Live partitioning requirements, additional NSP components

Live auxiliary database partitioning scheme

The following table lists the partitions required for the live 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, 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.

Disks required: two 300 GByte (RAID 1), plus data storage and database backup storage capacity described in table		Size (GBytes)
Partition	Content	Single-station	Multi-station
swap	Swap space	16
/	Root	26
/home	User home directories	0.5
/opt	NSP auxiliary database software	100
/tmp	Temporary files	4
/var	System data	64
/var/log	System logs	6
/var/log/audit	System audit logs	6
/extra	NSP and NFM-P software storage	50
Data storage disks required, RAID 1+0:		Four 1.2-TByte	Twelve 600 GByte
/opt/nsp/nfmp/auxdb/data	Auxiliary database data	2200	3300
Database backup storage disks required, RAID 5:		Four 1.2-TByte	Five 1.2-TByte
/opt/nsp/nfmp/auxdb/backup 1	Auxiliary database backup data	3300	4400

Notes:

1. Auxiliary database backups are optional but strongly recommended to protect against complete data loss due to disk failure, data corruption, or upgrade failure. The backups can be stored on a separate volume, as indicated in the table above, or on a remote mount point reachable over a minimum 10 GByte/s link. The listed capacity is sufficient for at least one persisted backup.
