Using Storage Area Manager in a Dual-Redundant Fabric Configuration
Storage Management Appliances are often deployed in dual-redundant Fibre Channel
environments.
The Storage Area Manager software is compatible with dual redundancy.
Using dual-redundant Fibre Channel paths for storage management enables the SMA to have
redundant control over the SAN, creating an environment with no single point of failure. In
such a configuration, the SMA has two host bus adapters (HBAs), allowing greater ability to
provide nonstop management control and monitoring of critical SAN devices.
Figure 4 shows two fabrics with fiber connections between the SMA, a host, switches, and
storage devices, including:
■ The SMA with two host bus adapters
■ A storage host system on which you install the Storage Area Manager host agent software
■ An HSG controller pair connected to the fabric through Ports 1 and 2 (top controller) and
Ports 1 and 2 (bottom controller)
■ An HSV controller pair connected to the fabric through Fabric Ports 1 and 2 (top
controller) and Fabric Ports 1 and 2 (bottom controller)
