Host multipathing

Multipathing in VMware supports several paths.

VMware supports three types of multiple paths:

Fixed path
The I/O initiates access from the path that is initially selected, and switches to a different path if problems are encountered.
Most Recently Used Path
VMware uses the most recently used path, and switches to a different path if problems are encountered.
Round Robin
VMware accesses the different paths available at fixed intervals.

VMWare 4.0 enables native multipathing by default. In that configuration, only one disk drive is listed regardless of the number of paths that are available to it.
