Virtualization’s impact is substantial. In some cases, such as VMware’s ESX, it effects the server provisioning process because VMware ESX provides the drivers for various HBA’s and storage systems. From the switch perspective, it makes obtaining information about the number of paths a little different from what is done on other operating systems.
