Hey, I'm looking at building a couple of unraid servers.  I can't seem to find anywhere online whether unraid supports SMB 3.0 Multi channel.  I've got a setup at home that I'm looking at converting to unraid and another system at work that I'm looking to build.  I like the ease of management and configuration so that I can pass the reins to someone else when I leave.  The use case is a bunch of students editing video off one central NAS , and I wanted to use SMB multi channel to achieve high enough transfer speeds to do this.  If I need to run a windows VM, that's fine.  I was planning on running a Windows Server VM for DNS and logon purposes.  Thanks for your help, Micah.

Add more info.

I have split your post into its own topic. The FAQ topic really should only contain posts that are actual additions to the FAQ.

Okay, sorry about that.  I'm sorta new here, and I figured that SMB multi channel need to be there.

Samba supports SMB multichannel, though last I heard it's still considered experimental, not for production

Okay.  Do you know if it would be possible to pass the storage pool and the two network cards into a windows VM?  That would give me native support.

You can passthrough NICs and disks, but not the main array, that can only be used with vdisks, and those won't generally perform great on the parity protected array, they can perform well on the cache pool.

Can you make a virtual 10 Gb link between the unraid os and the VM?  Is there a better multi channel file implementation in a different protocol?  I'm just trying to make sure that this setup would actually work.   

In looking into it, I may just go with a 10 gb nic.  Thanks for your help, Micah!

Technically the link between the unraid server and the vm are whatever the speed is(figure there is a max somewhere) because its an internal to the server switch. Much like VMware.. Though I will say unless you are putting everything on SSDs or have a large cache drive your just not going to get massive performance like you would with say ZFS.

This would be the best option, and if you just need one or two computers connected to the server at these speeds you can use a peer to peer connection, this can done very inexpensively with used NICs.

It's going to be connected for around 15 computers, and the place this is going into has 10gb ethernet in a server room, with gigabit to each of the computers, giving me acceptable bandwidth.
