Hi there, 

I have an MD3260i we are setting up as a Backup repository. It is attached to a Windows 2019 server virtual machine via iSCSI direct from the Windows server. We're having performance issues with writes to the disks provided by the MD3260i, such that we get about 17MBytes/Sec write, but 400 MBytes/sec read. 

We have Jumbo frames enabled end-to-end, and the Disk Group on the MD is a Raid10 group. Are there more specific settings I can tweak to improve performance? 

It's not in production yet, so if I need to tear things down and rebuild them I can do so

Thanks,

James
