"Can the raid controller recognize 4 TB drives?" No.  In RAID mode, 2TB drives are the maximum size supported.  In non-RAID mode (left unconfigured), it should recognized the entire capacity. "Can I use them in a RAID 5 for 12 TB of space?" No.  The SAS 6/iR does NOT support RAID 5 and does not support larger than 2TB drives. "Can I use them in a RAID 10 for 8 TB of space?" No.  The SAS 6/iR does NOT support RAID 10 and does not support larger than 2TB drives. You "might" be able to use 2TB of each drive in a 2TB RAID 1, but there is no guarantee that it will recognize all 2TB of usable disk space.  Larger than 2TB drives often are seen as much less than 2TB, sometimes as little as 760GB. You will need to use 2TB drives or upgrade your controller to an H200 or H700: H200 - supports >2TB drives, RAID 0/1/10, no cacheH700 - supports >2TB drives, RAID 0/1/5/6/10/50/60, 512MB or 1GB cache You should also not use consumer/desktop drives on any of these controllers.
I have an R310 with a SAS 6/IR controller. Can the raid controller recognize 4 TB drives? Can I use them in a RAID 5 for 12 TB of space? Can I use them in a RAID 10 for 8 TB of space?
