Hi 2 week's ago I changed my server to more powerfull server with dual xeon e5-2670.

 

was working pretty fine but yesterday the parity check was activated(1 every month the first running on this server)

 

And surprise I get on 3 drives multiple read/write errors, the powersupply have 700W but I have a sai with 480W, could be the problem?

because doesn't have sense to have 3 drivers with errors.

I restarted the server and now i'm getting a drive disabled,

Maybe the sata cables, maybe the controller?

 

I have the MB http://www.asrockrack.com/general/productdetail.asp?Model=EP2C602

 

what should I do, i don't think have any problem with the HDD, checking the S.M.A.R.T data all is fine.

 

EDIT:

I checked the HDD, all are fine, i suspect something releated with the PSU because the  3 HDD are connected to the same PSU electric cable(the typical cable with 3 sata connectors)

 

For now I replaced the sata cables and conected this 3 HDD to different controller.(SAS controller)

 

 

 

Don't really understand what you are saying about the power supply

the powersupply have 700W but I have a sai with 480W

what does this mean?

 

Also since it doesn't match your sig tell us the exact model of your power supply. And update your sig.

Hi sorry it's 850W the psu

 

about

the powersupply have 700W but I have a sai with 480W

maybe i'm wrong but i thought your power supply is limited to the sai output, it isn't?

 

my sig is fine is exactly the machine were i having this trouble.

 

 

I though the problem was the power supply but I changed the sata cable of the 3 drive that I get disconnections and changed to an other sata controller, ran parity check and no errors and no disconnections.

 

It's weird to think about  this 3 cables have problems, and I have more HDD pluged to this "problematic sata controller" and are working fine.

 

So i'm not sure what is the problem

 

 

Don't rule out the SATA controller. I had a very similar issue where each drive would read/write fine, but when something i/o intensive happened on the controller involving multiple drives (such as a parity check), bad things would happen. I kept getting parity errors, disabled drives, etc. For me it was the pcie sata controller. I replaced it and haven't had an issue since.
