The limit on the number of concurrent replication operations depends on your system model. The system resources are shared between SnapMirror and SnapVault replication operations. Therefore, the limit for a particular type of replication is reduced if there are any other types of replication operations being performed concurrently.
A SnapMirror replication or a SnapVault backup consists of two replication operations: one operation on the source system and the other on the destination. Therefore, if a system is both a source and a destination, it uses two replication operations. For example, systemA is the source as well as the destination system in a SnapMirror or SnapVault relationship and the total number of replication operations available for that relationship is 100. Then, the total number of available replication operations, when the transfer is active, is 98.
Each value listed in the following two tables indicates the maximum number of concurrent replication operations allowed for a specific model, when using a single type of replication. The values are exclusive, and not cumulative. For example, if you are using the maximum number of synchronous SnapMirror replication operations for a system as a source, you cannot use any more replication operations of any type for the system.

Therefore, a system with the NearStore personality can handle more replication operations than a system without the NearStore personality.
