If using stackable switches (with 802.3ad support) is it possible to connect each of the 2 NIC to a different switch?  I am working on a project with a very limited budget (reason why I am using iSCSI rather than FC), can someone please suggest a few budget switches that support LACP and stacking? Excellent article Greg.

Greg, could you elaborate a bit mopre about this? You mean we can achieve using more than a aphysycal link capacity for a single connection? Thanks for the excellent article!!! “You can configure the Switch LACP AND the Server LACP (since each can

Port to make the full LACP bandwidth available to a single iSCSI
initiator / target pair.”

You might be interested to know that HP's E3500+ series switches support Distributed Trunking otherwise referred to as DT-LACP. I've just recently implemented it in combination with a NetAPP iSCSI based storage system and 2 x E3500 series switches and it appears to work quite well although I'm not completely convinced yet. Catalyst & StackWise+ anyday of the week + EtherChannel. Excellent article and interesting reading.
