Offtopic: Which SAS / SATA HBA do you recommend?
Hi all,
Sorry for the offtopic question. I hope though that others on this list or reading the archive find the answers useful too.
It seems the Adaptec 1405 4port SAS HBA I bought only works with RHEL and SuSE through a closed source driver, and thus is quite useless :-( I was stupid enought to think "Works with RHEL and SuSE" meant "Certified for RHEL and SuSE, but driver in mainstream kernel" ..
What SAS (or SATA) controller do you use or recommend in combination with a SSD and BTRFS?
I'm looking for a non-RAID controller with four or eight ports and of course full Linux support.
Currently I have a 8x 2.5" SAS/SATA chassis and two Intel X25-E 64GB drivers which will have a BTRFS RAID0 filesystem.
I already have a Marvell MV88SX6081 eight port SATA controller, but it has no free ports and is pretty old.
With kind regards, Sander

try this. they're supposed to be good, so long that you don't need =20 "hardware" RAID. Sun uses the same chipset in their opensolaris-based =20 storage solution

That is the AOC-SAT2-MV8 which I have indeed :-) (is listed as MV88SX6081 with lspci).
Works pretty well btw, but all eight ports are filled hence the search for a new one. Preferably a newer generation with better specs.
The Areca ARC-1300-4i listed on
http://www.areca.us/products/sasnoneraid.htm looks interesting, as is the AOC-SASLP-MV8 listed on

Thanks a lot for your input!
With kind regards, Sander

Hi,
I don't have any ssd yet, but if you want cheap card without hardware raid, you could look at those :

http://www.supermicro.com/products/accessories/addon/AOC-USAS-L8i.cfm
You'll need to revert the bracket as they're designed to be in a supermicro UIO slot (In fact, they are just standart PCIe card upside down). They use the mptsas driver in linux which works ok for a long time, and can be found for ~ 130$. It work pretty fast (~ 800 Mo/s with a 8 drives raid10f2 in my brand new nehalem server).
You can also find this one for ~ 120 bucks :

No proprietary slot this time, the chipset is supported in 2.6.30 (but = I
haven't tested it yet) via the mvsas drivers.
Hope you find this usefull.

Very useful, much appreciated, thanks!
I think I go for a Marvell based controller (again), as Marvell chips seem to have quite a history when it comes to open source drivers.
No more Adaptec ..
Thanks again Sebastien.
With kind regards, Sander

I am very happy with all my Adaptec gear plus drivers are in Mainline since 2.4. Also, Adaptec is up and about to start packaging ASM (Adaptec Storage Manager) etc. for Debian and its offsprings afaict:
