Hello,
I've started with my second Freenas system this week, this time not FC-target but 10Gbe cards.
I'm not satisfied with the performance of the system.
Server specs:
Dell r520 server with 128GB Ram
8x Samsung PM883 480GB Connected to PCI-E Dell Perc H310 (IT-Mode)
Freenas 11.3 (latest version)
Chelsio n320e (dual port)
I'v created 4x vdev Mirrored,
On the remote system I installed also a Chelsio n320e (dual port / Multipath enabled) and connected both ports to the freenas server. (MTU=9000)
Chelsio card have both a 2x IP in a different subnet
MTU=1500 and MTU=9000 tested on both systems no difference
Iperf tested both SFP's with 9,8 Gbps (so the card are working at maximum speed)
I can mount the ISCSI drives perfect (multipath /dev/mapper) , created a speedtest.sh file and receive 400MB writing en 800 MB reading,
Is this the best speed I can get? I was thinking it should be a lot more?
I'm I doing something wrong? Any suggestions or welcome...
