LSI 9300-16i supported?

[Tobias Oberstein]

Hi Stephen,

thanks a lot for your info!

Btw: is Avago/LSI contributing all it's driver code for FreeBSD to be 
included in the FreeBSD source tree?

E.g. LSI has downloads for FreeBSD drivers:

http://www.lsi.com/products/host-bus-adapters/pages/lsi-sas-9201-16i.aspx#tab/tab4

Why is that? Is that different code than the one included in FreeBSD 
source tree?

I'd prefer to rely on standard FreeBSD source tree (definitely no vendor 
blobs .. but it seems the download above is source anyway).

I see.

I guess I go with the LSI SAS 9201-16i for the time being - probably 
"less risk". The fact that the 9300 has _two_ 3008 chips on one card 
could be a source of additional pain .. and then we have 3 of those cards.

My problem is: I'd love to use the newer card (more IOPS pushed etc), 
but this box needs to go to production real quickly, and costs some money.

There are enough potential sources of surprise already, like the box 
will have 8 Intel P3700 PCIe 2TB SSDs. We'll find out what 
FreeBSD/ZFS/PostgreSQL makes out of these;)

Cheers,
/Tobias
