Le multipathing est un terme technique décrivant une tolérance de panne en multipliant les chemins d'accès aux disques SAN
The term multipathing is a fault-tolerance technique used to spread the disks over multiple
input/output (I/O) adapters. If you do not use multipathing, you will run into I/O path reliability
problems trying to communicating to the SAN. Multipathing takes advantage of multiple paths
between a host system and the storage subsystems (LUN) or set of LUNs, as shown in
Figure 1-1. When an adapter fails, the system automatically reroutes I/O operations to
another available path. This support also allows the balancing of the I/O load in multiple
paths, preventing I/O bottlenecks.
