Offtopic: Which SAS / SATA HBA do you recommend?

[Sander]

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

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
http://www.supermicro.com/products/accessories/addon/AOC-SASLP-MV8.cfm

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-USASLP-L8i.cfm
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 :
http://www.supermicro.com/products/accessories/addon/AOC-SASLP-MV8.cfm

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.

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:
