50MBps write and 6.5MBps read to/from enterprise HDD18TB and NVMe drive too! Over SMB from W10P
No parity so far, only two disks:
18TB Ultrastar HDD for data Disk 1WDC_WUH721818ALE6L4

920GB cache SAMSUNG_MZ1LB960HAJQ-00007 - 960 GB (nvme0n1)

 

I have one SMB share with cache disabled (same problem for cache-iso folder).
When I write to it (one, big file) I expect 113MBps, I have 50MBps. When I read, I expect 113MBPs and I have... 6.5MBps.
Any ideas? My setup is very similar to:

I use encryption on both array and cache.

Your evidence suggets that it's a network problem.

 

I see you have two 1 Gb/s links bonded in mode 6, which is good for up to 1 Gb/s to a single client. How is your Windows client connected? WiFi? 100 Mb/s Ethernet?

 

I tried non-bond, fail-over bond, mode 6 bond. Nothing changed.
EDIT: Tested on 1NIC only, no changes. I'll check it on Mellanox soon.

SMB3_11. But please note, I can download files via http, I have 6.5MBps too!
Windows SMB write speed (not under unRAID, did W10P test install😞

Next step will be OMV installation to troubleshoot Linux environment. Maybe older unRAID too...
After the holidays I'll use Mellanox NIC instead of Intel to troubleshoot.

OK, it looks like we have an answer:

Next week I have 1GBps connectors for my Mellanox, so 95% problem will be solved.

There is actually a bug on this board that you may not have noticed yet, but RX traffic on the network adapters with the specific version of the firmware/BIOS is actually degrading the network performance to 1/3 of the speed. Again, only on RX.

 

I have already raised this issue with Asrock Rack and they have confirmed the issue with a specific AMD driver combination after many many emails and actually sending my board back.

 

A friend of mine has the X570D4U-2L2T and doesn't have this issue, so its only for the X570D4U where the firmware has been affected.

On that matter, PLEASE, everyone that has this problem, open a support ticket on Asrock so they know there are more people interested in a fix.

for the serial number, just copy it from IPMI.

Use iperf3 to test network speeds. You can use NerdPack to install it on Unraid. It's available for other OSes too, including Windows.

 

I can confirm, that Mellanox3 (1GB connectors) on exact same settings saturates 1GB link easily.
So, I confirm Asrock bug!
