Chapter 1. Introduction to the DX Object Storage Cluster

Services Node

1.1. DX Object Storage Cluster Services Node Overview

The DX Storage Cluster Services Node (CSN) is an integrated services node that centralizes

installation and configuration of both the network services required to run a DX Storage cluster and

the software used to interface with it.

1.2. Components

The DX Storage CSN infrastructure is made up of the following components:

1. A collection of required network services configured to support a DX Storage cluster, including

DHCP, PXE network boot, TFTP, syslog, NTP and several others

2. An integrated PXE network boot and configuration server for DX Storage nodes booted onto the

DX Storage CSN's internal network

3. Several SNMP MIBs with operational and status information for all nodes in the associated DX

Storage cluster as well as the DX Content Router Publisher and Replicator services

4. Integrated installation and configuration of DX Content Router and the SCSP Proxy

5. An administrative web console that provides easy configuration of common settings and

parameters as well as access to useful utilities like updating DX Storage software versions and

backup and restore of configuration files
