Hard Disk Support on SMC Card in ST40 Platform
To add storage capability a hard disk drive (HDD) has been introduced in the ST40
platform.
platform.
When storing CDR files on the SMC HDD, at first they are stored on the RAMFS before
being moved to the HDD. The files can then be off-loaded via FTP or SFTP to an external
server (such as the L-ESS or the GSS) or billing system.

When using the HDD for EDR/UDR storage, EDR/UDR files are transferred from RAMFS
on the PSC card to the HDD on the SMC card. The HDD may also be used to store any data
that needs to be backed up.

The secondary SMC card also contains an HDD, which serves as a redundant and becomes
active during an SMC failover. The HDD on the secondary is mirrored to the HDD on the
primary in order to avoid any data loss. Basically, the drives are raid-1 redundant.

primary in order to avoid any data loss. Basically, the drives are raid-1 redundant.
HDD support is only available on the ST40 platform, so in the case of an “ST16” or an
“ST40 without a HDD”, a card failover results in a loss of CDR files. In the case of card
failover on an “ST40 with a HDD”, the new Active SMC starts pushing the files. Any files
that are left in the middle of the transfer will be transferred again.

“monitor protocol” CLI Command Option to use with HDD Configuration
If the hard disk drive (HDD) is used for CDR storage, with the
monitor protocol
CLI
command in the Exec Mode, the CDR option (29) must be used and not GTPP option (27).
Link Aggregation
Provides a means of aggregating or trunking from one to four ports on a redundant pair of
Quad Gig-E line cards (QGLC) in order to guarantee a file transmission is sent serially over
one link until it is finished downloading. Each PSC and its associated QGLC(s) forms a
system and negotiates with an aggregation on a remote port using Link Aggregation
Configuration Protocol (LACP).
