Hello all,

We have tested 3 iSCSI targets with initiator 2.1.0 on FreeBSD 7.2-R:

1. Proware SB-3164E-G1A3 (da0: <proIPS__ SB-3164E-G1A3 1.0.> Fixed 
Direct Access SCSI-4 device)

2. Infortrend ES-A12E-G2121 (da1: <IFT ES-A12E-G2121 361G> Fixed Direct 
Access SCSI-5 device)

3. Promise VTrak M610i (da2: <Promise VTrak M610i 021D> Fixed Direct 
Access SCSI-5 device)

Our tests are dd if=/dev/random of=${iSCSI_TARGET_DIR}/bigf bs=1024k 
count=1000

and use iostat to see the I/O throughputs of each iSCSI targets.

The results are at  http://free.cc.kmu.edu.tw/iscsi/iotest.txt

We see that the throughputs of Promise VTrak M610i are much more steady 
than others.

(da2 is much steady than da0 and da1)

Could we tune something to make Proware SB-3164E-G1A3 and Infortrend 
ES-A12E-G2121

more steady?
