Best practices: Avoiding media server resource bottlenecks with MSDPLB+ prefix policy
Beginning in NetBackup 10.1, a new feature to address the media/storage server bottleneck is available for NetBackup servers configured with scale-out NetBackup, such as NBFS (NetBackup Flex Scale) or Veritas Cloud Scale Technology. While Very Large Database (VLDB) supports only Oracle database backups, the MSDPLB+ feature works for all policies. It can help balance workloads (Oracle, MS-SQL, and so on) across the available cluster nodes. The MSDPLB+ feature can be enabled by adding the prefix MSDPLB+ to the policy name.
Performance of both features have been optimized in the release of NetBackup 10.1.1 with the Global Deduplication feature implementation. Based on internal Oracle workload testing and analysis, in some configuration, MSDPLB+ can outperform VLDB. Veritas recommends using MSDPLB+, if available, to ensure balanced workload distribution across the cluster nodes.
