RAID fumble.
-
Often a DC is managed by a NOC. Technically the NOC and the DC are two different roles, but they so often overlap. When companies have both, it is common to have the NOC colocated inside of the datacenter.
Strictly, the DC folks (server techs, server admins, rackers, etc.) are the ones who touch the gear and the NOC are the ones you monitor and manage it - famously the ones with the big screens watching network performance when the boss is there and watching movies when he is not.

When you put them into RAID, the controller should be fully provisioning the drives at the drive level and then presenting you with only part of it. That you are only using part of the drive's capacity seems like it is part of it to you but to the drive, it has been fully provisioned.
Ahhh, I think I get what you mean. So given that it works that way, and given that our previous approach of pre-overprovisioning the drives didn't work ( http://mangolassi.it/topic/4614/how-should-i-determine-exact-over-provisioning-levels-for-1tb-samsung-850-pro-ssds-to-be-used-in-a-raid-10 ), is there just no way to do this?

I have a feeling that there is not. If you are going to do this, you need to control the RAID provisioning. But I am not sure if the RAID card is going to work with you on this or cause problems. That would depend very specifically on the drives and the controller and how they interact.
