Multipathing Software Overview
Multipathing software enables you to define and control redundant physical paths to I/O
devices such as storage devices and network interfaces. If the active path to a device becomes
unavailable, the software can automatically switch to an alternate path to maintain availability.
This capability is known as automatic failover. To take advantage of multipathing capabilities,
you must configure the server with redundant hardware, such as redundant network interfaces
or two host bus adapters (HBAs) connected to the same dual-ported storage array.
For the servers, different types of multipathing software are available:
Oracle Solaris IP Network Multipathing software provides multipathing and load-balancing
■
capabilities for IP network interfaces. This software includes commands and other software
resources for server administration. For instructions on how to configure and administer
Oracle Solaris IP Network Multipathing, refer to Oracle Solaris Administration: Network
Services and Network Virtualization.
Oracle Solaris Multiplexed I/O (MPxIO) is an architecture fully integrated within the
■
Oracle Solaris OS that enables I/O devices to be accessed through multiple host controller
interfaces from a single instance of the I/O device. (Previously, this functionality was
called StorageTek Traffic Manager.) For information about MPxIO, refer to Oracle Solaris
Administration: SAN Configuration and Multipathing Guide.
