[AusNOG] Cheapest half decent 10Gbps switch (for iSCSI only)

[Robert Hudson]

In a word, no.

Unless you have Enterprise Plus (which is the wallet-emptying version of
vSphere), then there's no support for aggregation/bonding, particularly for
iSCSI.

The best thing to do is set up a number virtual port groups with one active
physical NIC each (the other pNICs on the vSwitch must be disabled entirely
in the port group), assign an IP to each of them (you create them as a
vKernel port group, not a Virtual machine port group, and then bind each of
them to the software iSCSI adapter.  This gives you good multipathing -
most storage vendors then support round-robin as the method of
load-balancing across the ports.
