How Storage Devices, Storage Pools and Volumes work in ClusterLogics
Storage Devices (SD)
- These are the devices which store the backup data (WAN or LAN attached)
Storage Pools
- Storage pools are created on storage devices (see above)
- The are comprised of volumes and are resized up or down based on adding/removing a volume (see below)
- Customers can create pools and assign servers (FDs) to backup data to specific pools
- Customers can also create a pool per server (FD) they are backing up during the server (FD) install wizard process - THIS IS THE RECOMMENDED USAGE OF POOLS
- Pools can be moved between storage devices (SDs) to manage capacity
Volumes
- Volumes are the building blocks of storage pools
- Customers can set the size of their volumes when creating pools
- ClusterLogics recommends smaller volume sizes (ie 20 or 50GB volume sizes)
- Pool sizes are grown or shrunk by adding/removing volumes from the pool (ie a 200GB storage pool comprised of 4*50GB volumes, can be increased to 250GB by adding a 5th volume to the pool or to 150GB by removing a volume from the pool)
