Master host storage requirements

The following table identifies the minimum local storage requirements of Control Center master host nodes in high-availability deployments.

Purpose Minimum size Description
1 Root (/) 2-10GB (required) Local, high-performance storage (XFS)
2 Swap 12-16GB (required) Local, high-performance storage
3 Docker temporary 10GB (required) Local, high-performance storage (XFS)
4 Control Center audit logging 10GB (configurable) Remote, XFS-compatible storage
5 Docker data 50GB (required) Local, high-performance storage
6 Control Center internal services data 50GB (required) Local, high-performance storage (XFS)
7 Application data 200GB (suggested) Local, high-performance storage
8 Application metadata 1GB (required) Local, high-performance storage (XFS)
9 Application data backups 150GB (suggested) Remote, XFS-compatible storage.

Areas 1-3 can be combined in a single filesystem when the operating system is installed. Areas 5-8 must be separate real or virtual devices. This guide includes procedures for preparing areas 5-8.

The suggested minimum sizes for application data (7) and application data backups (9) 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 space is 150% of the base size for data.

The suggested minimum size for application data backups is 150GB. For improved reliability and performance, Zenoss strongly recommends using shared remote storage or network-attached storage for application data backups. This guide does not include instructions for mounting remote storage, but does include a step for creating mount points.
