Here at work, we=B4re successfully using a Highpoint 1820A S-ATA RAID=20 controller on a HP ML110 server, this card is (at least apparently)=20 fully supported by FreeBSD by Highpoint itself, and works fine. There=20 even seems to be some drivers enhancements in version 5.4-RELEASE. One thing to note is that this 1820A supports up to 8 disks in RAID=20 modes 0,1,5, and JBOD, and (important) it=B4s 100MHz PCI-X, but there are= =20 simpler, standard-PCI versions for up to 4 disks. As for performance, we=20 haven=B4t done yet any serious testing, but rough calculations from commo= n=20 file transfers indicate something between 60MB/s and 80 MB/s on RAID 5. As for Promise controllers, we=B4re not being much happy with the S150=20 SX4, and we=B4ve got some trouble with integrated Promise chips, but thes= e=20 were last tested on FreeBSD 5.2.1. I don=B4t remember the exact chip=20 models, but they were from Asus P4P800 and P4C800. I didn=B4t test=B4em=20 after that, but there seems to have been various enhancements for pst=20 driver on FreeBSD 5.3. It=B4s not quite the platform you desire (Intel P4), but I hope this ca= n=20 add something. ;) Cheers, Tulio > Both 3ware boards are on similar based hardware: Tyan S5120AGNF (tomcat > i915g), PIV 3 ghz-HT disabled, 2GB of RAM.
