What RAID controllers are there that meet the following?
- Works out of the box with good performance with Ubuntu 10.04 LTS
- PCI-E 2.0 x4 or x8
- Support for 8 or more SATA/SAS 6Gb/s drives
- Enough internal bandwidth to support full speed of all drives simultaneously
- Able to expose all the drives as JBOD so that Linux software raid can be used
