Scalability limits for SMTape backup and restore sessions

While performing SMTape backup and restore operations through NDMP or CLI (tape seeding), you must be aware of the maximum number of SMTape backup and restore sessions that can be performed simultaneously on storage systems with different system memory capacities. This maximum number depends on the system memory of a storage system.

Note: SMTape backup and restore sessions scalability limits are different from NDMP session limits and dump session limits.
System memory of the storage system Total number of SMTape backup and restore sessions
Less than 16 GB 6
Greater than or equal to 16 GB but less than 24 GB 16
Greater than or equal to 24 GB 32

You can obtain the system memory of your storage system by using the sysconfig -a command (available through the nodeshell). For more information about using this command, see the man pages.
