Areca provides FreeBSD tools
LSI provides FreeBSD tools
Adaptec used to provide FreeBSD tools for most of their stuff, back when =
they were still around/relevant
Highpoint provides FreeBSD tools

Who am I missing... Emulex I guess, but they provide nothing for =
FreeBSD.  PMC maybe, but I'm waiting to see how their integration with =
the Adaptec assets goes before I pass judgement.  Marvell doesn't, but =
they don't sell into the channel anyways, only to integrators, and their =
chips tend to be used for crummy software storage stacks.  Qlogic, JNI, =
and other FC players, maybe?  The shortage of enterprise FC vendor =
support is disappointing, but I think that FreeBSD has a lot more =
deficiencies in that area than just vendor support.

In any case, there is definitely a lot more that "zero" vendor support =
for native FreeBSD tools.  It lacks in the low-end BIOS-based softraid, =
and it lacks in the high-end FC area, but the middle is covered quite =
well, IMHO.
