You have - 16 HiperSocket chpids available - 64 control units per chpid - 256 devices (subchannels) per control unit - Providing up to 12K devices, spread across 16 chpids or all in one. - Yielding up to 4096 NICs Are you sure you're up against a HiperSocket maximum? If you have 4096 NICs, consider using VLANs. Alan Altmark z/VM Development IBM Endicott
