cell boards

Can anyone please let me know what are cell boards in hp servers. And what is the command to find the details of the processor means (its specification).

Re: cell boards

Hey;

I think you're combining two entirely separate concepts.

Cells are a hardware architecture that allows for electrical separation of hardware. Each cell will have their own cpus, memory, and (usually) I/O.

The CPUs in the cells would obviously follow the architecture of the entire system be it pa-ris or ia64.

HTH;

Re: cell boards

you can read a docs about cell boards

http://docs.hp.com/en/B9073-90183/ch02s09.html

you can view the processor specification

might help.

The Cell board is basically the motherboard of a standalone computer system. When processors, memory, I/O, power and cooling are all added and the board is within a chassis, you have a Cell -- which is really just a computing module which knows how to talk over an interconnect (external to the Cell bus) if needed to link with other Cells into a larger computing platform. Hence things like nPartitions where Cells are grouped (or left as singletons) to be used as different physical servers.

Re: cell boards

Hi,

Cells in HP mid-range servers allow multiple logical grouping of physical h/w (CPU, Memory, etc) using nPar technology. This configuration is initial setup at MSP.

Re: cell boards

One experience.

Power is not completely isolated.

The VRMs (Voltage Regulator Modules) are NOT isolated between cells. The is from experience with a failed VRMs taking down both cells in an rp7420 ( have experienced it 3 times in last 5 years).

Re: cell boards

Last Friday our main production server (rp7410) was down and was reported that one of the cell board has gone bad. They have replaced it. As it is a remote location i could'nt see anything. How can I know the specification of the cell board he replaced. Is there any way. The second thing is how to know the number of cell board there in the server.

Re: cell boards

parstatus -C is the quickest thing I can think of.

More detailed information per cell can be found with "parstatus -c N -V" where you replace N with 0, 1, ... [the numbers are from the first parstatus -C -- that tells you how many cells you have, in how many cabinets and what the numbering is... use that number with the -c (Cell) option to get more details]

Re: cell boards

Oh (and someone may know a way to tie all this together... I just relay what I do know), there's alternative information available via the MP console as well. If you go to the CM menu and do "PS" followed by C then 0 (or 1 or whatever number you want), you get information about the VRMs, Cell FSBs, which slots are populated, etc.
