Hi guys!
First of all, my first post here!!!
I was trying to use a replaced motherboard to try to make some lab environment for Windows Server Hyper-V 2012.
I've follow the very nice guide : https://forums.freenas.org/index.php?threads/freenas-9-3-fc-fibre-channel-target-mode-das-san.27653/
The setup :
1x Brocade 200E 4GB
1x Gigabyte z87 Motherboard 4GB RAM DDR3 CPU Celeron G1820 + 1SSD 250 Samsung Evo 840 + Qlogic FC QLE2464 (Quad Port FC 4GB) - Installed with Freenas 9.3.1 and booting from a USB 8GB drive
I haven't follow some of the recommended guidelines, so, Im initially guessing that the slow performance is from there (specially from RAM, but I will try to upgrade this afternoon and see if I get better results).
And everything worked fine, like a charm indeed I can see the storage from another PC (using a Emulex 4GB LPe1150). The problem is in fact in the performance, using the ATTO disk benchmark on the new SAN volume I can only get around 200MB/sec. If the FC card is 4GB, shouldn't be more close to the 400mb/sec?
Having in mind that the SSD is not a bottleneck, Im only guessing the FC card is the bottleneck here, but still dont know why.
And another thing, I get the same speed using 1 FC cable connected than two. I've installed MPIO on windows Server 2012 R2, but, still the same performance.
My next step will be upgrading the memory from 4GB to 16GB and see if I get better performance.
Anything else I should check for that performance improvement?
Should the MPIO through iscsi should work by default?
Cheers and thanks!!!
