You didn't mention SATA 150 versus SATA 300 (aka "SATA 2") ? You didn't mention PCI width (32-bit versus 64-bit) ? You didn't mention PCI speed (33, 66, 100, 133 MHz) ? Attempting Hot-Swap with SATA drives is normally an invitation to disaster. The following are listed as supported on: http://www.openbsd.org/i386.html LSI MegaRAID SATA 150-4 (four disk) PCI 64-bit/66 MHz LSI MegaRAID SATA 150-6 (six disk) PCI 64-bit/66 MHz LSI MegaRAID SATA 300-4X (four disk) ? LSI MegaRAID SATA 300-4XLP (four disk) ? LSI MegaRAID SATA 300-8X (eight disk) PCI-X 64-bit, 133/100/66 MHz LSI MegaRAID SATA 300-8XLP (eight disk) ? You can get more info on the above from here: http://www.lsi.com/storage_home/products_home/internal_raid/megaraid_sata/index.html For some strange reason LSI is no longer listing the plain "300-4X" but it is still listing the "300-4XLP" If you have the wild idea of taking a four 500+GB drives and striping them together into a single partition of 2+TB size, realize the sane limit on OpenBSD 4.3 is only 1TB. I remember seeing Marco@ post something about building a 2TB partition, but he's a trained professional and licensed to do "crazy stuff" :-) -JCR
