Configuring the Number of OST Replication Streams

Configuring the Number of OST Replication
Streams
There are two types of replication streams used on the DXi6900 G2 system. Traditional Replication and
OST Replication. Traditional replication is used for replicating data between two DXi systems. OST
Replication is dedicated to NetBackup OST replication.
The default number of Traditional Replication streams is 8 and the number of OST Replication streams
is 2. If you want to increase the number of OST Replication streams, you must decrease the number of
Traditional Replication streams on the source system (see
Table 1: Maximum Traditional and OST Replication Streams
Maximum Number of Traditional Replication Streams
Caution: If the maximum number of OST Replication streams is increased on the source without a
corresponding decrease in the number of Traditional Replication streams, replications and other
operations will begin to fail because the maximum number of blockpool connections will be exceeded.
Both of the number of Traditional Replication streams and the number of OST Replication streams are
controlled by configurable variables.
Note: To change the number of traditional and OST replication streams, a reboot of the target system
is necessary.
