During a blackout, a few of the UPSs won't work, which is fine -- they continue running with a slight loss of capacity.

We're all familiar with data centers where the centralized UPS turns out to not work during a blackout and everything goes dark.]]> http://www.dslreports.com/forum/remark,22258435 Sat, 18 Apr 2009 15:41:53 EDT Re: Googles Servers http://www.dslreports.com/forum/remark,22211120 Killa200 : they don't seem to have an orange 3.3v wire going to them.... which is no big deal as standard sata drives don't require it.]]> http://www.dslreports.com/forum/remark,22211120 Thu, 09 Apr 2009 16:20:59 EDT Re: Googles Servers http://www.dslreports.com/forum/remark,22210786 nnaarrnn : those are standard SATA drive with standard SATA 12v/5v/3.3v power plugs in them.]]> http://www.dslreports.com/forum/remark,22210786 Thu, 09 Apr 2009 15:16:17 EDT Re: Googles Servers http://www.dslreports.com/forum/remark,22200307 PunkGod :

The left most wires coming from the psu you see a Red,and yellow together, they go over the top of the mobo and plug into the drive.
The red and black wire goes directly to the battery. The yellow and black wires go directly to the motherboard. The tiny wires coming from the power supply go directly to the plug visibly laying on the motherboard.]]> http://www.dslreports.com/forum/remark,22200307 Tue, 07 Apr 2009 18:16:10 EDT Re: Googles Servers http://www.dslreports.com/forum/remark,22197654 kewlkeed : I give it a couple years and we'll soon now be seeing servers/comps with standard battery backups build directly into them like this. It would be nice as it's much more efficient than inverting 12V up to 110V only to be down converted to 12V and lower once again.

I use similar techniques on wireless sites and telecom sites I work on. Everything is standardized on either a 48V or 24V battery grid that can support the system for nearly a week without any additional power. Compared to that of perhaps an hour if it was done with traditional UPS systems.

The entire psu is solid 12v, so more than likely that board you see right under the sata drives takes in the 12v and converts is to a pass-through 12 and 5v for the drives.

As from the article "Power supplies convert conventional AC (alternating current--what you get from a wall socket) electricity into the DC (direct current--what you get from a battery) electricity, and typical power supplies provide computers with both 5-volt and 12-volt DC power. Google's designs supply only 12-volt power, with the necessary conversions taking place on the motherboard."]]> http://www.dslreports.com/forum/remark,22197374 Tue, 07 Apr 2009 09:35:36 EDT Re: Googles Servers http://www.dslreports.com/forum/remark,22197288 noobfragger : The left most wires coming from the psu you see a Red,and yellow together, they go over the top of the mobo and plug into the drive.

No idea on the hard drives. Probably a cable somewhere just can't see it.]]> http://www.dslreports.com/forum/remark,22197010 Tue, 07 Apr 2009 07:21:56 EDT Re: Googles Servers http://www.dslreports.com/forum/remark,22196844 PunkGod : Can anyone tell me where I could get a PSU that has the red and black wire coming out of it for the battery backup.

I don't understand how they're powering the hard drives. I don't see any wires coming from the PSU and going to the hard drives.]]> http://www.dslreports.com/forum/remark,22196844 Tue, 07 Apr 2009 04:58:30 EDT Re: Googles Servers http://www.dslreports.com/forum/remark,22190034 jazzman916 : Here is a video tour of one of Google's DCs:

Anyways just though you guys & gals ( :)) would find it interesting.]]> http://www.dslreports.com/forum/remark,22183326 Sat, 04 Apr 2009 14:34:34 EDT Re: Googles Servers http://www.dslreports.com/forum/remark,22182643 CanerisErik : I actually saw this in practice in one of the data centres a couple of years ago :)
