Veritas Storage Foundation (SF) = Veritas Volume Manager (VxVM), Veritas File System (VxFS), and Dynamic Multi-Pathing (DMP)

Infoscale products include all features of SF plus VCS

Components

is a storage management subsystem that enables you to manage physical disks and logical unit numbers (LUNs) as logical devices called volumes

is an extent-based, intent logging file system

Connects multiple, independent systems into a management framework for increased availability. Each system, or node, runs its own operating system and cooperates at the software level to form a cluster. VCS links commodity hardware with intelligent software to provide application failover and control. When a node or a monitored application fails, other nodes can take predefined actions to take over and bring up services elsewhere in the cluster

Provides multi-pathing functionality for the storage devices configured on the system. The product creates DMP metadevices (also known as DMP nodes) to represent all the device paths to the same physical LUN

Veritas Replicator enables cost-effective replication of data over IP networks for disaster recovery, giving organizations an extremely flexible, storage hardware independent alternative to traditional array-based replication architectures
