Hi.
I've encountered a very annoying issue with my setup: Since sometime (I have no idea when or why) I've lost nearly all my write IOPS through my LSI 9207-8i and SAS2x36 backplane.
This is the result of the sas2flash -list:
..and this is the benchmark of a single Samsung 840 Evo through the 9207-8i and the SAS2x36 backplane:
... and this is the same disk connected to the onboard SATA controller:
I have tried every controller firmware from P15 (with a proper clean) to P20 with the exact same results.
Unfortunately, I miss a SAS breakout cable so I have no means of bypassing the backplane for further troubleshooting.
Any tips before I order myself a breakout cable for further troubleshooting?
Cheers
