Cisco ASR 5000 Series Product Overview ▄
When using the hard disk for EDR/UDR storage, EDR/UDR files are transferred from RAMFS on the PSC card to the
hard disk on the SMC card. The hard disk may also be used to store any data that needs to be backed up.
The secondary SMC card also contains a hard disk which serves as a redundant, and becomes active during an SMC
failover. The hard disk on the secondary is mirrored to the hard disk on the primary in order to avoid any data loss.
Basically, the drives are raid-1 redundant.
