Storage pool types
To help you determine which storage pool type best meets your storage requirements, you should evaluate the characteristics of each storage pool type.
Use the following table to evaluate each type of storage pool.
| Storage pool type | Description |
|---|---|
| Directory-container storage pool | A primary storage pool that a server uses to store data. Data that is stored in directory-container storage pools uses both inline data deduplication and client-side data deduplication. |
| Cloud-container storage pool | A primary storage pool that a server uses to store data. Use cloud-container storage pools to store data to an object-store based cloud storage provider. Data that is stored in cloud-container storage pools uses both inline data deduplication and client-side data deduplication. |
| Random-access storage pool | A set of volumes that the server uses to store backup versions of files, files that are archive copies, and files that are migrated from client nodes. Files are stored on DISK devices. |
| Sequential-access storage pool | A set of volumes that the server uses to store backup versions of files, files that are archive copies, and files that are migrated from client nodes. Files are stored on tape or FILE devices. Data that is stored in sequential-access storage pools uses both postprocess and client-side data deduplication. |
Use the following table to compare storage pool capabilities and choose the storage pool that most suits your business needs based on your storage requirements.
