About the support for Linux native multipath in BMR
In the data storage domain, multipathing is the ability of a server to communicate with its mass storage devices using more than one physical path; through the buses, controllers, switches, and bridge devices connecting them. Multipathing protects against the failure of paths but not from the failure of a specific storage device. Another advantage of using multipath connectivity is the increased throughput by way of load balancing. NetBackup BMR 7.5 and earlier versions supported EMC Powerpath solution. However to cater the demand for native multipath which is a platform-independent technique, NetBackup BMR has introduced support for native multipath for BMR versions 7.5 and later for the Linux platform.
Once the System Administrator has configured the Linux native multipath on the client systems, no additional installation, un-installation, or configuration steps are required from the BMR side to enable the native multipath. The native multipathing ability is already integrated with BMR 7.5.
