I have a swtich stack comprised of three 3750G series swtiches. 1x 12sfp fiber port 10/1000 and 2x 24port 10/1000 ethernet switches in this stack.  I am setthing up a etherchannel connection comprised of 4 cables to a SAN device. I want to balance the bandwidth load for these 4 port connections across the two 24 port switches int his stack.  I am planning to plug two cables into 1/0/2 and 1/0/3 respectivly in this design.  My question is of total available bandwidth across the switch stack, does each port have true 10/1000 speed or is it distributed across a group of port ex. 1-4, 5-8 etc. in a peer relationship? Thus having an effect weather I etherchannel consecutive ports or the port in each group to balance the load back to my SAN.

All feedback appreciated!
