I have 3 2012 std (all 2012 on this network) servers setup as such:
4 nics going to a virtual server on 2 vm hosts
8 nics going to a sofs server
All clustered together to host ad/dhcp/dns/filesharing
cisco switches, all lacp setup and verified.
Tried using Intel's NIC teaming (these are the top of the line 1GB intel nics)
Tried using the OS's SMB teaming.
Either way when I transfer files from my SoFS share to inside a VM, I get crap speeds. 30MB-50MB/sec, instead of 110+MB/sec.
At first I was getting speeds in the KB range until I changed the (Get-Cluster).BlockCacheSize to something like 4GB, so that helped quite a bit.
I can transfer a file to the node/host from the sofs file share and max out at 113MB/sec just fine.
I cannot seem to figure out what is causing this.
I've turned off RSS, and Queueing while under SMB team and Intel team and got nearly the same results.
Does anyone know what could cause this?
Also can someone tell me this, with the newest SMB 3.2 and multiple nics in LACP with SMB multichannel, am I able to get a 2+2=4 effect with the bandwidth? Or is this just some nifty new feature to prevent downtime when a nic suddenly dies?
