BLACK BOX® CS Installation, Administration, and User’s Guide 99
Note: Make sure that enough disk space is available to store the files in the location
you select. Sequentially-written files can quickly grow to exceed the storage
capacity of the local flash memory or remote hard drive. Data buffering
should only be done if processes are in place to monitor the stored data.
The following table shows the differences between remote and local data
buffering.
File Size (Bytes)
For Local Destination - Sets the value for this field to be
greater than zero.
Record the timestamp...
If enabled, the system inserts a timestamp in the buffer.
NFS File Path
For Remote Destination - Includes the path where the data
buffer file should be stored.
Show Menu
Defines the options you want to show in the menu of the
buffer file.

Option Description
Remote
server
Data is stored in files sequentially. The NFS server must be configured
with the mount point shared (exported). In linear mode, data is written into
a continuous sequence of files, and the file spaces is not reused. The
administrator needs to allow enough space for the expected amount of
data, and take measures such as moving unneeded data files off line, to
ensure data does not outgrow the available space.
Local files
Set a file size greater than zero. Make sure the file size does not exceed the
space available on the CS’s flash memory. If needed, you can supplement
the flash memory module by installing a flash memory card (with an
adapter) or other storage device in a PCMCIA slot. For a list of supported
PCMCIA cards see Appendix C.
