InstallationDX Content Router installs as a service on a standard server, using standard Linux installationand package management utilities as outlined in the sections below. Note, that if running DXContent Router from a Cluster Services Node (CSN), the required infrastructure setup, installationand configuration are performed automatically as part of CSN configuration so the steps beloware not necessary or even supported in some cases. Please reference the CSN Installation andConfiguration Guide for information on installing and configuring DX Content Router on the CSN.4.1. Requirements4.1.1. Operating SystemDX Content Router has been developed and tested with 64-bit Red Hat Enterprise Linux (RHEL)version 5.5. Other RHEL versions or Linux distributions are not currently supported. Subsequentinstallation instructions will assume an existing RHEL installation.4.1.2. 3rd Party Package Pre-requisitesDX Content Router has dependencies on Python 2.5, Python Setuptools 0.6c9, and Twisted 8.2.0,which are not available as standard RPM packages under RHEL 5.5 but are included in the DXContent Router installation package and will be unzipped into the same location as the DX ContentRouter rpm (see the 'Installing Services' section below). If installing on a Cluster Services Node(CSN), these RPMs will already be installed. If installing without a CSN, you may need to manuallyinstall the packages using the commands shown below (in this order):rpm -ivh caringo-3rdparty-Python-2.5.4-x86_64.rpmrpm -ivh caringo-3rdparty-setuptools-0.6c9-x86_64.rpmrpm -ivh caringo-3rdparty-Twisted-8.2.0-x86_64.rpm4.1.3. NetworkThe DX Storage system has been designed to work within standard TCP/IP networkingenvironments. This is achieved through the use of widely supported network services and protocols.4.1.3.1. Required CommunicationsA DX Content Router node must be able to initiate TCP connections with all nodes in a DX Storagecluster through the designated access port. This is typically HTTP port 80, but it is configurable bythe administrator.Internally, DX Content Router nodes must be able to communicate with each DX Storage nodevia UDP on port 7000 and through IP multicasting. The multicast address must be unique for eachcluster and is configurable by the administrator. Multicast communication is only necessary betweenthe DX Content Router nodes and the DX Storage nodes.All nodes in the DX Storage cluster, including DX Content Router nodes must reside within thesame IP subnet.4.1.3.2. Bandwidth RequirementsThe expected transfer rate for two clusters communicating over a wide area network can be roughlycalculated by dividing the minimum effective bandwidth available (ex: 512 kbps) by the numberof volumes in the target cluster. By default, DX Storage requires a minimum transfer rate of 1000bytes/sec before timing out connections. The transfer rate is not checked for the initial 20 minutes toprovide some latitude for network variability. Administrators anticipating a transfer rate below 1000
