Support for HPE StoreOnce Catalyst Storage

Backup Gateway Support

HPE StoreOnce Catalyst libraries can be configured using Backup Gateways in the following 64-bit Operating systems.

  • AIX

  • HP-UX

  • Linux

  • Solaris

  • Windows

For a list of 64-bit operating system versions supported by these Backup Gateways, see Backup Gateway: System Requirements.

Supported HPE StoreOnce Software Versions

The following minimum software versions are supported for StoreOnce systems, including Catalyst and Cloud Bank stores:

  • StoreOnce Gen3 Systems: Version 3.18.7

  • StoreOnce Gen4 Systems: Version 4.2.3

  • StoreOnce Gen5 Systems: Version 5.1.0

  • HPE Data Protection Accelerator Node for X10000: Version 5.0.0

Feature Support

  • The HPE Catalyst Storage library supports all the operations available in a Disk Library.

Note

  • One mount path per library is supported.

  • Move mount path is not supported.

  • As the options for deduplication, data compression and data encryption are provided in the device, these options are not available in the Storage Policy Copy associated with a HPE Catalyst Storage library.

  • Data Immutability is supported for HPE StoreOnce Catalyst libraries.

  • High bandwidth mode is not supported for HPE StoreOnce Catalyst libraries.

  • Data multiplexing is not supported and should not be enabled.

  • Inline Copies and Parallel copies are not supported.

  • The following information on copies must be noted:

    • Auxiliary copy uses the Catalyst Copy feature to copy data between StoreOnce appliances.

    • Auxiliary copy to another StoreOnce, tape and/or disk media is supported.

    • Synthetic full backups across StoreOnce appliances is not supported as synthetic full backups uses the Catalyst Clone feature to copy data without reading data back to the Backup Gateway.

    • Auxiliary copy from StoreOnce primary copy to a secondary copy with disk or cloud storage results in data size larger than primary copy. Since compression is disabled on primary copy, backups to secondary copy are also written in uncompressed format.

  • Cloud Bank Storage is supported. The following information must be noted:

    • If a Cloud Bank Store is disconnected and later reattached, update the IP address to point to the new StoreOnce system.

    • When the Cloud Bank Store is attached to a StoreOnce system in read-only mode, configure the Backup Gateway connected to that StoreOnce as read-only.

    • In a multi-reader setup, two Backup Gateways are required:

      • one Backup Gateway with read/write access to the StoreOnce system
      • one Backup Gateway with read-only access to the StoreOnce Catalyst store
