Two companies have a dedicated T1 between their offices,
at company A there is one OSR 5.0.7 system (A1),
at company B there are two OSR 5.0.7 (B1 and B2) and one OSR 5.0.6 (B3).
The A1, B1 and B2 are the same HP ML380s, the B3 is older HP h/w
There is a ftp-based data exchange established between system at A and all three systems at B.
The speed between A1 / B1 and A1 / B2 is around 55 Kbytes/s; the speed between A1 and B3 is around 220 Kbytes/s.
The routing scheme at company B is the same on all three boxes. The B2 and B3 are on the same subnet, B1 is on another subnet. The load on B3 is actually the highest of those three at company B.
I can't understand how is the older and fully loaded system achieves 3 times higher speed.
What should I check and tweak to ensure all three systems from B would get the same 200+ Kbytes/s speed?
sorry for the late reply, the systems are not readily accesable to me.
I will try to answer the questions here
- network cards are configured to be auto on speed and on flow control
- one single switch used for B1, B2 and B3
- one firewall for the whole B company, no specific configs for the OSR systems
- don't know how to get errors on the network, should I just run
the output is quite lengthy, which section should I post here?
- traceroute outputs:
From B1 to A (slow)
From B3 to A (fast)
They look very similar to me.
Please tell me what else is needed to pinpoint the problem?
Thanks in advance.
Output from netstat -s would be good to see, even if it is a bit long.
Do you have a problem in FTP speed when you compare speeds just within company B?
We had a problem once where the auto-negotiation was wrong and we had a switch at 100M-Full duplex with a servers at 10M-Half. It all worked fine until we forced lots of data with an FTP, so it was difficult to track down.
You might need to ask the network manager to display the switch ports settings. You may be able to give IP address, or they may require the MAC address of your network card.
I regret I do not know how to display the requested and negotiated speeds on OSR. Can anyone else chip in?
I have been wondering how do Systems Administrators do the jump into Systems Engineering? Is it only a matter of time and experience or could I actually help myself get there?
Opinions? Books I could read?
Thanks a lot for your help! (0 Replies)
