DMP (dynamic multipathing)

An input/output (I/O) enhancement technique that balances I/O across many available paths from the computer to the storage device to improve performance and availability.

A feature of Veritas Volume Manager that provides greater reliability and better performance by using path failover and load balancing for multiported disk arrays connected to host systems through multiple paths. DMP detects the various paths to a disk using a mechanism that is specific to each supported array type. DMP can also differentiate between different enclosures of a supported array type that are connected to the same host system.

DMP detects the various paths to a disk using a mechanism that is specific to each supported array type. DMP can also differentiate between different enclosures of a supported array type that are connected to the same host system.

An enhancement technique that provides the load balancing and path failover to disks that are connected to the Scalable File Server cluster nodes.

The Veritas Volume Manager Dynamic Multipathing facility.

A Veritas Volume Manager feature that allows the use of multiple paths to the same storage device for load balancing and redundancy.

A component of VxVM that supports path failover and load balancing for multiported disk arrays.
