OceanStor VTL Solution

Boost Business Agility with OceanStor

Huawei’s OceanStor VTL Solution features powerful emulation capabilities that can virtualize mainstream Physical Tape Libraries (PTLs) and tape drives. It also satisfies data backup needs with global de-duplication and remote replication for data recovery under low bandwidth conditions. Its centralized backup and data recovery capabilities are particularly well-suited for the carrier, government, banking, and electric power industries.

High Performance

  • Supports a maximum of 6 PB of raw storage and 31 TB/hour of backup performance
  • Can emulate 256 tape libraries, 2,048 tape drives, and 500,000 tapes and is compatible with most tape libraries and tape drives
  • Supports common backup software
  • Supports global data de-duplication, eliminating redundant data and lowering bandwidth across multiple sites


  • VTL engines support the active-active mode with multi-node High Availability Services (HAS) architecture
  • Signal-to-Interface Ratio (SIR) engines support the 2+1 cluster mode for overall system reliability
  • Fully redundant storage units ensure reliable reads and writes
  • Redundant Array of Independent Disks (RAID) 6 and hot-spare disks protect data
  • Advanced Encryption Standard (AES) 256-bit algorithm ensures data security during data transfer


  • Offers multiple architectures (integrated, single-node, and multi-node) for different application scenarios
  • Provides several de-duplication modes (front-end inline, back-end post-process, and non-de-duplication)
  • Supports several backup interface protocols and Network Attached Storage (NAS) and VTL interfaces
  • Supports host backup technology, eliminating backup servers and reducing space and power consumption
  • Supports disk spin-down technology to automatically spin down idle disks, dramatically reducing power consumption
