N4000 - Memory

[Leon Shen]

Hi,

Server N4000 is old name for HP9000.
I know memories are install on to Memory Module. May I know how many Memory Module can install N4000? how many slots per Memory Module? Is there any URL can find more information about N4000.

Best regards
Leon

If you have sysinfo, it will tell you:

I run from cron like this:

# Run the sysinfo3.01 script
0 6 1 * * /usr/local/sysinfo/sysinfo -a -b -o /usr/tmp/`hostname`.sysinfo >/tmp/sysinfo.cron 2>&1

Hi Leon,

N4000 has maximum 2 memory carriers each capable of holding 16 DIMMS. Remember that DIMMS are installed in pairs. If the system is up to date on firmware the max memory is 32GB achieved by 16 pairs of 2GB DIMM pairs.

Here's a link to the HW manual:

And to the upgrade manual:

HTH,
Jeff

Hi Malvin,

Thanks - I stand corrected.
I must have been thinking about L-class style RAM population....
Hey, at least I got the DIMM slot count right ;~))

Rgds,
