Question
Scenario:
The consultant is reviewing a customer's storage and backup infrastructure design for a possible upgrade new solution design. The existing environment consists of several HP DL servers connected to HP 24 SAN Switches. An HP Enterprise Virtual Array 4400 is used as storage for their virtualized servers. Some HP D2700 Storage Systems are direct connected to their Windows servers. An HP StoreOnce D2D 4106fc Backup System is used as primary backup target. Once a week backup data copied to an HP MSL4048 as secondary backup target using HP Data Protector (DP) 6.1, During the planning phase the consultant has to propose whether the existing solution can be upgraded or a new solution design is required. Refer to the scenario:
Upgrading the backup application and the primary backup system to the latest software version would provide which advantage?
Options
- AFederated Deduplication can be implemented using HP StoreOnce Catalyst.
- BA Media Agent can be installed on the HPStoreOnce Backup System using the HP DPStoreOnce client.
- CTape offload can be performed using direct-attached tape drives and the Data Protector echo copy functionality.
- DThe new HP Data Protector VTL license model can be applied.

Why each option
HP StoreOnce Catalyst enables federated deduplication across multiple backup devices, making it the correct upgrade path when replacing both the backup application and the primary backup target. This capability requires upgrading HP Data Protector to a version that supports the Catalyst protocol.
HP StoreOnce Catalyst is a protocol that allows deduplication fingerprints and data segments to be shared across multiple StoreOnce appliances, enabling federated deduplication where data deduplicated at one site is recognized and not re-transmitted to another. When upgrading from the older HP D2D StoreOnce and HP Data Protector 6.1 environment described in the scenario, implementing StoreOnce Catalyst with a newer Data Protector version delivers source-side and cross-system deduplication efficiency that the existing platform cannot achieve, directly justifying the upgrade investment.
HP StoreOnce appliances do not support direct installation of a Data Protector Media Agent on the backup system itself - StoreOnce integration with Data Protector occurs through the Catalyst API or VTL/CIFS/NFS interfaces, not through a Media Agent installed on the appliance.
Tape offload via direct-attached tape drives using Data Protector echo copy applies to a different backup topology and is not relevant to upgrading the StoreOnce D2D appliance and Data Protector software described in this scenario.
The HP Data Protector VTL license model applies specifically to virtual tape library configurations and is not the appropriate licensing model for a StoreOnce Catalyst-based federated deduplication upgrade path.
