duplicate scenario

Hi,

I havean infrastructurecurrently in production this way:

1.-Balancer hardware.
2.- 2 IIS Front Servers (aspx)
3.- 2 SQL BackEnd Servers in cluster.

The data of servers (IISandSQL) is in NetApp storage.

My question.

AsI cansimulate thisvirtualscenarioto make atest?, we mustkeep in mind thatI do not havethe balanceror thestorage.There any alternatives to simulatethese twosoftwarehardware?

Thanks
