We appear to be getting very poor performance out of our 2 PowerEdge R905 Perc 6i cards (lots of iowait, iostat showing slow read and write speeds). We have 2 SAS drives setup in a second mirror set and have upgraded our mptlinux version to 4.18.00.00.
Fusion MPT base driver
Fusion MPT SPI host driver
Fusion MPT FC host driver
Fusion MPT SAS host driver
Fusion MPT ioctl driver
lsiutil shows the following:
1 MPT Port found
Port Name Chip Vendor/Type/Rev MPT Rev Firmware Rev IOC
1. /proc/mpt/ioc0 LSI Logic SAS1068E B3 105 00143000 0
Current active firmware version is 00143000 (0.20.48)
Firmware image's version is MPTFW-00.20.48.00-IE
x86 BIOS image's version is MPTBIOS-6.14.10.00 (2007.09.29)
I've looked around but can't see any updated firmware for this setup. Does anyone have any thoughts about how I could go about investigating this further?
We're running Gentoo Linux kernel revision 2.6.27.
Thanks & Regards,
