ESXi 4.0 / 4.1 Broadcom iSCSI setup / Support with iSCSI offloading

[mquast]

Hello.

I am new to iSCSI usage on ESXi so I may have some question already answered. Sorry for that.

Is it right that ESXi 4.1 supports iSCSI offloading while ESXi 4.0 does not?

How to set it up properly? I have a Dell R510 with a Quadport Broadcom NetXtreme II 5709.

I like to use two network ports from the 5709 with LACP link aggregation to connect to my iSCSI target (QNAP).

I have found some posts regarding creating two vSwitches which each one network card and mapping the vSwitch (vmkx) to the vmhbaXX (esxcli swiscsi nic add -n vmk1 -d vmhba35).

Is this the right way? How to configure the link aggregation then?

This is how it looks like:

Thanks,

Michael

You need to have both vmnics under the same vswitch.  The nic teaming options are at that level.

Hi.

Thank you for your answer. Yes, I needed to build one vSwitch instead of two. But I think that for iscsi it is better not use LACP. Use different ips for the Nics.

Thanks
