I am basically set on this as my first home server. I need to know once I stick 3 hard drives in there what the power draw will be roughly. I can't afford to jack up the price on hydro. Also will I need a RAID controller with this?

Also Home Server Builds welcome.


Server in question: http://www.ebay.ca/itm/HP-DL380-G6-2U-Server-1x-Intel-Xeon-QuadCore-E5520-2-26GHz-8GB-DDR3-P410i-/201507915345?hash=item2eeacec651:g:23kAAOSwqYBWmVJD
>>
>>52651004
I would guess around 150 watt in idle with 2/4 drives.
>>
Generally rack servers = high power consumption. Not really something you should be looking for if your aiming for low power consumption unless you gut the internals and stick low-power components in.

HDD drives are around ~5-10W each idle depending on the product. Check reviews.

if OP truely wanted just a home server, there are plenty low wattage options, like a NAS box or hp micro server.

the problem is that OP wants something loud and ugly to look at when he comes home from kindergarden
>>
>>52652537
HP microserver is enterprise grade hardware: iLO4, ECC memory, Xeon E3 CPU etc and extreme low power consumption.
Server shit does not magically consume a shit ton of watt compared to similar desktop components, old hardware does.
>>
>>52652791

This.

I am running a T20 with a similar configuration (Xeon E3, 12 GB ECC, 1x SSD, 2x 4 TB WD RED, Debian).

Idle power consumption is around 16 Watts.

>>52653744
If you're concerned about power consumption, you might want to swap those CPUs out for two L56 series Xeons.
You've got two 80w quads without HT right now. You can pick up a pair of L5630s for around $20. They're hyperthreaded, 40w each, and run at the same clock speed but support turbo boost.
>>
>>52651004
If you're concerned, the cpu alone will idle at above 50w. Also, you don't want to RAID power saving HDD's. If you really want to go with this chassis, pick up one of the lower watt cpu's on ebay. From personal experience, these servers are more or less obsolete at this point, and you're better off going onto an LGA1155 board so you can later upgrade to a v2 Xeon when they drop in price.
>>
>>52651004
get a mini itx with a onboard cpu, and if you really want a rack mountable case just buy one and build it from scratch, it'll save you headache from the sound & possible propertiery fan headers ( i had a HP before and those fans were 6 pin and regular fans didn't fit in )

They're 5 pin generally, and 3 pin fans work perfectly fine with them.

Fuck you!
I am looking for one of those as a home server since years, but here the price for used servers starts at like three times that of the US for the same model.
It is neigh impossible to directly get them from the previous owners as basically you will always have a company that is already standing there taking them before they are even shut down.

Add a decent rack mount case and power supply, now you're at $500 vs $175 and still have no RAM in the more expensive custom build.

>>52657522
enjoy your sound, servers ain't cheap if you want cheap onboard cpu's are better if its just filesharing + plex.
You will dump that server out of the window after 10 mins in your room.

I've had many 1-4u servers, in the end you'll spend the same amount of money on bills for your power then building a cheap onboard cpu server.
>>

If you are happy with a 11.5 Mbps max transfer rate (on a perfect signal), then by all means go for it. But I would never recommend doing that to anyone since it's ridiculously slow by modern NAS standards and you can't perform basic tasks like streaming (let alone encoding) 1080p reliably

ethernet won't be an upgrade since it's a 10/100 port. Will 802.11ac improve things? Marginally.

Since you already own it, sure it's functional. But a Banana Pi M1 is $35 and has gigabit ethernet and a sata bus, which means it will be quite literally 10x faster in real world scenarios

Where are you? I'm a server & storage technician in the UK, my companys hardware refreshes are fairly regular, I personally put six DL360 G6's in a skip (after having removed the drives, NICs and RAM of course) just before Xmas when we replaced them with G9's. They just can't be bothered with selling old kit, despite our suggestions otherwise. Not that this helps you though.
>>
>>52668511
>I personally put six DL360 G6's in a skip (after having removed the drives, NICs and RAM of course)

Fucking hell this genuinely upsets me a bit. Makes me want to start a business that buys used servers off companies that can't be bothered to deal with it and sell them on.
>>
>>52669206
Agreed. We're binning a fortune in perfectly usable kit, but management don't seem to want the effort of selling them. Admittedly some of the kit we replace is properly out of date and not even worth selling but most of our replaced hardware is worth good money, it's ridiculous.

So out in the skip they go, which is collected rarely so every day I come in and walk past them, soaked from rain and covered in leaves and rubbish. Such a waste. Taking one home with me however is out of the question as it's all tightly controlled. They may be worth money, but my job is worth more.

power consumption of server gear tends to not be that much different from consumer grade gear, part to part. however, there are some factors that tend to inherently drive up wattage/heat when examining spec'd out enterprise servers.

one of them is ECC RAM, you need more power/juice to do the error correcting and to power the buffer in RDIMMs, for example 4GB RDIMMs are about 3-4W a piece, pretty significant when you fill up entire banks in each server.

the next thing that tends to contribute are HBAs and raid controllers. these things tend to run hot by design and have high TDPs, not to mention additional juice for powering BBUs.

another significant factor is the PCH in the Westmere platform which is what a lot of people have been buying for a while now and what I continue to see mentioned in this thread...the dl380 G6 is an okay server but it uses the 5500/5520 PCH which is hot AF, the package itself tends to consume around 30w at idle. compare this to the sandy bridge C602 PCH for the E5-2600 product family, that only has a package consumption of around 7-8w. most processors in the same 'grade' e.g. xeon to xeon, not xeon to atom, tend to have similar idle wattages. so it's more or less the other things that really contribute to power consumption.

all that being said, buying nehalem and westmere-EP gear, aka stuff like, E5520, X5650, L5640, is all a waste of money right now. The E5-2660 and E5-2670 processors have seen significant price drops lately. the only problem is you have to wait around for a good deal on a 2P motherboard from supermicro and do a white box build as most barebones builds from HP and Dell haven't quite dropped in price yet.
>>
>>52670103
>nehalem and westmere-EP gear, aka stuff like, E5520, X5650, L5640, is all a waste of money right now
Disagree.

>The E5-2660 and E5-2670 processors have seen significant price drops lately
As have the Westmere-EP chips.
E5-2660 - 11891/$95 = 125.17 P/$
2x E5620 - 8304/$13 = 638.77 P/$
That makes the Westmere-EP solution a significantly better value.

Where in the UK? I'm near Nottingham.
>>
Anyone have a VPS?
>>
>>52671388
Price/performance ratio is a thing, performance/power consumption ratio is a whole different thing.
Westmere-EP is not only a lot more power hungry but also slower than a comparable Sandy Bitch Xeon E5 based platform.
A Sandy Bitch-E system will be cheaper in the not so long run.

Most companies can't be assed with selling off old hardware. That's why you contract with a reseller.

Your company makes a small amount of money instead of nothing.
Reseller makes a living.
End users get cheap powerful hardware.
Landfills don't get filled up with servers a few years old.

It's good for the environment, the economy, and every person or company involved.

You should seriously talk to someone higher up about this. There's no reason to be sending that hardware off to be crushed and thrown in a landfill. Even the bad hardware can be used for scrap recovery and recycled. This is of course handled by the reseller or the reseller's customers.

Be green.
>>
>>52672700
The first generation E5s that are so cheap really are not all that great. Better than Westmere-EP, yes. But not enough of a difference to warrant that much of a price difference given the low cost of power and how the typical 4chan user would be using the server. It's likely not going to be running at 50-90% 24/7, and it's likely going to be a single server.

If you're talking about a heavily utilized rack or two, then yes that difference is going to be much larger, but at that point you'd be better off with even newer hardware.

You can't throw out price/performance and just focus on power consumption/performance. The entire reason to even take power consumption into account is it's cost. For a single home server, a lower initial cost is generally the better investment. Spending a few hundred extra up front to save $5 a year on a single server just doesn't make sense for home use. The server will likely be retired before you ever see a return on the investment.

probably best to use consumer grade hardware mate.

also with the dollar down the shitter it might be tempting to buy used but I honestly wouldn't. servers are made to be ran in certain conditions and thus are noisy and power hungry as fuck.
