About FlashFS and ISFS
Flash memory is used on the System to store a permanent copy of an image and any
configuration data. This data is stored in a non-volatile partitioned filing system known as
FlashFS. SDRAM is used on the System to store a temporary copy of some of the files that are
stored in FlashFS. This data is stored in a volatile filing system known as ISFS.
ISFS stores a copy of FlashFS files to make them accessible to application processes for
storing of configuration data that can subsequently be written back to FlashFS.
For example, setting the IP address of the System and the ARP server it uses is the type of
information that would be configured during a session and then saved for future use as
configuration data in FlashFS.
