Fiber Channel r/w speed results?

[r3vo]

well, I couldn't resolve the problem in the past. Do you have the same problems if you connect with 4gbit instead of 8gbit?
Which release do you have installed?
ATM i got a stable connection with 4Gbit, without any performance loss.

@R3vo
Thanks for the answer.
I am using dss V6 latest version.
My connection between the fc cards adjusted auto. i will try with 4 gb then write here the result.

I tried with 4gb on both sides but no difference. Target dssv6 uses qle2562 and initiator macpro uses atto fc en82. At target side i have only 2 gb ram. can it be the reason of poor performance. Or atto and qlogic does not like each other? I tried several settings on fc cards. if i choose only Point to point connection no connection (only loop works) frame size doesnt make any difference (512-1024-2048) What can i do more without replacing atto card with another qlogic2562.

Well, in the past i can't resolve the problem. I installed my Server2008 and the DSSv6 new due to testing reasons.
ATM I got no connection problems. I dont think its caused by the memory. I got 8GB RAM installed and had the same problem like you.
I am working now with two 2562. In the past i was using an 2562 and 2462 Controller. I cant say if two different cards cause the problem.

I think you already have the latest drivers installed on your MAC Pro?

i updated atto fc en82 driver, bios, manager etc.. Everything is uptated. On open-e side qle2562 bios was 2.02 then updated it too 2.10. I started to believe that atto and qlogic cards does not like each other. Even in your sample two different qlogic cards (2562-2462) could not work together...

Finally we did it. Problem was raid5. We destroy raid and replaced by raid50. Now reading is 700 mb/s. Writing is arround 280 mb/s. Also if the client macpro has macos 10.5.7 everthing is ok with 700 mb/s reading and 280 mb/s writing. When we update macpro to 10.6.2 (snow leopard) reading is 300 mb/s writing is 300 mb/s without any problem.
Thanks for your help @r3Vo.
