But even at 255, the value of virtualization is still present. On Rick's point that you have to manage a z/VM guest just like any other node in the SAN fabric, well, there are no miracles. SMI-S provides a standard management API to make tool building easier. The good news is that NPIV allows a guest's SAN access to be managed exactly as a discrete server's would be, with no requirement to develop and System z-specific code.
