iSCSI Teaming?

I haven't worked with iSCSI before (so I may be asking a dumb question),
but if the iSCSI is encapsulated within TCP, can one configure Teaming
on your dedicated NICs to enhance iSCSI throughput?

Also, are there any commands that can be used (with NetWare) to
enable/use a NIC's TCP/IP Offload Engine (TOE)? [We have two
onboard Broadcom Adapters that support TOE . . . normal network
communications are setup using a Dual port Intel NIC with its own
Teaming.]

Thanks,

-Steve

You can configure teaming, but it will not enhance your throughput. That
is neither limited by the NIC (if we're talking about gigabit of
course), nor does nic bonding or teaming increase the throughput of one
individual connection (which iSCSI is) at all. *If* nic teaming and
bonding ever increaes performance (which I highly question in 99% of all
setups), then if you have *many* connections. E.G, if a few thousand
users from a few thousand computers talk to your server simultaneusly.
