Permit information
Permits are calculated based on available resources and allocated resources for a stream. The following are some available permits:
Each SpanFS physical node, including C5K, C6K and C8K, has 24 permits.
VMRobo has 12 permits.
Each VM edition node has 9 permits.
For any backup or recovery job, when a permit is granted, the SpanFS cluster returns a virtual IP from its available resources to the NetBackup job. This virtual IP, which represents a specific node in the cluster at that moment, is used by the NetBackup job to read from or write data to the cluster, depending on the operation.
