¿Why my iscsi speed is like limited?

an update:
i have setup raid 0 for speed test but i still have the same performance, I do not know which is the bottleneck in my setup.

thanks

Another update:

The previous tests were made with the target configured in File I/O mode with WB enabled.
I ran test with WB disable, also in the controller WB was disabled but the performance was too slow.

Recently i have configured the DSS V6 Lite with Block I/O with WB enabled. Now i have a better performance but it still slow.

Esxi says that the nics are transmitting about 30.000 Kbps each.

What other test I can do to figure out what is the problem?

Thanks!

try upgrading to latest V6 b5087, and switch to SCST1.0

Gr-R:


I´m already using DSS V6: 6.0up55.8101.5087 64bit and SCST1.0.

The strange thing is that i can move a 41 Gb archive from the esxi to the DSS V6 in less than 10 minutes but, in a VM, IOmeter shows 25 Mb maximun.

I don´t know if is the processor (athlonII x2 245, 2.9 ghz) is my bottleneck:



Thanks!!!

Hmm your using a desktop adapter for your MPIO I would carefully check your specs on these adapters. Not saying there is an issue here, just I wouldn't use desktop cards for anything intensive and iSCSI MPIO, the rest of your esxi settings look right.

What is your switch equipment? Have you check packet through put on your switches etc

Now i am using crossover cable between the Open-E and the esxi.
But if u want to know this is my switch:

I will try to upgrade the processor and see if the performance improves.

Thanks!

OK.
I have upgraded to a Quad Core CPU (intel Q8300) with 4 GB of ram and a mobo with intel chipset (Don´t remember wich one).

The performance is even worst!!!

I only have a maximun of 15.000 Kbps on each Nic and a total usage of 28647 kbps (according the esxi graphics)

I give up with this. Tomorrow i think that i will go back to Openfiler.

Thank you all!!!
