Multipathing Software
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
connected to the same dual-ported storage array.
For your server, three different types of multipathing software are available:
■ Solaris IP Network Multipathing software provides multipathing and
load-balancing capabilities for IP network interfaces.
■ VERITAS Volume Manager (VVM) software includes a feature called Dynamic
Multipathing (DMP), which provides disk multipathing as well as disk load
balancing to optimize I/O throughput.
■ Sun StorageTek™ Traffic Manager is an architecture fully integrated within the
Solaris OS (beginning with the Solaris 8 release) that enables I/O devices to be
accessed through multiple host controller interfaces from a single instance of the
I/O device.
For More Information on Multipathing Software
For instructions on how to configure and administer Solaris IP Network
Multipathing software, consult the IP Network Multipathing Administration Guide
provided with your specific Solaris release.
