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) ?

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

Joachim Schipper wrote: I understand LSI comes highly recommended by people who should know. Intel SRCS16 and LSI MegaRAID SATA controllers both attached by ami(4) driver. LSI is known to produce above the average equipment so they can be desired. OTOH, Intel is not just another company. Love them or hate them but they surely know how to do good things (but not necessarily always produce them) LSI discloses hardware details to programmers AFAIK but Intel is simply not cooperative on this subject. Once upon a time they used to love BLOB for their popular wireless networking products. marco@ ported mfi(4) from FreeBSD. Which is LSI's SAS controller. I don't know if he had access to any developer's manual but his blog entry on undeadly tells us he liked the clean hardware design which offloads the dirty work to the firmware. http://undeadly.org/cgi?action=articlesid=20060519224204 If LSI is cheaper, buy it. If LSI is unsignificantly more expensive, buy it again. If Intel is way cheaper, buy it then. That's my 2 cents.
