G5 NC373i Performance issues

[ChrisPSynergy]

Hi,
We have a G5 with performance issues between 1000/100.

Anything via 1GB is fine - anything going to or from 100mb seems to be causing problems.

Is there anything which can be suggested?

I've got a few out of hours ideas to try but I am eager to know if there is anything anyone can suggest.

Thanks,

Chris

Are you seeing anything out of the ordinary in the HP NCU (Network Configuration Utility) -> Properties -> Statistics -> Advanced? Any Overruns, CRC errors, Alignment errors, collisions, etcetera?

I see that you've listed the generation of server. Which model?

Which OS? x86 or x64?

Is the Speed/Duplex set to Auto/Auto?

This was resolved.

Diagnostics revealed problems with the EEPROM and disableing TCP Offload has resolved the problem.

We are going to try new firmware and see if that resolves the issues.

Was wondering if you got this resolved? We are seeing same ting, NC373i on DL385 G2 or DL380 G5 when Win 2003 and SP2 with PSP 7.9 and TOE enabled we get TOE erros and conncections fails, always seem to be when 1gb is talking to 100mb. 1gb to 1gb seems to work. Nice incentive to upgare entire network ;-)

Hi Guys,

I'm experiencing pretty much the same issue here, difference is that I get random loss of connectivity (not reported by the NIC), my configuration is using 100Mb full duplex, same as switch. I have other servers with same specs and config on the same rack and I don't have any problems.
Any idea?

Cheers,

Hi

I also have same kind of problem. My server is ML370 G5 with NC373i and it randomly (at least once a week) disappears from network. There is nothing informations in event logs. I have examined that it always happens when backup job over network begins at night and network traffic increases greatly. Does anyone knows if there is some kind of workaround (network adapter settings etc.). I have updated latest network firmware and MS drivers without any help. Both server adapter and switch port has been configured 100 Mbps/Full.

There is an issue with certain nics and the TCP Offloading feature.

Please see the following article.

I have a BL460C with a NC373i NIC which becomes unresponsive to network connections about once a week (seemingly at random.) It has to be rebooted to bring it back online. This behavior usually is accompanied by 8021 and 8032 errors in the system log. Do you think it could be related to the offload "feature" mentioned in this thread?

I am having issues also with HPNC373i nic card speed being 4 times slow to upload large SQL tables than a Dell NIC card. Besides changing the three registry's setting to 0,
EnableRSS = 0
EnableTCPA = 0
EnableTCPChimney = 0

Once we changed the NIC card setting to
Checksum Offload = NONE
Large Send Offload = DISABLE
Receive Side Scaling = DISABLE
The speed was doubled. Still looking at firmware or HP NCU utility to increase it more.

Hi Chris,

In one of your comment on this forum you said that diagnostic revealed that EEPROM has the problem with TOE features. What test did you do to come to conclusion that EEPROM has the problem and how?

We have DL360 G5 serevrs is production which has connectivity issues from client after weekly reboot. The NIC used to connect to the client is NC373i. We are trying to reproduce the issue but with no luck. Also we see lots of CRC/frame errors on the switch port connected to this NIC. Any help is much appreciated. Thank you.

Regards,
