Yep

OK so I went all out and got the SAS controller and extender and have a couple of questions I think I know the answer to but wanted to double check

1: The extender needs power only, do I have to use the molex plug or can I put it into one of the slots and let it get power that way or will it upset the way the controller and extender work? Dont really have another safe way to mount the card in my case

 

2: My system has always been a little....unstable, drives showing up as dead or dying every few weeks ect. Would the Marvell SATA multiplier been the a cause of the instability?

One or the other will work, you can use whichever is more convenient.

Could be, they are known to cause issues.

Thanks

This is usually a power/connection problem, could also be bad PSU.

Thanks again mate, I'll check it out

Ok so I'm back with more stupid questions. I'm getting a heap of CRC error counts on some of the drives, is it possible that the SAS expander card isn't getting enough power out of the PCi-e slot to power the drives properly? There is only 4 out of the 6 drives throwing errors and I thought it might be a cable problem to start but all of the problem drives are sharing a cable with one of the drives which seem ok. The errors only seem to happen when read/writes are happening but I'm guessing this is normal.

If this is possible can I just plug a molex connector into the card while its mounted in the PCi slot or do I need to remove it first?

Basic noob questions I know but just don't seem to be able to get a win

Thanks

Update the LSI firmware to latest to see if it helps.

Thanks, I'll give it a try at the weekend, brain doesn't fire on all 8 cylinders thru the week. I have taken the extender out of the mix and just running out of the controller it self and it seems to be running fine and dandy atm
