We have a HP9000 N4000 server with 6xN-Class 440Mhz PA8500 CPUs. 3Gb RAM and HP SureStore E Disk System FC10. HPUX-11.
Can the curent CPU boards be taken out and upgraded to faster CPUs? PA-8700 for example? or do I have to purchase a new server. It would be nice to keep as much of the existing hardware as possible.
We need to install new software (including HPUX-11i) and the current configuration is under powered.
Thanks in advance.
Solved! Go to Solution.

You can uprgade to 550MHz cpus.

Re: HP9000 N4000 Server upgrading
It is no simple answer. The answer depends on your N4000 base product number. You can read the product number on right side of the chassis.
N4000 base product number A3639A supports 360MHz and 440MHz PA8500 CPU's. If it is yours case, you can upgrade the server by adding 2 additional 440MHz PA8500 CPU's.
N4000 base product number A3639B supports 360 and 440MHz PA8500 CPU's as well as 550MHz PA8600 CPU's. In this case you can just remove existing 440MHz CPU's and install 6x550MHz CPU's A5866A. If you want to install 8x550MHz CPU's you must buy one additional processor support module (one for two additional processors) A5168A.
The base N4000 products A3639A and A3639B have different system board.
You can also add memory. It depends on your current configuration. N4000 can have max 4 memory carrier boards (A4882A), each carrier board can have 4 memory modules:
- A3763A 512MB memory module (2x256MB DIMMs)
- A4923A 1GB memory module (2x512MB DIMMs)
- A5864A 2GB memory module (2x1GB DIMMs)
You can look at the link for availability of processors, memory modules and memory carrier board:

Re: HP9000 N4000 Server upgrading
If you want to upgrade to the PA-RISC 8700 CPUs, it would probably be cheaper if you just bought an RP7400 and moved your memory & disk over rather than upgrade your existing N4000 server.
Hope this helps

Re: HP9000 N4000 Server upgrading
when you say the system is underpowered,
first: are you really sure it is a CPU issue?
from your config my first guess would be to check memory pressure and disk IO.
second:
as the others said you could upgrade (with a system board swap) to 750MHz CPUs, however, before you do that you should consider the follow-up maintenance costs as well. Also the FC10 disks tend to be expensive regarding expansion and maintenance.
also, if your FC cards are A3704, note that they are not supported with HP-UX 11i.
Typically in such a scenario, if you consider investment and maintenance cost over two to three years, you will be better off with e.g. a new rp4440 with 3 dual core CPUs, 8GB RAM, and a SCSI RAID contoller with an MSA30. And it comes with 11i pre-installed

Bernhard

Re: HP9000 N4000 Server upgrading
Well, I fixed a badly running K box that had 3 large oracle DBs on a sym3430. By changing tuning parameters I reduced transaction time by 90%. That's right 90%. You can also look at the ndd properties. The performance improvement wasn't enough to keep the box that much longer, but the 7420 that the DB was later moved to has ***GREAT*** performance. I tuned it and things were so fast there was little measurable difference.
If performance is an issue tune first...
Run sar and graph your memory and CPU load. If you have issues after tuning, Some can be application related. Youmah have to shoot it and go to an rp74XX at 900 MZ. It can cost less than the maintenance with maintenance for the next three years on an older box.
