Some initial test results...
I installed an old Infinihost DDR HCA in one of our compute nodes
running FreeBSD 9.1.
RHEL nodes are using qlogic IB HCAs.
10.1.1 is gigabit Ethernet, 10.1.2 is IB.
Running iperf server on FreeBSD and client on one of our RHEL nodes
shows OK performance:
bacon@infinibsd:/home/bacon % iperf -s
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 64.0 KByte (default)
------------------------------------------------------------
[ 4] local 10.1.1.140 port 5001 connected with 10.1.1.39 port 35947
[ ID] Interval Transfer Bandwidth
[ 4] 0.0-10.0 sec 1.10 GBytes 947 Mbits/sec
[ 5] local 10.1.2.140 port 5001 connected with 10.1.2.39 port 60090
[ 5] 0.0-10.0 sec 7.20 GBytes 6.18 Gbits/sec
RHEL to RHEL gives us about 8 Gbits/sec.
Iperf server on RHEL and client on FreeBSD shows very poor performance
for IB, while GigE is fine:
bacon@infinibsd:/home/bacon % iperf -c 10.1.1.39
------------------------------------------------------------
Client connecting to 10.1.1.39, TCP port 5001
TCP window size: 32.8 KByte (default)
------------------------------------------------------------
[ 3] local 10.1.1.140 port 60066 connected with 10.1.1.39 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 1.10 GBytes 943 Mbits/sec
bacon@infinibsd:/home/bacon % iperf -c 10.1.2.39
------------------------------------------------------------
Client connecting to 10.1.2.39, TCP port 5001
TCP window size: 32.0 KByte (default)
------------------------------------------------------------
[ 3] local 10.1.2.140 port 14608 connected with 10.1.2.39 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-32.7 sec 768 KBytes 192 Kbits/sec
Any ideas what might cause this?
I'm going to install 9.2-RELEASE and retest in any case, plus explore
the ib config tools, but any feedback in the meantime would be appreciated.
Thanks,
JB
