The IBM System z9 Mainframe facilitates the maximum utilization of its various resources through the use of Virtualization technology, which simulates the multiple instances of I/O resources as well as processors on a single machine. It provides a logical view instead of a physical view of data, computing power and storage capabilities of the System z9 Mainframe, which allows for better sharing of infrastructure with improved access to information as well as restriction of infrastructure sprawl and the security risks which are associated with it. One of the important implementation of virtualization feature in System z9 is N_Port ID virtualization. It is based on an extension of the Fiber Channel standards which permits the host bus adapter to perform multiple logins to the SAN fabric via a single physical port. This feature can be used to permit shared access simultaneously to the same SAN device (Bitner & Wade, 2008).
