Understanding and managing zone database size

The maximum size of a zone database is the upper limit for the defined configuration, and it is determined by the amount of memory available for storing the master copy of the defined configuration in flash memory.

Use the following information displayed by the show zoning operation-info command to determine whether there is enough space to complete outstanding transactions:

  • db-max — Theoretical maximum size of the zoning database kept in nonvolatile memory
  • db-avail — Theoretical amount of free space available
  • db-committed — The size of the defined configuration currently stored in nonvolatile memory
  • db-transaction — The amount of memory required to commit the current transaction

The supported maximum zone database size is 100 KB. If the outstanding transaction data (db-transaction field) is less than the remaining supported space (100 KB minus db-committed), enough space exists to commit the transaction.

The db-max field has a theoretical zone database limit of approximately 1 MB. However, performance might become unacceptable if the zoning database exceeds 150 KB.
