What is the DPU memory allotment in a 7910A and a Non-mipped 7920?
Resolution
The red circle denotes shared memory slots for Messages and Cached Users.
- Messages take up 12 bytes of memory per message (Alarms & Transactions).
- Cached Users take up 16 bytes of memory per person.
All of sums of the messages and Cached Users are deducted from the 56,700 Bytes of memory.
Here is an example Tenant Editor:
If the number of individuals is set to 24,000, but only ~1000 actual people are in the system this situation can occur:
(From the Graphic on the first page “Resident User = 1 Byte”)
56,700 bytes of shared memory -24,000 (24,000 X 1 byte) __________ 32,700 bytes remain
The 32,700 bytes remaining in the DPU are for the SHARED memory to be used for Messages or Cached Users (DPU Resident) people. Increase the amount of SHARED memory by reducing the amount of Individuals in the Tenant editor from 24,000 to a more realistic amount.
