Chapter 6 Accessing the Harmonic MediaGrid
Network Settings
Use interface chosen by system

Mac FSD client when connecting to the Harmonic MediaGrid system.
Use all available network interfaces

FSD client when connecting to the Harmonic MediaGrid system.
Use specified network interfaces

Mac FSD client that will be used to connect to the Harmonic MediaGrid system. Enter each
NIC name (for example, "en0"), separated by a colon, in the field provided.
Global Options
Limit read bandwidth to

your Mac FSD client. Type the number of Megabytes per second (MB/s) you wish to specify
as the limit. Note that this setting applies to all Harmonic MediaGrid mounts from this Mac
FSD client.
IMPORTANT: The "limit read bandwidth" setting applies to all mounts on the Mac FSD client, including
any existing mounts, user-level as well as system-level mounts.
Connection Options
Read ahead—the amount of data to be pre-fetched for each open/active file. For most

applications, a ReadAhead value of 2 (default value) is recommended. Refer to
Memory Usage by the File System Driver
Use case-insensitive file names

insensitive. By default, the Harmonic MediaGrid file system is case sensitive.
Deny delete/rename of open files

which are in active use (in the application "open" state) by this client. Note that this setting is
only effective when it is applied to all clients accessing the Harmonic MediaGrid system.
Open files with exclusive write access

applications on the client. This means files cannot be opened for writing on another client
system at the same time. They can, however, be opened on other clients in read mode. By
default, this option is turned off.
Slow attribute refreshing

MediaGrid directories in NLE workflows.
Use high read priority

operations on the Harmonic MediaGrid file system.
About Importing and Exporting Mount Options
To be able to share these settings with other FSD clients, Mac FSD 3.5 and later allows you to
export and import the FSD settings.
IMPORTANT: Do not edit the exported file, as it will cause a later import operation to fail.
NOTE: If you have specified which network interfaces the client should use for communication with the
Harmonic MediaGrid, you may need to update the NIC names after importing settings on a different FSD
client, as NIC names may vary across client systems.
