Dynamic Multi-Pathing (DMP)

Manages the I/O performance and path availability of the physical storage devices that are configured on the system.

DMP creates DMP metadevices across all of the paths to each LUN. DMP uses the DMP metadevices to manage path failover and I/O load balancing across the paths to the physical devices.

DMP metadevices provide the foundation for Veritas Volume Manager (VxVM) and Veritas File System (VxFS). DMP also supports native operating system volumes and file systems on DMP devices.

Veritas Volume Manager (VxVM)

Provides a logical storage abstraction layer or storage management between your operating system devices and your applications.

VxVM enables you to create logical devices called volumes on the physical disks and LUNs.The applications such as file systems or databases access the volumes as if the volumes were physical devices but without the physical limitations.

VxVM features enable you to configure, share, manage, and optimize storage I/O performance online without interrupting data availability. Additional VxVM features enhance fault tolerance and fast recovery from disk failure or storage array failure.

Veritas File System (VxFS)

Provides a high-performance journaling file system.

VxFS is designed for use in operating environments that deal with large amounts of data and that require high performance and continuous availability.

VxFS features provide quick-recovery for applications, scalable performance, continuous availability, increased I/O throughput, and increased structural integrity.

Replicator (VR)

Enables you to maintain a consistent copy of application data at one or more remote locations for disaster recovery.

Replicator provides the flexibility of block-based continuous replication with Volume Replicator (VVR) and file-based periodic replication with File Replicator (VFR). Replicator option is a separately-licensable feature of Storage Foundation.
