Hi
I have got very similar problems. The same SAS-Controllor (LSI2008) connects my Server (Fujitsu TX150 S8) to an external Storage (Fujitsu ETERNUS). Performance seems to be OK but I see many entries in the vmkernel logs. Fujitsu advised me to change the SAS-Controller ... the failure remains. I have got three identical systems runnung on the same hardware configuration. All three systems show the failures in the kernel logs. On systeme craches about one time a week showing a purple screen.
The kernel log looks like this:
2013-07-09T16:27:55.760Z cpu4:4650)NMP: nmp_ThrottleLogForDevice:2319: Cmd 0x1a (0x412400735200, 0) to dev "mpx.vmhba0:C0:T0:L0" on path "vmhba0:C0:T0:L0" Failed: H:0x0 D:0x2 P:0x0 Valid sense data: 0x5 0x20 0x0. Act:NONE

Thanks for any help!
