I work for HP, but in Enterprise Storage Arrays, i'll have to harass one of my server-savvy brethren about how the power supplies stack up...i think the second set of three are necessary if you upgrade the server to 8 CPUs... it's pretty basic. only 4 CPUs, 2 x 1GB DDR2 per CPU, and a pair of 146GB 2.5" drives...has nothing installed in any of the PCIe slots... so not a lot of extraneous wattage usage inside the sucker.

and i went down and looked at it, they're 1200W power supplies, first 3 aggregate, 2nd three are just for redundancy. so at 120V input voltage, the 1200W PSU's deliver about 900W each, for 2700W total available. no problem whatsoever on power. just a matter of what video cards it'll let me stick in there. :-)

Wow.  Not bad - I agree - it *should* be a case of what physically can fit.  Do the power supplies have the 6 and 8 pin pcie connectors?  each GPU (depending on type) will need at least 1 if not 2.  for example a 7970 uses a 6pin and an 8pin connector. 

And i would expect that a server case that size should have HV airfans (esp with 4 cpu's) so you might actually get livable temps with 4 or 5 stock 7xxx cards...


THis particular server appears to cost a significant chunk of change...  If you were paying full (or even refurb) prices, mining would not be cost effective i would think..  but i assume since you work there you might be getting, what, design test models?  I have picked up several of the those (in the intel brand) before for good prices (although not for mining).

yeah, it's a discontinued model from about 2-3 years ago, G5 (we just launched Gen8 servers), been written off and marked for disposal, so nobody's gonna care if i want to break my back haulign it home.

I'll have to look inside and see if there are extra PCIe power connectors, i wasn't looking for them earlier....that could hose me, and restrict me to lower end cards that don't need extra power leads....

And they would be REALLY low end.  not more than 20-30 MH/s with the cards that use the standard power connectors.

Not to worry on the connectors - if you dont have them (and you may not because it is a server) - they make converters like this one:
http://www.newegg.com/Product/Product.aspx?Item=N82E16812400034

Just be aware of how many modulo connectors you do have and how many you will need.   Also, if you can get specs on the power supplies you also want to see how the power connectors are connected internally - ie.  how many "rails" there are because internally in the power supply you want to balance the power draw across however many internal rails there are to prevent popping a fuse or blowing a cap or something like that.  That being said a 7U server with that kind of P/S upgrade capability should be able to be worked so it could support 4 cards.  I assume you can get additional or higher capacity PS'es through channels if need be?

Its seems like it should be simple to do this doesnt it - but nothing ever seems to be as simple in practice - I still think you may have a great starting point - but it will still take a bit of rigging to get it just right...

I sympathize with you on all that - i just finished building a new SQL Server for my datacenter and it wasn't as simple to arrange things the way i wanted as it could or should have been.

I don't suppose you want to send ME one of those to play with...  Wink

Hi all,

I'm Paul, and have heard about Bitcoin for quite awhile, but never really thought much about it. What finally pulled me in was reading an article about mining and realizing how similar it is in spirit to previous distributed computing efforts, like SETI@Home. I'm a dyed-in-the-wool geek and have loaded up distributed computing clients on entire farms of computing hardware in the past, just for something to play with.

My first thought was, "Wait a tick... I can do this!" I tend to be something of an obsessive researcher, and have spent the last month reading just about everything Bitcoin-related I could find. I bought a handful of coins, found a mining pool, started playing with different mining software, and made a couple of small purchases with BTC.

I think I've mined all of $0.50 so far, but I decided to take the plunge and gear up for the "ASIC revolution". It's a no-brainer for me... it's a new toy to play with, so even if I lose every penny, I'll still be glad I gave it a shot!

As I've gotten involved, I've found that I'm almost more fascinated by watching this small global economy grow and develop in real time. The unregulated marketplace is a colorful place: scammers, suckers, legitimate businesses, and everything in between, all trying to make their mark on this new economy. Isn't it interesting how, no matter which of those is your angle, it's in everyone's best interest to keep the BTC economy healthy and thriving?

Anyway, I digress. I'm just saying hello, and happy to be a part of the community. Looking forward to chatting with... well... most of you. Smiley

Cheers!

I heard about silkroad on reddit, started looking into it because it sounded interesting, and then I started reading into bitcoin. I'm interested in speculation and eager to see whether or not the bitcoin will be successful.

I'm UberNeck. Professionally, I do front-end web work specializing a few content management systems. I was first introduced to BTC through Tor and have since taken an interest in cryptocurrency. I comment under a different name on the reddit sub, but I'm jumping into this forum, as well.
