its hard to explain the architecture on community forums but to give you some idea:
VMAX is divided in to 8 engines interconnected through MIBE (8 is the max engine count and 1 is minimum requirement).
Each engine contains 2 director boards with its own cache and processors.
Each director has 2 quad cores (in VMAX 20K). 4 core service the Host IOs (called Front end) and other 4 core service the disks (Called backend ports).
The memory on each director is shared with the memory of the other director (VMAX with single engine) or director of other engine(in case of more than 1 engine).
Each director has SIB modules that connects to the MIBE, A director communicate with other director through MIBE as if its directly connected, creates a virtual matrix of directors. thus the name VMAX.
