External Storage System
ESS supports generation of EDR/UDR/FDR (xDR) files from the chassis. To store generated xDR files, on the ASR
5000 chassis, the system allocates 512 MB of memory on the packet processing card‘s RAM. The generated xDRs are
stored in CSV format in the
/records directory on the packet processing card RAM. These generated xDRs can be used
for billing as well as for generation of reports to analyze network usage and subscriber trends. As this temporary storage
space (size configurable) reaches its limit, the system deletes older xDRs to make room for new xDRs. Setting gzip file
compression extends the storage capacity by approximately 10:1.
Because of the volatile nature of the memory, xDRs can be lost due to overwriting, deletion, or unforeseen events such
as power or network failure or unplanned chassis switchover. To avoid loosing charging and network analysis
information, configure the CDR subsystem in conjunction with the External Storage System (ESS) to offload the xDRs
for storage and analysis.
For more information on the ESS, refer to the ESS Installation and Administration Guide .
