Chapter 1. Introduction to DX Content Router

1.1. Overview of DX Content Router

A DX Storage cluster routinely replicates content objects to other nodes in the same cluster in order
to improve fault tolerance and performance. For disaster recovery and other reasons, it may also be
desirable to automatically replicate content objects to another, remote cluster. The remote cluster
may typically have the following properties:
• A different multicast domain than the local cluster
• Connectivity to the local cluster via Transport Control Protocol (TCP)
• One or more firewalls separating it from the local cluster
• Unpredictable network latency that may prevent communication for long periods of time
The normal replication techniques used within a DX Storage cluster are not appropriate for remote
replication between clusters of this sort. DX Content Router (CR) supplies a more appropriate
mechanism for remote replication. It also supplies enumeration of DX Storage content for other
purposes like search indexing or virus scanning.

1.2. About this Document

1.2.1. Audience

This document is intended for people in the following roles.
1. Storage system administrators
2. Network administrators
3. Technical architects
4. Application integrators writing with the Enumeration API
Throughout this document, the storage system administrator and network administrator roles will be
referred to as the administrator. The administrators are normally responsible for allocating storage,
managing capacity, monitoring storage system health, replacing malfunctioning hardware, and
adding additional capacity when needed.
This document will be valuable to technical architects in designing scalable, highly redundant, cost
effective application storage solutions.

1.2.2. Scope

This document covers the steps needed to deploy DX Content Router and the administrative actions
necessary to monitor and run one or more DX Content Router nodes. The reader is expected to
have a background in TCP/IP networking, basic knowledge of server-class hardware, and optional
experience with regular expression languages.
