Chapter 1 System Overview and Requirements
© 2017 Harmonic Inc. All rights reserved. 29 Harmonic MediaGrid Release 4.1
Required Information for a Windows Domain Controller
At this time, Harmonic supports connecting only one ContentStore 5840 to a ContentServer.
Required Information for a Windows Domain Controller
A domain controller server, which manages access to resources within a Windows domain, is
required at the installation site. Harmonic MediaGrid must be “joined” to the site’s Windows
domain for user authentication and security when clients attempt to access Harmonic MediaGrid
file systems.
NOTE: Instructions on how to configure a Windows Domain Controller are not included in this guide. The
domain controller should be set up before installing Harmonic MediaGrid.
The following information is required to join Harmonic MediaGrid to a Windows domain:
The type of Windows domain controller (Windows Server 2012, Windows Server 2008).
The name of the Windows domain controller.
The IP address and the name of the Windows Active Directory controller machine.
A domain administrator’s user name and password for the Windows Active Directory
controller.
The site’s Active Directory domain name. The Active Directory domain name must be a Fully
Qualified Domain Name (FQDN), which is a domain name containing three or four parts, (for
example, “ahost.example.com”).
The site’s Windows NT domain name. This may often be the first word of the Active Directory
domain name.
The IP address of the DNS (Domain Name System) server that contains entries for the
Windows Active Directory controller machine.
Required Information for Network Configuration
Harmonic MediaGrid is a network storage system, running its own DHCP server for management
of the subnets within the system. The ContentDirector that runs the DHCP server assigns IP
addresses to the ContentServers. A range of IP addresses must be reserved for integrating
Harmonic MediaGrid into the customer network.
NOTE: Instructions on how to design a network infrastructure are not included in this guide. The network
should be set up before installing Harmonic MediaGrid.
The following information is required for network configuration of the Harmonic MediaGrid
system. You will need this information when you run the configuration assistant to configure your
system:
The total number of each Harmonic MediaGrid device.
NOTE: The Harmonic MediaGrid configuration assistant asks for the maximum number of devices you
wish to allow for in your system. If you select a number that is too low for future expansion, you may be
forced to incur system down-time in order to reconfigure the system at a later time.
Cluster names and device names
For the Harmonic MediaGrid 3000 Series only: Type of network (1GbE or 10 GbE)
