Last night I finally got around to installing another Raid5 array for media storage. I used a 3Ware 8000 series SATA PCI card that supports 8 drives bought on eBay. I purchased Larry Rowland's two A-Tech Mass Media cases: http://www.atechfabrication.com/products/mass_storage.htm with 4 Western 250 gig SATA drives in each.
Knowing another 8 drives on my server that already has 8 drives needed a lot of power, I purchased a new Antec Phantom 500 watt powersupply. I bought this one as it's fan only turns on when needed so it is silent otherwise. This server is in my Theater equipment closet, so it needs to be quiet.
Also purchased some 1 meter SATA cables as the ones that came with the A-Tech cases were too short for my installation. Found those at a great deal at: www.satacable.com for $1.70 each including right and left hand ends.
Put it all together and ... no boot. Not enough power (sigh...)
Did the math and it should have worked (watt draw times drives plus the other 2.8ghz / 1Gig Ram PC stuff draw). Did some additional research and found this new fangled power supply divides up the 12 volt supply into two seperate supplys. Only half the wattage is available to the drives! The other half feeds the motherboard (17 amps for the motherboard???).
Pulled the $200 funky power supply and put the original back in (Enermax 460 watt: http://www.enermax.com.tw/products_page.ph...Gid=26&Gid2=38). This one has 33amps going to motherboard AND drives. Everything booted fine. Packed the Phantom up for a MicroPC return on Monday.
So, onto configuring the drives. I reflashed the 3Ware firmware and bios to latest and all drives were found on next boot. I selected 7 drives for the Raid5 array and left the last drive as a Hot Spare (in case one of the other drives fails, the HotSpare replaces it without any supervision). 1.5 terabyes of backed up storage.
Enabled, Single Partition, Format NTFS, Shared the drive, and the Media Servers are ready to go.
The A-Tech cases quiet the drives to almost undetectable. The Server, being H20 cooled is almost silent too. The Enermax power supply has a little whir, with the entire server quieter than my Tivo Series 1 units (as comparison).
Just have to go to HomeDepot tonight for some brackets to build a shelf for the A-Techs and the Zalman Reservator water cooler (http://www.zalmanusa.com/usa/product/view.asp?idx=160&code=021). I am also looking to wrap the SATA cables in some nice woven tubing with heat shrink ends to clean them up.
