VMotion with ISCSI

[davemayo]

Hi All,

I am doing my first vSphere deployment and I have a question about the networking requirements for VMotion. I currently have 1 Physical Switch with the iSCSI traffic VLAN'd to reduce broadcast storms. We will be getting a second switch at a later date.

I have an EqualLogic PS4000XV SAN it has 2 active 1Gbps ethernet ports on it. And 1 management port. I have read that if it best to assign another VLAN to dedicate to VMotion, my question is, do I need to assign 1 port on the SAN to the ISCSI VLAN and another port on the SAN to the VMotion VLAN? Because I would prefer to keep them on the same VLAN so I can LAG them together for some extra speed.

vmotion traffic is between the vmkernel ports configured for vmotion - there will never need to be any traffic to the SAN - you will need to configure the ports your physical NIC connects to as a trunk so it can recognize both the iSCSI vlan and the vmotion vlan -

If you find this or any other answer useful please consider awarding points by marking the answer correct or helpful<!Session data>

I suggest to use diffent VLAN, and if possible, also different NIC for VMotion and iSCSI.
