You can still automate with a script hack but there has been concerns about the stability of the Infortrend controllers under high load so I would certainly investgate further with 100+ servers. Note that this is with the older series I haven't heard anything about the new powerPC based controllers. There was a recent thread on the cyrus list about using it under NFS with NetApp's but I do not remember the conclusions drawn from that. That might be a possibility for you. I don't believe there currently is a "recommended" SCSI<->SCSI RAID controller for FreeBSD. It used to be the Mylex 960SUI but I think David Greenmen had some issues with that. The CMD was another one that has fallen in/out of favor several times. At this point in the FreeBSD evolution, I would consider the Mylex/AMI PCI controllers if they're an option. Mike Smith works for FreeBSD and wrote the drivers so I feel a lot better about the stability and support. I believe they're both supported under 4.0 and 3.x-stable however you can not boot from a RAID volume under 3.x yet.
