Storage Utility High-Availability Configurations
Storage Provisioner supports two high-availability configurations: straight cable
and cross cable.
■
A straight-cable configuration consists of two storage systems, a host system,
a host path with two HBAs, and each path is connected to the same utility.
■
A cross cable configuration consists of two storage systems, a host system, a
host path with two HBAs, and each host may contain multiple paths (two
HBAs each) with each path connected to the same storage utility or another
utility.
In both configurations, each HBA sees each storage system within the utility.
High-availability configurations provide for improved performance and greater
availability of your storage systems. For more information about straight cable
and cross cable configurations, refer to the SAN Design Reference Guide at:
