Abstract

The traditional marketing strategy for main frame machines is to sell a customer a machine with power matching their initial requirement (i.e., a uni-processor). As the customer processing power grows, additional processors can be purchased by the customer and hot plugged into the existing system without machine operation interruption. Throughout the year, this approach has proved to gain tremendous acceptance from customers.

Automatic Upgrade of Customer OP System

      The traditional marketing strategy for main frame machines is
to sell a customer a machine with power matching their initial
requirement (i.e., a uni-processor).  As the customer processing
power grows, additional processors can be purchased by the customer
and hot plugged into the existing system without machine operation
interruption.  Throughout the year, this approach has proved to gain
tremendous acceptance from customers.

      For some main frame machines such as the one with low
temperature CMOS device, it is extremely difficult to perform machine
upgrading without the interruption of the operation of the machine,
if the traditional uni-processors pluggable approach is used.

      A new marketing strategy has been advanced to resolve this
dilemma.  The new strategy involved selling a customer with a MP
(i.e., 8 processors) but only a portion of the processors (i.e., 8
processors) are enabled according to the sell agreement.  As the
customer processing requirement grows, the machine can then be
upgraded by enable the other disable processors already inside the MP
by plugging on 'key' module.

      The purpose of this disclosure is to describe a method to
disable and enable the processor with the 'key' module.  The most
significance of this scheme is that first, it will hardly degrade the
processor performance and second, it will require a minimum amount of
hardware for the function of disable and enable the processor.  In
this disclosure, a safe guard scheme is also proposed to further
prevent the customer from the unauthorized use of the additional
processor in the MP.

      The novel scheme as shown in the figure, is described as
follows:  The SCE (system...
