Fabrics with different speeds

Hello all helpful folks,

We are planning to build a SAN island at our shop and are trying to gather swiches from wherever we can. We cant buy a new one. We have one switch which has maximum speed of 2gbps and another switch at 4gbps.

i) Can we build two fabrics using these two switches, knowing that they will operate at different speeds?.

ii) What will be the impact to the host or the array if we do this?.

iii) What will be the impact to the host based load balancing, if any?

iv ) Should we force the speed of the 4gbps switch to 2gbps or does it not matter because they are independent fabrics?

Thanks a bunch!
