Description |
|
Dynamic Multi-Pathing (DMP)
|
Manages the I/O performance and path availability of the physical devices that are configured on the system.
DMP creates DMP metadevices for all of the paths to each LUN. DMP uses the DMP metadevices to manage path failover and 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 layer 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.
|
|
Volume Replicator (VVR)
|
Enables you to maintain a
consistent copy of application data at one or more remote locations.
VVR replicates data to remote locations over any standard
IP network to provide continuous data availability. VVR can replicate existing VxVM configurations, and can be
transparently configured while the application is active. VVR option is a separately-licensable feature of Symantec Storage Foundation.
|
|
I/O fencing
|
Protects the data on shared disks
when nodes
in a cluster detect a change in the network cluster
membership with a potential split brain condition.

A related product, Veritas Operations Manager, provides a centralized management console that you can use with Symantec Storage Foundation and High Availability products.
