Trial partitioning requirements, additional NSP components

Trial auxiliary database partitioning scheme

The following table lists the partitions required for the trial deployment of an auxiliary database.

For a multi-station auxiliary database, or a single-station database that has a high data rate, the /opt/nsp/nfmp/auxdb/backup partition has the following special requirements:

  • It is strongly recommended that the partition is a remote mount point or directly attached storage connected by a minimum 10 GByte/s link.

  • Each auxiliary database station requires a separate backup volume that is mounted as /opt/nsp/nfmp/auxdb/backup on the auxiliary database station.

    For example, if the specified auxiliary database backup location is /opt/nsp/nfmp/auxdb/backup, the auxiliary database stations require the following mount points:
    • station 1:

      remote_host:station_1_backup_volume_path/opt/nsp/nfmp/auxdb/backup

    • station 2:

      remote_host:station_2_backup_volume_path/opt/nsp/nfmp/auxdb/backup

    • station 3:

      remote_host:station_3_backup_volume_path/opt/nsp/nfmp/auxdb/backup

  • The supported file systems for the backup location are ext3, ext4, Ceph, and NFS.

Note: The /opt/nsp/nfmp/auxdb/backup partition can be a local mount point in a single-station database that has a low to moderate data rate.
