Network Operations
Each processor has its own memory, and each NonStop Blade Element (described in
the next section) has its own power supply; therefore, each processor can function
independently. However, each processor can also communicate with all the other
processors in the system, as well as with all input/output components, over the dual
ServerNet fabrics.
