The single shared ring buffer is the default setup on all Allegro Network Multimeters that are shipped with '''one''' internal or external storage device. This is designed for using '''ONE''' internal, external or iSCSI storage device. ( Please see the section [[#iSCSI ring buffer]] for more information ). You can check at '''Generic''' → '''Storage''' if the Allegro Network Multimeter has detected a storage device. Here an example of ONE attached disk: | The single shared ring buffer is the default setup on all Allegro Network Multimeters that are shipped with '''one''' internal or external storage device.

Here you can decide whether disk encryption will be used or not, see [[#Encryption]] below. You can also decide if and how much space can be used for the '''packet ring buffer'''. Please note that you cannot save any pcap files to the external disk when you use '''100 %''' for the '''ring buffer'''. | Here you can decide whether disk encryption will be used or not, see [[#Encryption|Encryption]] below.

If the disk has been formatted, you can continue with the configuration of the '''ring buffer''' at '''Generic''' → '''ring buffer'''. If you have created a disk with a ring buffer, you should see the statistics of the buffer as in the screenshot here below. | If the disk has been formatted, you can continue with the configuration of the '''ring buffer''' at '''Generic''' → '''ring buffer'''.
