I have a fas 8060 cluster 8.3.2 with FC connection LACP 10 g. By the client side we use Ubuntu 14.4 NFS shares. When I test my connection with fio performance test the iops and disk IO workloads I have low througputs than I had expected. I have attached the outputs from sysstat -x , port utilizations and perfstat during the process to the message.
I have 800-900 mb/s with 1 client and 1100-1200 mb/s with 2 client connections. But this values has decreased dramatically to 500-600 mb/s in a few minutes. I am not waiting 2gb/s
throughput but this values is unacceptable. I have already checked the switch,cabling,etc. but I didn't find any solution. I have moved the volume to SAS and SSD but I have the same result.
Can someone help me? I dont know was I will exact looking or testing?
