Present day z/Arch machines are the combination of several POWER PC chips working together. With the inclusion of LPAR as the only mode to operate the machine, logically, the storage management is more than just the old storage keys, there are also additional KEYS to manage the LPARs themselves and PREVENT one LPAR from looking into the storage of another LPAR. The machine complex is a large emulator of the z/ARCH instruction set, memory/storage subsystem and IO processors. In other words, it's a very fast emulator.
With very little change, the hardware is zServer, iServer and pServer, all running different instruction set emulation, but sharing a lot of functionally, like LPAR support in all three. The expert on this would be Lynn Wheeler... so the rest I'll defer to the experts.
