ORIGINAL QUESTION:
> I have an SS10 running SunOS 4.1.4 that is acting as a workgroup server.
>With all of the processes that are running, it is getting kind of loaded
>down (smb, atalkd, lpd, mail, NFS, etc.). It currently has 32MB RAM.
> I have a second SS10 with its original CPU card + 32MB RAM that is unused
>at this time.
>1) Can I take that CPU S-Bus card out of #2, and plug it into the #1 SS10,
>and get an increase in performance?
> (The RAM will go too, but I am not worried about that).
> The kernel on the 1st machine is a sun4m, SunOS 4.1.4
>2) If the above are "yes", can I just power down, plug it in, and power up
>- or - is it a major OS reinstallation?

The replies ranged from "Sure, no problem" to "No way, it can't be done".
Short answer: YES, You can...BUT only if they are newer.
In my case, it is something in between.
In general, the newer SS10 have system boards & CPUs that will support
multi-processors. Mine were too old. BUT...I have a Sun service contract,
and they replaced the system board and the processors for FREE (except for
the $5k/ year HW Support contract). My original CPU was a SM30 (I think)
with no cache. I included a script file that told me that it was a Model 30
with a 36MHz CPU. These were replaced with SM40.
Some of the replies said that adding RAM would improve things
tremendously. I bought some more RAM.
SunOS 4.1.4 (Solaris 1.1.2) seems to support dual processors just fine. I
include a "top" listing at the end.
While I was waiting for the service guy to show up, I called "Solar
Systems" in Preston WA. USA ( http://www.solarsys.com/ ), and ordered ten
16MB RAM modules ($75 each) and one Ross "Hyper-Sparc Dual 100" CPU module
($1,000). I ordered on Wed, they delivered on Thus. The Hyper-Sparc has two
Ross Hyper-Sparc chips and some cache on a single plug in card. The rep at
Solar Systems said that the Hyper-Sparc was compatible with Solaris 1.1.2
(SunOS 4.1.4). The Sun tech support guy was not completely convinced, but
we tried anyway. AND IT WORKS. The only "problem" is the CPU module takes
up two side-by-side slots in the chassis. There is room for two of these
CPU cards, for a total of 4 CPUs.
The upgrade was as easy as:
down the system
undo the screws holding the system board in
R&R the system board
redo the screws
power it up
We were done in 30min. I didn't have to change anything. There was
immediate improvement. With 128MB of RAM and dual CPUs, everything is MUCH
better. I will now think about changing to Sol2.5 o get better SMP
performance.
TOP output. Notice the "run/1" or "run/0", and the "spin". I belive these
are telling me it is doing some Multi-Processing.
