And if I was to use let's say 4 teamed ports coming out of the
storage server, and 2 teamed ports going into the xen node, would the max
I'd get be still 1Gbit?

and 802.3AD are used together on those HP Soho switches. I might be wrong but
LACP I think allows automatic negotiation to some degree at the switch side.
have used LACP with Broadcom based NICs in Windows and the HP switch you are
looking at. You only need to enable LACP on the switch ports plugged into your
disk box and then the software on the server should be able to sort the rest (I
enabled it with Broadcom NICs under Windows and it worked as

configuration and is designed to deliver highest performance with for example
automatically load balancing over several NICs. If you want to use vblade
you might be better off using bonding because vblade cannot handle several
interfaces in one instance. You'll get another performance penalty when using
several instances of vblade listening on different interfaces. I am not
sure if LACP enhances performance in your case: I think from one server to
the other you will only get 1GBit; for LACP to work as expected you need
many-to-many or many-to-one connections. All pakets belonging to a connection
will use the same wire. This article has some details: http://serverfault.com/questions/8512/multiplexed-1-gbps-ethernet also
Wikipedia has some information on this.
Another thing is that you loose
the ability of having a redundancy in the switching backend.
