I am having trouble deciding if I should go with SUM or MIN mode. Here is my config info:
2 Dell R620 host servers - Each server has 128G RAM, 12 NICs, 2 CPUs.
Here is the result of the processor script:
PS C:\Windows\system32> Get-WmiObject -Class win32_processor | format-table -Property NumberOfCores, NumberOfLogicalProcessors -AutoSize
NumberOfCores NumberOfLogicalProcessors
------------- -------------------------
6 12
6 12
I am using 2 of the NIC ports of each server for dedicated iSCSI to my EQL. The other 10 are in a team. The team settings are currently Switch Independent and Address Hash, No Standby adapter.
I tried Load balancing mode: Hyper V Port (SUM mode) but kept getting errors in my event log about overlapping. It seems like SUM mode is the best way to go but how can I properly set up 10 NICs with the 2 processors (6 cores and 12 logical processors each) to not overlap?
Is it even worth using VMQ with just 2 host servers? We plan on eventually running about 6-8 VMs on each host. Also someone told me that Live Migration only uses the first NIC port, even if they are teamed, to move VMs if you are in a 2 node cluster. I'm not sure if this is true but in Task Manager, the network activity never goes much above 1G when migrating 3 VMs simultaneously.
Some additional info on our v-nics and vlans:
PS C:\Windows\system32> Get-VMNetworkAdapterVlan
VMName VMNetworkAdapterName Mode VlanList
------ -------------------- ---- --------
LiveMigration
Access 102
Cluster
Access 101
Management
Access 90
BaseInstall-2012R2Std Network Adapter Untagged
BPD-IT7 Network Adapter Untagged
The minimum bandwidth QOS weights are LM = 25, Cluster = 25 and Mgmt = 15
I have the VM traffic using the v-switch that these v-nics are assigned to. I have the "DefaultFlowMinimumBandwidthWeight" set on the switch to 35.
Thanks for any help.
