Flash memory complex with a replication interface to replicate data to another flash memory complex of a data processing system

A data processing system, comprising:

• a plurality of central processing unit (CPU) subsystems, wherein each CPU subsystem includes a plurality of CPUs and a plurality of memory controllers, each memory controller corresponding to one of the CPUs;
• and
• a plurality of memory complexes, each memory complex being associated with one of the CPU subsystems, wherein each memory complex comprises
• a plurality of branches;
• a plurality of memory leaves to store data, wherein each of the branches is coupled to one or more of the memory leaves and to provide access to the data stored in the memory leaves, and
• a replication interface to automatically replicate data received from one of the CPU subsystems to another one of the memory complexes, wherein the received data is to be stored in one of the memory leaves;
• and
• an Ethernet switch fabric coupled to each of the memory controllers of the CPU subsystems and each of the branches of the memory complexes, wherein each branch of each memory complex that is associated with one of the CPU subsystems is connected to another branch of another memory complex that is associated with another CPU subsystem and can communicate with each other through the Ethernet switch fabric, and the data is replicated via the Ethernet switch fabric,
• wherein each of the branches provides access to data stored in local memory leaves by a remote CPU via a remote branch of the remote CPU over the Ethernet switch fabric, without having to invoke a local CPU.
