Hi there, Can I ask why use a hardware controller instead of a MD device? MD devices are tons more capable and you wouldn't have problems with drivers. Also, from my experience, performance differences between hardware and software RAID are so small (unless you are in a CPU limited embedded environment) that are only noticeable in synthetic benchmarks and will never be noticeable in real life scenarios.

We use Areca controllers in some instances (the work is largely sequential access of large files). Out of curiosity, have the Areca drivers made it into the kernels released with RHE 5? I don't think they have a SCSI controller (excluding SAS). In this particular case, we are looking for a SCSI RAID controller to replace an existing controller and intend to continue to use the existing SCSI drives. We've had driver issues in RHE 5 with the Adaptec 2010S and were hoping to find a replacement card that would just work with the kernels/drivers provided with the release.
