Scalability limits for NDMP sessions

You must be aware of the maximum number of NDMP sessions that can be established simultaneously on storage systems of different system memory capacities. This maximum number depends on the system memory of a storage system.

The limits mentioned in the following table are for the NDMP server. The limits mentioned in the section “Scalability limits for dump backup and restore sessions” are for the dump and restore session.

System memory of a storage system Maximum number of NDMP sessions

Less than 16 GB


Greater than or equal to 16 GB but less than 24 GB


Greater than or equal to 24 GB


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.
