Hello. I'm struggling a IBM x336 machine with FustionMPT LSI53C1030.
This controller can't do radi0 so I disabled raid in the BIOS.
Problem is that disks are detected wrong and IO is very slow
hdparm -t gives only 37MB/s
dmesg shows that both disks are recognized as FAST-20 while it should be
FAST-160. also cache is disabled.
I've googled around for hours, saw many problems related to the MPT being
slow when compiled into the kernel in old versions (I have tried module) but
I'm using using 2.6.31.
Here are some logs:

Well, the cache is easy, it isn't disabled, it's set to read through
(the correct setting for enterprise disks). That's what write
disabled, read enabled means.

This is more curious, it seems to indicate that the disk is reporting
its max transfer period as 50ns. Try raising it by echoing 25 to
min_period and then 1 to revalidate to force a renegotiation.

Hello James and thanks for trying to help.
Unfortunately changing min_period didn't solve anything.
# pwd
/sys/class/spi_transport/target2:0:1
localhost target2:0:1 # echo 25 > min_period
localhost target2:0:1 # echo 1 > revalidate
I did it for both disks.
#dmesg | tail -10

# cat period

hdparm still shows the same results.
# hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 1734 MB in 2.00 seconds = 867.28 MB/sec
Timing buffered disk reads: 114 MB in 3.04 seconds = 37.55 MB/sec
# hdparm -Tt /dev/sdb
/dev/sdb:
Timing cached reads: 1732 MB in 2.00 seconds = 866.42 MB/sec
Timing buffered disk reads: 114 MB in 3.04 seconds = 37.47 MB/sec

OK, so I'd suspect a cabling problem. 50ns is the minimum period for a
single ended bus. You have to move to LVD to get anything beyond. I'd
say something in your SCSI cable chain is keeping the bus SE.

Well I opened the server. nothing much to play with everything is tied up and
I don't think anything except maybe disks has been changed since this server
was bought.
Can It be related to disk jumper settings ? Anything else you can think of ?
