Hi,

I have a E450 which came with Solaris 2.6 and is running now Solaris
10. But the OS runs to slow for a so big system (4x400Sparc + 4G). So I
want to try Linux on it but it seems not to be easily to set up a Linux
(aurora) on such system. The system crashes already during boot by a
ram-disk exception. And a really old Red Hat edition boots but is not
able to handle the fan subsystem and all these ventilators continue are
running at full speed. That's not good because a whirlwind is coming
up in front of the system which takes all the papers and carpet tiles
up to the room cover.

So is there a way to use Linux on the E450 ?

Why do you expect Linux to be magically faster on such old (and therefor
slow) hardware? Expect a single CPU current PC to outperform it.

If you want to make it run faster, I would first try Solaris 10 or
Solaris Express; it has full support for all the odds and ends and
should run faster than Solaris 2.6.

(It will also run in 64 bit rather than in 32 bit mode)

What do you mean by too slow? Is Solaris 10 slower than Solaris 2.6?
How did you configure Solaris 10 (did you use ZFS, UFS, SVC on Solaris
10 which might explain the difference in speed if there is one).

What to you expect of 400MHz processors? What would you like to run on
the E450?

This might still be a valuable machine for applications that do not
require a lot of processing power, but benefit from parallelism such as
a database server.


The E450 is a noisy machine that uses a lot of current. I for one would
not want to have one at home, so it might well be that not too much
work has been done trying to get Linux to run on this hardware.


I don't know.

I would in any case be amazed if Linux would turn out to be
significantly faster than Solaris 10.

You know, it is almost always the case in the real world that something
is "fair" when you like it and "unfair" when you don't.

Slow? Well, what do you expect for such an old system?


You've gotta be kinding me. Why on Earth would you want to bother with
Linux on this machine?


Servers like the E450 were designed to be put into a server room, where
noise and wind are less important.


Perhaps, but I really doubt it would be worth the effort. Frankly,
I think it would be a waste of your time.

I tried to run an Apache 2 with MySQL and PHP and it takes over 25 sec
to fetch a simple PHP page which takes its menu from a database.

I used the ibib and also the sunfreeware suite to get this application
because the two servers which came with sol10 are not supporting PHP.
And that is the main problem after the slowness. I'm able to handle
Linux much better than Solaris.

I can configure, compile and install all the wanted packages and so I
will get an optimal system which could be completely customize and
maintained by me. On Solaris I have to take the precompiled packages
and so I have the same software on several directories
/usr/sfw , /opt/sfw, /usr/local and so on. After a short time I lost
the overview and had to reinstall my system from the begin on new.

And about the inet/init replacement on sol10 I will get a crises.

If it would work more powerfully then it may make Sinn to learn al this
Solaris specials, but so I will not spend my time on a system which
takes a lot of electrically energy to produce only wind, warmth and
noises.

Well, then there is something wrong with the setup. The E450 isn't a
very fast machine (by today's standards, but I can remember when it was
a _very_ impressive box), but it should not be that sluggish.

I'm quite sure that a bit of poking around would show why you see this
odd behaviour. I've a far less powerful system (an Ultra 30 with a
single 300MHz processor and 384MB RAM running RT (Perl with a MySQL
database) and a couple of PHP sites with sub-second response times).
And that's with Solaris 8, which is slower than Solaris 10.


That of course is a valid argument. But then one would question the
rationale for using an old SPARC machine if one isn't comfortable with
the OS.


There's nothing stopping you from downloading the sources, installing
Studio 11, and compiling Apache, PHP, and MySQL (or any other
database). No need to faff around with precompiled packages.


Why not simply remove the Sunfreeware packages? A couple of pkgrm's and
your as good as new.


It's actually not bad at all once you get the hang of it. But you have
to spend some time learning.


Look, it's an old datacentre machine. It'll never be as powerful as a
recent box, it'll never be as silent as an office desktop, and it
pushes a kilowatt when loaded. It might be cheap to buy, but it's not
something to put in your living room unless you need a coffee table. If
you want to play with Sun kit, get one of the plentiful Blade 1000
workstations that are going for cheap on eBay - they're very nice
systems that will handle Apache 2, PHP and MySQL with consummate ease.

If it's for professional applications, don't waste money on a system
that will cost more in maintenance than the purchase price a couple of
recent systems such as a T2000 - a perfect low-energy vehicle for web
page serving (and Sun will let you use one for 60 days to see if it
meets your needs).

Take care,

Well, as the others already told you this system is slow, and its old.
You should not expect up to date performance from a 400MHz UltraSPARC II...


Linux won't solve your problem. Either your task requires a more
powerful hardware, or there is something messed up with your software
installation.

Yes I agree totally. I used such system at SIEMENS Berlin at the end of
the 19. and it was a powerful system which was serving a lot of
XWin-Sessions an a ClearCase Server for many developers. That was the
reason I bought on of this at eBay last year.

Now I think it would be the best to install a seat and a driver
steering wheel on the top and let it be a nice bobby-car for the
children of my neighbour. Nice wheels are already installd

No problem. If somebody has a lot of knowledge on these kinds of
systems and would be so kindly to take the time to look on it then I
could open a ssh port to that system for them. Send a mail, I will do
it immediately. 0(°^°)0


It is very important for my to know what is going on on my system. If
there are installed the same library and tools on several places maybe
in different versions and bit-wide then my knowledge is not enough to
guaranties that the system is stable and almost protected on the
internet.

Yes I tried the Studio11 but I was not able to use it athok

Yes you are right. May be this system is not the right system for my
concern.
I need a system which is able to serve (hopefully more than) 30-50
http/https sessions using excessive sql-database access over PHP pages.

Thanks for your kindly and knowledgeable answer.
