Don't think you'll have much luck. DataDomain is the only Dedup Appliance supported by Avamar. Avamar is its own Backup/Dedup Appliance. DD Support was added because they're both from DellEMC. Avamar Clients also have the DDboost library integrated so they can write their backups directly on the DD (as does Veeam). Metadata is still stored on the Avamar Node/Grid. There's no equivalent to DDboost on a Quantum DXi, for example. That appliance has some extra integration with NetBackup (OST/DAE) or Veeam, where the Veeam Data Mover service can run directly on the DXi.
Hi All; I am looking for any storage like as Quantum, HP,  that can be compatible with avamar 18.1 (as like as Data Domain can connect to avamar to backup data). Thank you.
