Running Raid Z2 via a IT MODE HBA freenas RAID CARD controller Fujitsu D2607-A21 8i
I'm currently transfering across approx 8TB over a 10GB connection using SMB, I started off at around 170MB/s ( I dont have any cache SSD's, just using hdd's) and after about 10 minutes this has dropped to around 25-35 MB's. Anything that can be causing this? Not sure if cache is enabled on the HBA controller or if you even can use cache now its in IT mode, I cant seem to access any firmware on it during boot. If I pause the transfer and start it up a few minutes later I get good transfer speeds again until it drops off shortly after.
I have just ran an iperf test and am getting 2.31 Gbits/sec. Using two emulex oneconnect oce 1102-n-x cards. No drivers have been installed for the network cards on either machine, one on windows 10 and one TrueNas
No other machine is transfering anything to the Nas.
Pool is set as lz4, raidz2 currently with x4 8TB's (more to be added)
checksum on
acl mode passthrough
sync standard
enable atime off
any help would be appreciated
