March 29, 201115 yr Hey all, As I am in the process of specifying new hardware for a 24 drive system and with purchasing my first Kill-a-watt meter, I was hoping that we could all post some figures to get an idea what current hardware/hard drives are producing in terms of power consumption. I want to build the lowest power 24 drive system I can... Yes, 24 drive and low power sounds like an oxymoron, but I don't want my windmill and solar panels to 'blow a fuse' I figured we ought to create an outline like all good threads on this forum use: [b]OS at time of building:[/b] [b]CPU:[/b] [b]Motherboard:[/b] [b]RAM:[/b] [b]Case:[/b] [b]Drive Cage(s):[/b] [b]Power Supply:[/b] [b]SATA Expansion Card(s):[/b] [b]Fans:[/b] [b]Total # of Drives:[/b] [b]Total # of ‘Green’ Drives :[/b] [b]Total Drive Capacity:[/b] [b]Boot (peak):[/b] [b]Idle – drive spun down(avg):[/b] [b]Parity Check(avg):[/b] [b]Light use (avg):[/b]

It seems very exciting to me so can you provide some information? Waiting for reply thanks in advance:) Would it even matter? The hardware would be three years out of date. You're better off just creating a new thread and asking for advice on low power hardware.
February 12, 201412 yr Agree any feedback from 3 years ago is not likely to be useful. You might get some useful info from this thread, which is less than a year old: http://lime-technology.com/forum/index.php?topic=27460.0 While you couldn't build a 24 drive system (unless you used a port multiplier), you could build a 20 drive system with this very nice little board and an 8-port PCIe x8 controller card: http://www.newegg.com/Product/Product.aspx?Item=N82E16813157475 From the reviews I've read, the board draws less than 30w when idle (no drives spinning). You'd have to add the idle draw of the PCIe x8 SATA card you added, but I'd still expect a 20 drive system to idle under 60w with this combination. A port multiplier would let you expand to 24 drives with a small additional wattage draw. Of course 24 drives all spun up will add ~ 100w, assuming you're using low-power drives. They'll also draw ~ 10 watts when all are spun down. [These numbers are based on WD Reds] So ... it's reasonable to assume you could build a 24 drive system that drew in the neighborhood of 60 watts when idle (drives spun down); probably 70w in typical use (1 or 2 drives spun up); and about 160 watts during parity checks, rebuilds, or while booting -- when all drives were spun up. I doubt you can do any better than that.
February 12, 201412 yr Note: You could actually build a 24 drive system without a port multiplier if you used a 12 drive controller ... something like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16816115059
