PCI-E SATA-III HBA for FreeBSD 10

Roger,

Try P19 firmware in IT mode.  I just moved a bunch of drives to 9211-8i's and had similar problems with P20 firmware.

Downgrading to P19 resolved the issue for me.

I would have posted to the list like you but the server changes were in the middle of the night and I needed a quick resolution.

Report back!

I have followed this suggestion and bought an LSI SAS 9211-4i (SAS2004)
board and flashed it with the "IT" firmware after installation into my
HP N40L microserver.  It's being detected at boot and also finding the
attached SSDs, but I'm getting a lot of strange errors.  Could anyone
suggest what might be at fault here?

The board has an SFF-8087 breakout cable attached which has 4 SATA
connectors which are plugged into a SATA backplane.  This has 3
SATA-III SSDs installed into it:
- a Crucial M550 256GB SATA-III drive
- 2x Trancend SSD370 64GB SATA-III drives

The server is now running 10.1-RELEASE.  At boot I get some SATA errors,
and when running "diskutil -t" or "dd" I get screeds of errors in the
kernel logs, and the "dd" I/O throughput is in the low 10s of Mb/s
rather than ~400+ as expected.  Booting with an Ubuntu 10.10 live USB
drive gives the expected throughput for the Transcend drives with zero
errors, while I still get some errors for the Crucial SSD.  Google
suggests that this might be due to using SATA drives rather than SAS
which don't do tagged command queuing, but not sure if this applies
here.  Are there any mpt/da or other settings which need tweaking to
work with SATA-III drives?

Not sure if this is a hardware/cable/drive/kernel driver fault, but
I've tested the SSDs in a different system where they work perfectly
(they are brand new).  Given the difference in behaviour with Ubuntu it
looks like it might be the mps/da drivers, but not entirely sure.


Thanks,
Roger
