Maximum NDMP sessions for Data ONTAP 8.x

Considerations when using NDMP

You have to take into account a list of considerations when starting the NDMP service on your

storage system.

• Data ONTAP supports a maximum of 16 concurrent backups, restores, or both on a local tape

drive.

This includes backups initiated by NDMP as well as by the storage system’s dump, restore, and

smtape commands.

However, a storage system supports a maximum of 32 dump or restore sessions and 32 smtape

sessions.

• NDMP supports a maximum of 128 concurrent sessions on NearStore and 40 on other systems.

The following table defines the maximum number of NDMP sessions for storage systems running Data ONTAP 8.x:

Platform	Max QSM/SV	Max QSM/SV	Max NDMP sessions	Max NDMP sessions
	(with NearStore)	(no NearStore)	(with NearStore)	(no NearStore)
