Recommended storage layout

The tests of available block storage are based on best practice recommendations for master hosts and delegate or collector hosts. Enter the following command to display information about available block storage:
lsblk -ap --output=NAME,SIZE,TYPE,FSTYPE,MOUNTPOINT
The suggested minimum sizes for application data and application data backups should be replaced with sizes that meet your application requirements. To calculate the appropriate sizes for these storage areas, use the following guidelines:
  • Application data storage includes space for both data and snapshots. The default base size for data is 100GB, and the recommended space for snapshots is 100% of the base size. Adding the two yields the suggested minimum size of 200GB.
  • For application data backups, the recommended minimum space is 150% of the base size for data.

Control Center master host storage

A Control Center master host should have a total of 7 separate block storage devices or partitions. The following table identifies the purpose and recommended minimum size of each.

Purpose Minimum size
1 Root (/) 30GB
2 Swap 16GB
3 Temporary (/tmp) 16GB
4 Docker data 50GB
5 Control Center internal services data (/opt/serviced/var/isvcs) 50GB
6 Application data 200GB
7 Application data backups (/opt/serviced/var/backups) 150GB

Control Center delegate host storage

A Control Center delegate or collector host should have a total of 4 separate block storage devices or partitions. The following table identifies the purpose and recommended minimum size of each.

Purpose Minimum size
1 Root (/) 30GB
2 Swap 16GB
3 Temporary (/tmp) 16GB
4 Docker data 50GB
