FreeNAS with Dual CPU (only one work?-why)

[Robert76]

Hi,

I have Intel dual CPU board and 2 Xenon CPUs...
I have noticed that after installing FreeNAS that power consumption dropped by half, it shows I have 64GB(what would suggest both CPUs are working as the configuration I have is that if motherboard does not see 1 of the CPUs, it will show only half of the available RAM)
Anyhow BIOS shows 2 CPUs are working, BMC Console as well, whole RAM is visible by FreenNAS but the power consumption dropped like only one of CPUs would work.
In FreeNAS I do not see in any place that I have 2 CPU-s.... should I?

What's up? is it normal?

On my systems, FreeNAS 11 has much better power management (and less consumption) in comparison to 9/10. What OS are you comparing to?

My backup Dell system has dual functioning CPU's.
FreeNAS "System" "Information" shows:
Build FreeNAS-11.0-U4 (54848d13b)
Platform Intel(R) Xeon(R) CPU E5630 @ 2.53GHz
Memory 32721MB

No.

It is probably because the system is idling down when there is no reason for CPU load.

No OS, just when I was switching on server and be only in BIOS, the power consumption was twice higher (around 189W) basically doing nothing, and now it consumes 123W during copying multimedia of 3TB from external network drive to FreeNAS share.... but when not copying or doing any other special action on FreeNAS it is showing between 90-100W....., so looks like FreeNAS will save my bill and use CPU power efficiently :) anyhow could show somewhere there are 2 CPUs and how busy they are.... ;-)

The BIOS doesn't do any power management.

No. It doesn't do that.

It does list the cores during boot that should be in the log file.

SSH in and try:

Code:

dmidecode -t processor

That should identify the processors in use.

You can also run top, and hit "P" while it runs to show all processor stats. My box shows 32 CPUs - dual E5-2670s (8 cores each) with hyperthreading - 8*2*2=32.

Or just open up a shell somewhere and use

Code:

dmesg | grep FreeBSD/SMP

Should get something like

Code:

FreeBSD/SMP: Multiprocessor System Detected: 16 CPUs
FreeBSD/SMP: 2 package(s) x 4 core(s) x 2 hardware threads
