Re: Poor throughput using Etherchannel and 802.3ad bond

Hey, not sure if this is helpful or not but I'm seeing something similar.

With my windows 2008 box being the server and my SAN being the client I can achive 890Mbs which isn't too bad.

However, when we turn the tables and make the SAN the server and the client my Windows 2008 box I can only achive 390Mbs.

Woah that confused me.  Do you mean running iperf as a client/server?

Is your SAN busy responding to lots of other 'clients' or hosting some Network Raid 5 volumes?

Re: Poor throughput using Etherchannel and 802.3ad bond

Sorry for the delayed response.  Basically it was the following:

 

Test 1)
Windows 2008 box as iperf Server -  P4000 Lefthand Node as Client: Maximum 380Mb/s Throughput.

 

Test 2)

P4000 Lefthand Node as Server - Windows 2008 box as Client: 940Mb/s Throughput.

 

 

For some reason when you flip the tables and make a connecting box the server and the SAN the client the performance degrades drastically, have you tried a similar test?  Also, there's no IO at all going on with the SAN.
