I also am spanned over two switches.  You can use bonding, you just can't use 802.3 mode. 

I have MGMT bonded to two gig switches and storage bonded to two 10g switches for Gluster. Each switch has its own fw/router in HA. So we can lose either switch, either router, or any single interface or cable without interruption.

I can't use bonding, spanned over two switches.
Maybe there is another way to do it, but I am burned out, anybody with
an idea?

The server has 4x 10Gbps nics. I need up to 20Gbps throughput in HA mode.


Thanks.
