Step 5: Data Buffering [Wizard]
You can perform advanced configuration in Expert mode including the option
of setting up data buffering differently for individual ports or groups of ports.
T To Configure Data Buffering [Wizard]
1. In Wizard mode, go to “Step 5: Data Buffering.”
2. Click the “Enable Data Buffering” checkbox.
The “Destination” pull-down menu appears.
3. Select the location for the data files from the “Destination” pull-down
menu (either “Local” or “Remote”).
Additional pull-down menus and fields appear, depending on which
destination is selected.
4. When the destination is local, perform the following steps.
a. From the “Mode” pull-down menu, select “Circular” or “Linear” data
buffering.
b. Type a file size in bytes into the “File Size (Bytes)” field.
The file size cannot be zero.
5. When the destination is remote, perform the following steps.
Local files
Set a file size greater than zero. Make sure the file size does not exceed the
space available on the OnSite’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; see
“PCMCIA Card Slots” on page 13 for the supported PCMCIA cards.
Local data buffering stores data in circular or linear mode. In circular
mode, data is written into the specified local data file until the upper limit
on the file size is reached; then the data is overwritten starting from the top
of the file as additional data comes in. Circular buffering requires the
administrator to set up processes to scrutinize the data during the time
window before the data is overwritten by new data.
