Configuring vMotion on ESXi to use multiple NIC ?

Hi All,

I'm using single ESXi 5.5 U3 servers with 2x NICS connected to 2x NICs at the QNAP TVS-471 NAS,

At the moment I can see that when running svMotion, it only uses one cable or one path only ?

How to configure it so that it uses both path for additional throughout ?

Thanks.

You configure exactly the same as you would multipath iSCSI like my EE Article

HOW TO: Add an iSCSI Software Adaptor and Create an iSCSI Multipath Network in VMware vSphere Hypervisor ESXi 5.0

also enable Jumbo Frames

HOW TO: Enable Jumbo Frames on a VMware vSphere Hypervisor (ESXi 5.0) host server using the VMware vSphere Client

BUT one thing you do NOT need to do, is the iSCSI Bindings. Label accordingly e.g. vMotion#1, vMotion#2, make sure the override is also set, to if one path fails, the other continues.

if you like you can also VLAN Tag, but make sure the vMotion network is isolated, different VLAN, or private network.

and check using vmkping, that you can ping all the vMotion nics. using vmkping with correct syntax to send packets through the correct vmnics.

okay, what are we trying to do here ?

do you only have 2 nics available to to iSCSI and vMotion ?

so have you now changed your iSCSI network from above screenshot ?

ok, here's what I'm trying to do:

ESXi server:
1x NIC for server management traffic
2x iSCSI connection for Data
1x free unused

1x iLO

QNAP TVS-471 NAS:
1x NIC for NAS management traffic
2x iSCSI connection for Data
1x free unused

Okay, this is what I would suggest is...

completely remove the existing iSCSI vSwitch.

Setup from scratch as per my document, follow it step by step with screenshots.

then we can discuss, vMotion as this what this question was originally posted and about.
