About MSDP Scaleout
MSDP Scaleout is based on MSDP. It empowers MSDP with high resilience and scalability capabilities to simplify management and reduce total cost of ownership.
It runs on multiple nodes to represent a single storage pool for NetBackup and other Veritas products to use. You can seamlessly scale out and scale up a MSDP Scaleout on demand. MSDP Scaleout automatically does failure detection and repair in the background.
It is deployed separately in NetBackup environment. The deployment process is with minimal user intervention. The core MSDP services run on each node to expose the storage optimized services, and manage a part of the cluster level data and metadata. Each MSDP Scaleout node is called MSDP engine.
