Dell SAS6/iR Integrated SAS Controller Card Storage controller (RAID)- Serial ATA-300 / SAS- 300 MBps - Plug-in card, PCI Express x8, 2 CH, PC, Unix .
This RAID controller card from Dell only supports RAID 0 and RAID 1. It support 2 hot swap drives and has a combined 12Gbps throughput from 4 channels at 3Gbps. It's not a bad controller card for entry level servers and workstations but one of it's limitations is that it does not support RAID 5 or RAID 10 (RAID 0 + 1). I discovered this unfortunately when trying to configured RAID 10 (RAID 0 +1) in a PowerEdge r610 server.
