fit into a 1U enclosure, neither of
those are attainable, so you end up with the little screamers.

Hello!
Okay coming at via separate travel, actually private message.
Sounds good.

Eh, so-so.
For example I have here a SUN
UltraSPARC 5 machine who happens to be about that size and is
currently working headless, and serving as my website manager (hosting
entity and server for same.) it happens to be so quiet the only way
I'd know that the fellow is working is that I promptly logon to the
unit every few hours via SSH or bring up the site on the browser.
Certainly reasonable even if that's just about the worst machine Sun
ever built. ;) I'll bring some good (small) Sun hardware to the next
VCFe for you.
I'm trying to find a keyboard for the fellow so I can also use it as a
regular workstation, so far my regular source has not responded.
A Sun keyboard? I'm swimming in them. Send me your shipping address.
What I'd really like to do is to find another one, plus a keyboard,
and a terminal server that SUN made once. Having obtained them I would
simply configure Number Two as a webserver with its console out line
connected to that TS unit. Number One would become a regular
workstation.
I don't recall Sun ever having made a terminal server. But, I do have
probably a hundred Sun systems here, from 1U rackmount to 1800lb
machines with 64 CPUs.
I don't have many Alphas nowadays, and the one small one I do have
(the aforementioned DS10L) is in use, so I can't help you there, at
least not right now.
