MODEL DIFFERENCE

Can someone tell me what the difference in the two models are?

# model
9000/800/N4000-44
and
# model
9000/800/N4000-55

the 44 and 55. Is one an rp model and the other an n4000 model. The systems physically look the same.

Re: MODEL DIFFERENCE

Hi,

I think it identifies the cpu speed.

n4000-44 --> 440MHz CPU
n4000-55 --> 550MHz CPU

Hope this helps.

Re: MODEL DIFFERENCE

Yep..

Definitely speed. My N-Classes are:

9000/800/N4000-65

They're 650Mhz PA8700 CPUs.

BTW - anyone, is there a difference between the N-Class and thr rp7400? Or do they refer to the N4000's?

Re: MODEL DIFFERENCE

From my understanding, the rp systems are big brothers to the N class systems.

Re: MODEL DIFFERENCE

Hi,

rp is the new naming convention for risc servers, rp7400 is n4000 (big brother ? --> u can say that).

check out this powerpoint slide for the hp server naming convention.

Hope this helps.

Re: MODEL DIFFERENCE

Hi,

As mentioned, the suffix is supposed to indicate the processor speed of the CPU. But I wouldn't put my complete faith in the model number suffix. We had an L-class box once where the model suffix didn't match up to the CPU processor speed. Our local HP CE took an interest in the problem, and it took him a couple of tries and several hours to get the model suffix corrected.

In other words, I would double check a system that is supposed to be 550 Mhz when it has a model number like N4000-55. It should match up, but you never know. :)

Re: MODEL DIFFERENCE

Hi Robert,

rp7400 is the new name for N4000 (new naming convention).

9000/800/N4000-44 = N4000 with 440MHz CPUs
9000/800/N4000-55 = N4000 with 550MHz CPUs

Both systems can have different system board also.

First release of N4000 has system board A3639A and works with 360MHz and 440MHz CPUs

Second release of N4000 has system board A3639B and works with 360MHz, 440MHz and 550MHz CPUs.

Third release of N4000 has system board A3639C and works with 550MHz, 650MHz and 750MHz CPUs.

So your 9000/800/N4000-44 has A3639A or A3639B system board, and 9000/800/N4000-55
has A3639B or A3639C system board.

Re: MODEL DIFFERENCE

Zymunt is very close. The A3639A/B/C are the actual part numbers for ordering purposes. The system board part number is different yet. Each model did have a different system board, to the handle different clock speeds ranges.

Re: MODEL DIFFERENCE

Hi Robert

You are right the machine was first Called an N-Class at this point in the middle of the product growth HP introduced a renaming strategy and it was renamed to a RP7400 even though the moddle strings reflects the old naming convention.

The core differnece between the two is the processor speed 440Mhz vs 550Mhz. There is other differences in terms of io paths for the onboard stuff, especially consoel and gsp ports, and ups port.

But out of an end user perspective the biggest one is the CPU speed.
