Configuring the Number of OST Replication Streams
There are two types of replication streams used on the DXi6902 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 8 )
Table 8 Maximum Traditional
and OST 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.
