SAS hdd question

LizardKing · 12 Sep 2010 at 15:35

Do the drives spin up as soon as they have power like traditional hard drives or do they wait to be initialised in the same way SCSI drives do?
The reason i ask is i have a sas drive connected to a dell sas6/ir card that is not spinning up and i cant tell if its the card or drive that's at fault.
thanks

I'm surprised no one can answer this

Maybe because no one here has used or has this type of storage setup?. Must admit, i have never heard of SAS hard drives until you mentioned them. From what i gather these drives are for servers and precision workstations, although having said that, gaming assets would see some speed performance boosts over a conventional 7200 sata. Have you tried contacting dell support?.

I've got a Dell R710 next to me and it starts the HDs shortly after the big Dell logo screen during the POST. By the it gets to the RAID card bit it already has them spinning. I remember some old SCSI based servers used to wait until the RAID card BIOS appeared first and then it'd start them in order half a second appart.

Darn - sounds like the hard drive is dead then. Do you know what RAID card the server is using?

Yup, it's a PERC 6/i. Sounds like you need some spare kit to test with.
