VMware NIC Teaming Issues

We have six Dell R610 ESXi 5.0 host that have the Broadcom NetExtreme II BCM 5709 network card. On all six of the host we have two ports teamed for LAN access and two ports teamed for SAN traffic.

The ports for the LAN access are working fine but the second port for SAN traffic is showing no traffic. Pictures attached that show the port having no traffic. We have tried to update the drivers at the ESXi level but everything we have tried has not fixed the issue.

We also noticed that whatever NIC is second on the list of activate adapters is the one with no traffic.

Any ideas would be much appreciated!

Do you have the latest NIC firmware from Dell installed as well as the latest BIOS?

Firstly, I would not team for iSCSI traffic, use single nics, and use multipath, teaming is not supported for iSCSI SAN traffic, multipath across single NICs. The Best Practice on how to do this is listed in my EE Articles

Teaming is fine for Virtual Machine Network, Management Network, but use Multipath for iSCSI Storage traffic as below

You do not state what SAN you have, you may also need to install the required software for your SANs, multipath modules.

We have two Promise VessRAID 1840i.

The drivers and BIOS are current.

We can setup the multipathing but we have set it up with teaming on HP servers and it works just fine so we were confused and why it wouldn't work on these Dells.

Whatever you recommend we will give it a try.

It's *never* recommended, on any OS, VMware ESXi or Microsoft Hyper-V.

MPIO! (multipath!).
