Question

Hi everyone,

I wanted to pose a question to see if anyone has managed to get MPIO working with any version of Windows 10's iscsi initiator. With Server 2016 available, I wanted to see if it was feasible to "enable" MPIO in Windows 10 using a method similar to http://answers.microsoft.com/en-us/windows/forum/windows_other-update/i-want-to-use-mpio-with-ms-iscsi-initiator-how-to/fac32233-1517-4d0c-9155-dde111ae1a83 (I am in the process of getting my account verified so I can post proper links...). I can get MCS working, but unfortunately, my iscsi target can only support two connections per session and I have potential need of four.

Thanks!

You can configure MPIO in Windows 10 but it is disabled on the next reboot.   You may be able to get mpio through 3rd party but I don't know of any for Win10

Hi

I managed to "transplant" MPIO and msdsm driver from Windows 2019 to Windows 10 Pro (1703, 1709, 1803 and 1809) with success.
The method needs to import some registry, copy necessary files into original place and manually check update for drivers.
There was slow and old Infortrend Disk Array in my test (3x Gig connected to switch with 10Gig to PC), so PC initiated 3 paths from 1x10Gig to 3x1Gig

But in fast PC + fast array (4x1Gig Array + 4x1Gig PC) it performs like this

How-to and script+files+registry are located inside zip file (link below).

Beware!!! Backup first and this "mod" is for test/educational purpose only. You do it at your own risk and take the responsibility upon yourself and you are not to blame me.
