You cannot have more performance because Synology uses Raid...but its 70W/30W figures are quite good. For sure it is also less noisy.

 

Still, do not see the reason not to enable S3 for my chassis bought from Tom.

Anybody here uses MD-1510/LL?

 

I meant CPU performance. It's what matters if you run additional features like Php / MySql / Apache / media encoders / video transcoders, etc. Disk write is a non-issue with a cache-disk for unRAID, and even less so considering the server purpose is more for reading. My system is not completely passive, but it's close since it uses a low-wattage mobile Intel Core2Duo.

 

In any case, you can install S3 functionality yourself. That's the nice thing about unRAID, being able to modify everything.

Good, but there are no these things here. unRaid comes with zero features and I need to add all these alone.

Anyway, I have my Windows server for sporadic tasks.

cache-disk is unprotected. What's the point? You can loose your data.. It is like cheating yourself :-)

This is exactly what I asked.. What are recommended settings for my BIOS.

 

It is very simple..

When machine is idle, it shall reduce voltage for CPU, slow down fans, spindown disks..

 

after another timeout, it shall enter S3.. to be awaken later via power button or WoL packet

OK

I measured yesterday power consumption of the whole apartment using the Wattmeter of the electric company, it was 3.6KW during the period of 9:00 to 17:00

 

You can NOT get accurate power readings that way.  There are way too many variables.... for how many minutes was the how water heater running?  How many light bulbs were on/off differently?  TV on or off?  Refrigerator compressor?

I did same measurements day before with Lime server powered off.

So I measured the delta, what's wrong with this approach?

The sampling window is big enough - 8 hours..

 

I will have next week power meter, hopefully it will give me some more precise measurements.

If the sampling window is big enough, the other power usage would probably be consistent... But it depends on lots of factors... (Your home's energy usage during those two 8 hour windows could be vastly different weekday/weekend, or cold-day vs. warm-day)    If they were very similar, odds are your estimate is close.

I will have next week power meter, hopefully it will give me some more precise measurements.

I'll be curious as to the exact measurement too.

Dishwashers tend not to be run daily but can make a big difference.

 

You'll be amazed once you start just how much each device consumes and how much it costs. 

Tom,

 

in the meantime (until I wait for the power meter to arrive), how do I configure properly my box to enter S3?

I can awake my Windows machine either with WoL packet, clicking on power button, moving the mouse or pressing the keyboard.

I would like to do the same with Lime machine.

 

Could you please help?

Tom does not support this S3 feature and you are unlikely to get a response here.  You might be able to get one via email but it will probably not be very helpful.  There is a thread in the Custimization forum and you can probably find it liked in the Topical Index of the Wiki.  There are pretty good directions there and you are going to have to just mess with it andtry to get it working yourself.

It is highly dependent on your specific motherboard and how it can be put to sleep and woken up from the s3 state by Linux.

I have a system from Tom.

His motherboard.

 

I do not want to mess with BIOS.. and to change something that will effect other things..

Then, i am sorry to say, you are unlike to get S3 working.  I am not trying to sound like a pain in the ass, but S3 is spotty at best as it is.  Whether that be on on a system from Limetech, or a user built one.

 

The directions in the Wiki are pretty clear and "messing" with stuff in the BIOS is probably going to be needed.  There are packages that will need to be installed and tweaks that will need to be put in place becuase your board is different than others boards.

 

Changing some BIOS setting will have no effect on the data on the drives and will not do anything to hurt that.

If Tom supported S3 sleep then unRAID and your server specifically would have had S3 sleep included and enabled by default. These are considered user support forums. So, it is unlikely to the point of no chance that he will provide answers here for how to use S3 sleep.

 

It would be nice to see Tom at least get his servers set-up for sleep some day. Still, sleep requires more thought than just turning off - Do you wait until other devices are turned off? Use an external "sleep" command? Sleep after a certain time? Sleep at a certain time of day?

 

Then - How do you wake the server up? The server is more or less the equivalent of being turned off - it can not monitor for network traffic requests like it does for disk spin-up. So, this requires something like a magic packet to be sent from another machine which is more set-up and user understanding.

 

 

Going by the post made by dlmh

40 watts for MB

8   watts for disk controller cards

20  watts for idle disk drives

25  watts for fans  (I'm guessing 5 fans @ 5 watts each, one on CPU, one on back of case, 3 others behind disks)

 

Can I point out;

 

WD Green drives are about 0.66W idle x 5 = 3.3W, not 20W

 

Fans are about 2.5W full-voltage for a 120mm fan and the power drops with lower voltage - 5 x 120mm fans with voltage control should be <10W

 

You have to watch some of these "estimator" numbers because some are quite high.

 

I'd even question the disk controller cards - 8W is likely high considering the IC's that are on those cards without heatsinks.

There is a very basic sleep or power off mode that is possible.

Most modern bios's include a power up option, that allows the server to be automatically started every day at a certain time.

With a little bit of script work, a cron entry can be installed that will power off the server every day at a certain time.

 

While not S3 Sleep, it could save at least half a day's power every day using very minimal support.

 

It's a bios change.

And a cron install script called from the config/go script.

 

I have not set this up on unRAID, but I have set this up on other machines.  So it is feasible.
