Scale limits for Workflows deployment

NSP supports up to 64 asynchronous tasks. When the limit is exceeded, additional tasks are queued and will get executed as any of the executing workflows completes.

NSP supports up to 15 synchronous workflows. Synchronous workflows consume more resources and must be limited in parallel executions.

The following table presents scaling dimensions of stored executions for deployment of the NSP's Workflows function.

NETCONF

Up to three concurrent channels per NE during discovery. (One RW with notifications/keep-alive, two RO with 10-min idle timeout.)

One channel during normal operation.

gNMI/gRPC

Two channels (one channel from MDM, one channel from CN-Telemetry).

CLI/SSH

One active during database backup or upgrade operations.

SFTP/SSH

One for accounting file transfers and one for NE load transfer.

Total number of configuration instances in Device Management

500 000

Note: Customers should use caution when invoking bulk actions at the template level with many thousands of configuration instances as this may take many hours to complete. Bulk operations will be optimized in a future NSP release.

Scale limits for intent type artifacts

NSP provides a wide variety of artifact bundles, some of which contain intent type artifacts. It is recommended that artifact bundles are installed selectively to ensure that no more than 200 intent type artifacts are deployed on a single NSP system.

If your NSP system requires more than 200 intent type artifacts, or if you have unknowingly exceeded 200 intent type artifacts and your pod won't come back up after a restart, please contact Nokia support.

Scale limits for SNMP adapters

The NSP SNMP adapter artifacts, which provide SNMP adaptation for standard SNMP devices, can manage up to 50,000 devices in a large-scale NSP deployment. Devices are discovered at /24 subnet (250NEs at once), however, multiple discovery rules can be initiated in sequence. For large deployments, the user should stagger the discovery rule execution to limit the impact on the system. SNMP adapters utilize the MDM framework to manage basic functions such as discovery, fault management, and port inventory.

Note: The above figures represent the discovery of 7705 SAR NEs with minimal configurations, and do not account for more complex configurations such as services.

 

Scale limits for REST tokens

The supported maximum rate for granting REST tokens is one token every 2.5 seconds.
