Four key features of z/Architecture include:
- It is a full 64-bit architecture that provides for 24, 31 and 64-bit coexistence.
- Intelligent Resource Director—Provides for an exclusive way to intelligently direct the processor and I/O resources to priority workloads running within the set of clustered LPARs.
- HiperSockets—A statement of direction for z/Architecture that permits a TCP/IP network to be established between LPARs.
- License Manager Enablement—The z/Architecture includes capabilities that enable IBM's License Manager to run on z/OS and z900. This capability, when combined with HiperSockets, creates an ‘n-tier’ environment for e-business applications within a z900.
