Mounting a Harmonic MediaGrid File System Using a Macintosh
Network Settings
Use interface chosen by system
—selected by default, this option uses the default NIC on your
Mac FSD client when connecting to the Harmonic MediaGrid system.
Use all available network interfaces
—select this option to use all available NICs on your Mac
FSD client when connecting to the Harmonic MediaGrid system.
Use specified network interfaces
—select this option if you wish to specify the NICs on your
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
—select this option if you wish to limit the total read bandwidth on
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
for more information.
Use case-insensitive file names
—select if you would like to set the file system to be case
insensitive. By default, the Harmonic MediaGrid file system is case sensitive.
Deny delete/rename of open files
—this option prevents the deleting or renaming of 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
—this option provides exclusive write access for
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
—select this option to improve the display time for large Harmonic
MediaGrid directories in NLE workflows.
Use high read priority
—selected by default, this option provides low latency for read
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.
