Proware SB-3164E-G1A3 (da0: Fixed Direct Access SCSI-4 device) 2. Infortrend ES-A12E-G2121 (da1: Fixed Direct Access SCSI-5 device) 3. Promise VTrak M610i (da2: 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? Our iSCSI initiator MIBs are http://free.cc.kmu.edu.tw/iscsi/iscsi-mibs.txt Our FreeBSD 7.2-R dmesg is http://free.cc.kmu.edu.tw/iscsi/dmesg.txt The iscsi.conf is http://free.cc.kmu.edu.tw/iscsi/iscsi-conf.txt The iscontrol verbose messages are http://free.cc.kmu.edu.tw/iscsi/iscontrol-v.txt Thank you in advance.

After we use iperf to measure the performance of GbE NIC/Switch, we replace a GbE switch to re-run the original tests. Finally we get steady throughputs for all the 3 iSCSI targets. Thanks to Danny again.
