Thermopyle posted:I suppose...but then again the mobo is only $35. Yeah, after the first one he tried didn't work. There's no spot on NewEgg for "Provides power to PCIE devices without CPU or Memory" so a $35 board could end up being a $70 board.

Thermopyle posted:Well, don't buy the mobo from some place you can't return it to? I mean there is a reason this is a DIY project. I guess if you want assurances, buy an off the shelf product. Yeah, I understand that. It seems like the kind of problem some goony EE guy would look at solder a breadboard together that does it or something and sell it for some number of dollars.  .

According to specs, most hard drives pull 5A on the 12V rail at boot, which is the killer. Once they've spun up they take most of their power off the other rails, and they just sip it. Staggered spin up should be easier.

Obviously Erratic posted:So I want to build a Home Server box, but I'm limited by cash at the moment. mdadm (Linux) can do an in place expansion of a RAID5 set. Or if you don't care about your data you should be able to do some kind of RAID0 with pretty much anything and keep adding disks.

modeski posted:Of course. Not sure why I didn't think of that beforehand. Thanks! The only problem comes those drives first spin up. On poweron a drive will pull 2A from the 12V rail, so you'd be pulling 16A for a few seconds, which probably won't be a problem, but to be safe check the amperage on your 12V rails. One the drives are on they don't use nearly as much power, and they pull it from other less crowded rails, so it's essentially a non issue.

redeyes posted:This product was for home users though. Fact is that it kicks the rear end of any RAID5 I have tried. I mean point me to the RAID5 solution that has ~100MB/s reads and writes and also has fully automated incremental rotated backups for up to 10 computers on my network. Oh and my redundancy is based on each of my logical 'shares'. Makes it easy to optimize the use of your hard drive space. You can have a huge folder of throw away garbage and also have important data mirrored from the same set of drives. All automatic. You can also add or remove drives at will.. grow or shrink the storage pool. That's a strange comparison to make. You're comparing a form of disk redundancy to an entire operating system. AFAIK Vail will still do all of the backup stuff, it just won't have the DE stuff. Hell, with ZFS and Unix you could get most of the DE functionality (you'd just miss out on the automated backups).

SopWATh posted:I finally got the driver situation figured out, I had to change the SATA controller to IDE mode, and the IDE emulation had to be in "compatible" mode rather than "enhanced" Just so you're aware, you didn't actually figure anything out, you just disabled all the cool stuff that SATA gives you. What you've done is told Windows to address that drive as an IDE drive. It didn't work because Win XP has no AHCI drives, so it doesn't know how to talk to a SATA device by default. If you'd actually gotten the driver situation figured out, you'd have fun stuff like NCQ, but in the end it probably doesn't matter, just something to be aware of.

SopWATh posted:Yeah, I get that. I was originally hoping to slipstream the correct drivers into the WHS install disc, so that I could boot with in AHCI-mode out of the box. I think that requires a registry hack to get it to work. But to setup the drivers themselves, look for someething called dpinst. I'm not sure if it works or if it's what other people do, but it looks promising.
