Harmonic MediaGrid Components
ContentStore 5840 (84-drive 5RU server): At this time, a single ContentStore 5840 can
connect to the ContentServer 3000 or 4000. Refer to ContentStore 5840 and 5840A for
additional information about this server.
IMPORTANT: Harmonic MediaGrid 3000 series and 4000 series units cannot be combined in a single
stack.
ContentBridge
The ContentBridge is an optional server that provides access to Harmonic MediaGrid for client
platforms that do not have the File System Driver (FSD) installed or do not use the Harmonic
MediaGrid API. The ContentBridge also supports active files transfers. This server provides a
translation function for the following protocols:
CIFS (Common Internet File System)
FTP (File Transfer Protocol)
NFS (Network File System)
Refer to ContentBridge 2010F for additional information about this component. The 2010F is
available with copper CX4 or multi-mode fiber connectors.
SystemManager
The SystemManager platform is comprised of both hardware and software components that
communicate with the Harmonic MediaGrid network over Ethernet, providing software update
capability, network management, configuration, security and fault monitoring services.
Harmonic MediaGrid features that are enabled, modified, or part of the SystemManager
application are described in the SystemManager documentation. See the Harmonic
SystemManager User Guide for more information.
Harmonic MediaGrid ContentManager
A separate ContentManager application is also available from Harmonic. ContentManager is used
for setting, reviewing and changing attributes on associated files, directories, and user
permissions of Harmonic MediaGrid. Refer to the ContentManager User’s Guide for more
information.
Harmonic MediaGrid File System Driver Software
Harmonic MediaGrid file system driver software, installed on customer supplied desktops,
communicates with the system to store and retrieve files. See the Harmonic MediaGrid Release
Notes for your particular client platform for the latest supported client operating systems.
About Jumbo Frames Support
Jumbo frames are a feature that allows for larger transmission sizes of Ethernet frames over a
network. Harmonic MediaGrid supports jumbo frames; however, every device on your network
between Harmonic MediaGrid and the client (including the client itself) must also support jumbo
frames, with a common packet size, to take advantage of this feature. Network performance is
severely impaired otherwise.
