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

If you want JBOD, why do you search for the raid card? You may get much cheaper HBA i.e. LSI SAS3081E-R.

An HBA would be fine as well. Too bad that one you linked to does not do 6BG/s per port or PCI-E 2.0. – Dan Nuffer Aug 16 '10 at 15:35
I'm afraid there are no many SATA3 controllers in the market yet. A disk drives just don't require such speed, unless you have some expensive SSDs or DDR drives. 3Gbit per lane supports up to 375 megabytes/second - I even can't say what SSD model can fully support it. – disserman Aug 16 '10 at 16:25
