Datastore Management

The Datastore in XLServer is powered by OpenZFS.
It provides a robust, scalable, and high-performance storage layer for snapshots, backups, and clones.

Initial Configuration​

  • During the initial configuration, the datastore is created with the disks you provide.
  • Mirroring rule:
    • If you provide an odd number of disks, the datastore is created without mirroring.
    • If you provide an even number of disks, the datastore is created with mirroring.
  • All datastore disks must have equal size.
  • To resize the datastore, you must provide an even number of disks of the same size if the datastore is mirrored.

You can also configure logs and cache during the initial setup.
If not, they can be added later via the Web Console.

Viewing Datastore Details​

Datastore management is done from:
System > Settings > Storage tab

From this tab, you can view details about the datastore:

  • If the datastore is mirrored or not (if mirrored, (mirrored) appears in the card header Datastore Details).
  • If quota is applied.
  • Total size, allocated space, and free size.
  • Deduplication ratio.
  • Fragmentation percentage.
  • Total number of snapshots stored.
