Question : Problem: redundant path san storage

We want to increase performance and redundancy with our VMWare & StoreVault SAN solution.  If we want to enable NIC teaming on the SAN for performance, what is the best way to built fault tolerance and still maintain highest throughput.   What I had in mind is the following.

Enable NIC teaming on the StoreVault
Connect each NIC on the SAN to a separate switch
connect each VMWare host HBA cards to both switches

This should be possible with LACP trunking?

Answer : Problem: redundant path san storage

yepp, totally correct.
you can have vlans on link aggregated cards/ports.
until you have both switches/nics funtioning your performance will be doubled.
still you have to bear in mind that in most cases network performance is not an issue, botlenecks often happen in disk subsystem.
