Hi. I've been doing research on hardware based raid with BSD and found something very confusing. I have a server with a 3Ware 7506-4 raid card. I'd like to migrate this server from Windows 2003 to OPenBSD if possible, FreeBSD if needed. Looking thru the supported hardware list for Raid cards the most I find is this:
"3ware Escalade 3W-5x00 and 3W-6x00 series (twe) (A) (C)"
This says the twe driver (http://www.openbsd.org/cgi-bin/man.cgi?query=twe&arch=i386&sektion=4) handles these cards. So I say ok lets go to FreeBSD. Upon checking FreeBSD's hardware compatability list I find the following entry:
The twe(4) driver supports the following ATA RAID controllers:
AMCC's 3ware 7500-4LP
Here is the FreeBSD man page for the twe driver:
http://www.freebsd.org/cgi/man.cgi?query=twe&sektion=4&manpath=FreeBSD+5.3-RELEASE

Are these infact the same drivers?

I'd say no. OpenBSD manpage says:

The twe driver was written by Michael Shalayeff <mickey@openbsd.org>, inspired by the FreeBSD driver by Mike Smith <msmith@freebsd.org>.

Ahh well. I guess freebsd it is then. Not much difference anyway, correct.

Tada! Just thought i'd post an info update. The 3Ware 7506-4 raid card is supported in OpenBSD 3.6 using the aforementioned twe driver!
