Will this s2ram be of any use to me? Or since my NIC is always getting set to wake on d, am I just SOL?
It is possible... particularly if s2ram has a specific knowledge of your mobo.
Run "s2ram -n" to see if it has your mobo in its database.
-
I have compiled s2ram (from the suspend-0.8 source).
Note, you will have to first install libx86 for it to run.
Both are in the attached zip file.
If you lose your video when you resume, or have trouble getting your machine to go into or wake up from s3 sleep, you may benefit from using s2ram instead of writing the state directly to /sys/power/state. s2ram is cleaner, and does some "preparation" of the system before entering s3 suspend.

Intel NICs are cheap and plentiful. Intel NICs built into mobos are not as common.
IPMI is not very common. Inexpensive KVM over IP boxes are easy to find.
The AOC-SAT2-MV8 works in a PCI slot, and does not have to have PCI-X.
OTOH. you can buy a 3rd party fan controller board with PWM control, and roll your own software to control it.
If you want a specialized feature, particular multiple ones, you are really limiting yourself by demanding it all come in one unified package. Pick one (IPMI, Intel Nic, PCI-X, Fan control) that you want integrated in the mobo, then use alternatives for the other ones.
-
I have found PWM fan control that I could manipulate with software on every mobo I've tried, on at least one fan port.
You can also check the speedfan website, and review sites like SPCR, which will often report where fan speed control was possible.
Unfortunately, your requirement of PCI-X slots, ECC memory, and IPMI greatly limits your choices. Why do you have such odd hardware demands?
-
My guess is that the mobo manufacturer either has not exposed the control interface on the chip to be software controlled, or there is something in the BIOS you need to change to enable it.
I'd e-mail tech support.
-
Did you try running pwmconfig?
-
No, install a full Slackware dev system on that box, build the drivers needed, and TEST whether you will have pwm fan control. No need to go on a scavenger hunt if what you are looking for won't work when you find it.
-
Did you run sensors-detect ?
-
The standard Slackware DVD is a live boot.
-
Which is the correct driver and how can I influence this? I am running stock unrAID 4.5.4 from an USB stick. Do I need to install full Slackware? Getting this to work is absolutely crucial.
If you are up to running unRAID on a full Slackware install, then that is your best option.
I would do a test install of Slackware first, and see if you get pwm control of the fans. If you do, then add unRAID. If not, you need to do more research on a driver for your chipset.
-
You may not be loading the correct driver. AFAIK, without pwm_enable, you will never have success.

I like Deltas for reliability.... I look for something in the 150 CFM range.
-
I would NOT use that fan in a server. It does not move enough air or produce enough head.
Get a 2800RPM or higher fan.... minimum. Then use pwm or a fan controller to run it slower (quieter) when you don't need the maximum airflow.
You size/spec your fans for the worst-case scenario... that means parity checks, with all drives hot and needing to be cooled.
You can always slow down a fast fan... but that Gelid fan, you can't turn up high if you need it.
-
You don't have any 3-pin headers?
-
Here is the difference between 4-pin pwm and 2/3-pin pwm.
In 2/3 pin pwm, the voltage is pulsed on pin 2. This has widely varying effects on different fans. some will stall with settings under 50. Some will double their RPM when changing pwm just a small amount, from 90 to 125. On another fam going from pwm of 90 to 150, may only increase speed a small amount. Some will have an annoying buzz.
In a 4-pin pwm, the 12-volts on pin 2 is constant, and a signal is sent over pin 4 to the fan, that tells the fan a percentage of capacity to us. If the signal says 25%, then the fan is supposed to run at 25% of max. If the signal says 60%, then the fan is supposed to spin at 60% of max.
Please look at figure 2 in this document:

Geez.... I can't make it any simpler:
You can only do PWM control to a 2-pin fan from a 2-pin or 3-pin fan header.
You can only do PWM control to a 3-pin fan from a 2-pin or 3-pin fan header.
You can only do PWM control to a 4-pin fan from a 4-pin fan header.
You can stick ANY fan on ANY header and it will spin (at full speed), because pins 1 and 2 are the same for all fans and all headers.
But you can only to pwm speed control in the combinations I explained above.
The BIOS can not give you anything that does not meet the above.... the BIOS may REMOVE some options or disable pwm, but only within the above limits
-
You can't use PWM to control fan speed when you plug a 3-pin fan into a 4-wire can header. The mobo will use the 4th pin for the PWM signal, and not pulse the voltage on pin 2.
You can only do PWM control to a 2-pin fan from a 2-pin or 3-pin fan header.
You can only do PWM control to a 3-pin fan from a 2-pin or 3-pin fan header.
You can only do PWM control to a 4-pin fan from a 4-pin fan header.
-
2-pin and 3-pin fans are both controlled with PWM
pin 1 is ground
pin 2 is v+
pin 3 is clock signal (speed sensor) (if present)
pin 4 is control. (if present)
http://www.formfactors.org/developer/specs/REV1_2_Public.pdf
With a 4-pin wire, a signal is sent on the 4th wire to the fan, and the FAN does the pwm. With 2-pin or 3-pin fans, the mobo does the pwm.
To lower the voltage from the standard 12-volt source requires something to waste (shunt to ground) the excess via a voltage regulator or a rheostat.
-
If the BIOS or some other setting is blocking PWM control, that may prevent pwm_enable from being available.
And on some mobos, it just won't work, due to lack of support circuits on the mobo. Cheap bastards!
-
Did you enable PWM control with pwm_enable???
-
I don't think life-support functions (power, cooling) should rely on an OS to function.
That's why you don't try to control CPU or PSU fans... they have their own self-contained control mechanisms.
-
I have been sleep/waking my secondary server for almost a year now, sometimes several times a day, and sometimes leaving it sleeping for weeks.... and it has worked flawlessly.
-
What is better, using the s3.sh script or the the s2ram?
You still use s2ram in a script..... s2ram is simply a better way of doing the command "echo 3 > /proc/acpi/sleep" (better tin that it can save the video buffer and do more housekeeping, etc.)
-
If your mobo supports PWM fan control, you can do it, but you need to write some scripts.
Or you can use a Matrix Orbital display module... the MX series displays have 3 speed-controllable fan headers and 4 ports for temperature probes.... but you'll have to write your own software to interface with it.
I am working on some unRAID specific software for the Matrix Orbital, but I'm having to do it all in C and my C skills are rusty

It defaults to "disabled" in the BIOS now.
I also have this board and like it. Only thing I don't like is the location of some of the headers make them hard to get to with cards installed.
