Follow these steps to calculate load and the required number of processors:
1. Sum all base and fixed loading factors in the system.
• The system is considered a “lightly” loaded system if the system
wide sum of all base and fixed loading factors is less than 160.
Abase multiplier of 1.0 should be used in later calculations.
• The system is considered a “medium” loaded system if the system
wide sum of all base and fixed loading factors is greater than or
equal to 160 but is less than 320. A base multiplier of 1.5 should be
used in later calculations.
• The system is considered a “heavy” loaded system if the system
wide sum of all base and fixed loading factors is greater than or
equal to 320. A base multiplier of 2.0 should be used in later calcu-
lations.
2. Using the base multiplier that is specified above based upon the system
wide sum of the base and fixed loading factors, distribute the devices
throughout the system. Do not exceed 200 devices which is the
maximum load for the CM-4400 processors.
Note The base multiplier is based upon the sum of the device counts of all devices
system wide, NOT upon the devices on any single processor board. There-
fore, if the system widesum of the device count is 400, you must use a base
multiplier of 2.0 when configuring the system. You can not merely sum the
devices connected to each individual processor using a base multiplier of 1.0
and keep this sum under the specified maximum loading.
Example
A system is to contain the following:
• 2 channels of Saturn (1 DVP, 2 DAPs per channel). (Saturn Video and
Aud
io Processors do not directly contribute to Jupiter loading)
• 1 Saturn MCC 3500 Master Control Console with the Select panel used
for delegation purposes. (Saturn MCC 3500 panels do not directly con-
tribute to Jupiter loading unless the Select panel is used with a backup
switcher)
• 1 Saturn DVE (Sony serial machine protocol)
• Venus router control
• 1 Triton remote router control
•1 ASCII
• 1 ESswitch (high switch rate)
Since the sum of the base and fixed load factors of
all devices in the system
is greater than or equal to 320, this would be considered a heavily loaded
system. Therefore, the indicated Base Multiplier (BM) would be 2.
