unraid reduse energy consumption

[Drakenstrijder]

hallo. 

i want to reduse my power use.

dit is the hardware i want to use :https://outervision.com/b/FzO4Az

 

is there an way or are there tips for my to reduse energy cost.

is there for instance an way to time whene unraid is active. 

 

thank's in advance

What you should do is buy a Kill A Watt.

And plug your computer into it.  

 

IT will show you in real time how much power your box is using.  You'll find that during idle, the computer doesn't use all that much power.  That 440W is at absolute peak, not "at all times"

 

Once you see /actual/ power usage numbers you can make a decision on it.

thanks for the info but the link dusn't work for my

The recommended PSU wattage is based on the expected maximum power draw of the whole system. When the system is idle it should use a lot less than this. A 500W power supply can provide up to 500W, it does not use 500W when the PC is idle.

Something like this:

Also remember you need to quote @tkitch, otherwise they get no notification of your reply.

@Eigenvektor thanks, i'm an bit nieuwe in social media

Depending on the motherboard, you could look at undervolting the CPU. But Sandy Bridge Xeons, relative to Sandy Bridge desktop CPUs, are generally higher draw when idle.  Just a lot more silicon there.  You can also have it spin down drives when not in use and UnRAID will only spin up specific drives when data is requested.  This can result in a delay when UnRAID needs to spin up drives but it can save power and heat by keeping most drives idle.

@CerealExperimentsLain tanks for the info. the motherboard i want to use is https://www.supermicro.com/products/motherboard/Xeon/C600/X9SRi-3F.cfm 

i will look into spin down drives

You'll have to look into your specific board.  My UnRAID servers are both using Asus consumer X79 boards, so they have typical clock/voltage controls as you'd expect.  SuperMicro server stuff, never used it seriously, especially not for enthusiast sorta tweaking.

Make sure in your UnRAID you have your drives to spin down when theyre idle. 

Also configure your User Shares as 'high water' or 'fill-up' for the allocation method, so they utilize 1 disk at a time, rather than striping across drives. This will reduce how many drives spin up when you want to access files.

the best way to reduce power consumption would be to use different components.

 

This CPU barely is 20% faster then an i3 10100 but consumes 50% more power under load and probably 100 - 150% more at idle.

Spinning down hard drives also makes a difference but not that much if you are already consuming a lot of power.

 

My entire NAS with an i3 10100 10G LAN and an Intel SAS controller with 5 HDD´s connected as well as 4 SSD`s idles at around 50W and goes to slightly over 100W when all HDD´s are working and the HDD is doing some work too.

Valid points are made here. Your solution has a few drawbacks as well, so it all depends on what OP is really using the system for.

 

The Xeon 2650v2 will scale better with its 8 cores and 16 threads. This is great for virtual machines as you can

allocate a lot of resources without overcommitting. The RAM is also very cheap, cheaper than DDR4, and you get

the benefit of registered ECC support. If the board can be had for cheap, it's going to take a good while before the

power savings outweigh the upfront cost of going new.

@NelizMastri want to use unraid as normal nas for my parents, but also just want to figure out for myself what i can do with unraid. mainly playing old retro games or just tinkering with them to se what it al can.

The reazen that i use that cpu is becouse I helped my father's company move and got paid in old servers that they would otherwise have to throw away.

so I want to use this otherwise there is just nothing to do in my room

You can also get 12 core CPUs like the E5 2697v2 for around USD$140, great drop in upgrade.  Xeon systems have PCIE lanes up the wazoo, great if adding even more expansion options, say you wanted to add another SAS controller and connect it to a disk shelf?

 

Oh and rebuilding the whole server, that cost would stomp what you save on your power bill for a long time before you broke even.  When talking about 'saving energy' we should also factor in how much energy it cost to build the replacement as well.

that cpu is 130watt, that's way too much Watt in use, but thanks for the tip.

i'm not that good in english, what do you mean with " that cost would stomp what you save on your power bill for a long time before you broke even"

To make sure you understand, that's 130 watts only when it's going under 100% load.  At idle, just about every Socket 2011 CPU has the same draw.  So dropping in a faster, higher wattage CPU won't really increase your power draw unless you also increased your CPU load with dockers and VMs and like.  ...Of course, if you didn't have the need for more CPU power, it'd also make no sense to upgrade the CPU.
