Barun Agarwala, Enterprise Architect at NTT, explains how Cloudian object storage is integrated into their service offerings.


NTT’s collaboration with Cloudian and HPE for storage services

  • Barun Agarwala, Enterprise Architect, NTT

NTT is standardized on software defined resources on HPE hardware.  This deployment is currently 1 petabyte of storage.

Cloudian benefits cited include:

  • Start small on 3-node and scale without disruption
  • Fully peer-peer architecture
  • Multi-tenancy, for secure access by tenants
  • S3-compatible API
  • Quality of Service controls to ensure SLAs
  • Future proof, with the ability to later add nodes with updated technology
  • Use Cloudian APIs to provision and configure storage within NTT’s automation framework

Common use case:

  • Backup target.
    • “This provides better backup SLAs and fast recovery, while providing offsite storage for DR.”
    • “With tape, it takes time for tapes to be transported offsite, and then called back if needed.”


  • Geo-distribution of storage
  • File-based storage services

Partnering with HPE and Cloudian:

  • “HPE was an excellent partner, providing good advice on hardware and software.”
  • “Cloudian has also been a very good vendor. They helped us with design, with the delivery, and are still with us in the operations phase.”
