The storage systems are compatible with the Solaris Operating Environment Multi-path I/O (MPxIO) multi-pathing driver that offers hardware transparency and multi-pathing capabilities. MPxIO is fully integrated within the Solaris operating system (beginning with Solaris 8) and enables I/O devices to be accessed through multiple host controller interfaces from a single instance of the I/O device.
MPxIO enables you to more effectively to represent and manage devices that are accessible through multiple I/O controller interfaces within a single instance of the Solaris operating system. The MPxIO architecture:
- Helps protect against I/O outages due to I/O controller failures. Should one I/O controller fail, MPxIO automatically switches to an alternate controller.
- Increases I/O performance by load balancing across multiple I/O channels.
