bmac6996 Posted June 28, 2018 Share Posted June 28, 2018 Hi I recently added a single 10gb Mellanox NIC card to my Unraid server and my Freenas server. As a test I'm trying to see if i can hit that mark. I'm not getting anywhere close to it. This is how I'm testing: On the unraid server, i have a single SSD cache drive (rated 500MBs). SSD is connected to a 2308 LSI controller (IT mode). A windows 10 VM on it. Network settings in the VM and in Unraid has MTU to 9000. Freenas server has a two intel ssds (also rated 500 MBs) set for Stripping. SSD is connected to a 2308 LSI controller (IT mode). Created a share on it. MTU is set to 9000. Setup these tunable options per the internet to optimize settings: (enter via CLI and even rebooted) sysctl kern.ipc.somaxconn=2048 sysctl kern.ipc.maxsockbuf=16777216 sysctl net.inet.tcp.recvspace=4194304 sysctl net.inet.tcp.sendspace=2097152 sysctl net.inet.tcp.sendbuf_max=16777216 sysctl net.inet.tcp.recvbuf_max=16777216 sysctl net.inet.tcp.sendbuf_inc=32768 sysctl net.inet.tcp.recvbuf_inc=524288 sysctl net.route.netisr_maxqlen=2048 I tested by coping a big file between the VM in cache and the share on freenas. Maybe i hit 500 MBs according to Windows copying GUI but it didn't last very long. On average i'm getting anywhere between 150 - 200 MBs. Then I tried iperf. Setup the freenas as the server and the VM as the client. Ran the tests a bunch of times and basically getting about the same. Based on my Hardware and setup, is this the MAX I can get? In order to get the 10gb transfer speeds, are do i need a nvme on an m2 in order to get that type of transfer? is the sata SSDs the bottleneck? Thoughts? Thanks in advance!! Quote Link to comment
