CLI Storage-Management Guide 1-3

Resilient Overlay Network (RON)

You can connect multiple ARXes with a Resilient Overlay Network (RON), which

can reside on top of any IP network. This provides a network for distributing and

accessing file storage. ARXes can replicate storage to other switches in the same

RON, updating the replicas periodically as the writable master files change. This is

called a shadow copy, where a source volume on one switch periodically copies its

files to one or more shadow volumes on other switches. Clients can access the shadow

volumes at multiple geographic locations, independent to where the source volume

resides.

Audience for this Manual

This manual is intended for

• network technicians responsible for layer 1 and 2 networks,

• network engineers responsible for the Internet Protocol (IP) layer (layer 3),

• storage engineers who design and manage storage systems (SANs, NASes, and

DASes), and

• crypto officers who manage all of the Critical Security Parameters (CSPs) of a

network.

The text presumes that all readers are comfortable with a command-line interface

(CLI), especially one based on the Cisco IOS.

Using this Manual

The next chapter shows some of the problems in today’s storage networks and

provides high-level instructions for using the ARX to solve those problems.
