The Huawei OceanStor 18000 storage system is a high-end system with extensive features and capabilities supporting block and file access.  There are two hybrid systems (18500/18800) and the same all-flash models called OceanStor Dorado systems.  Huawei has delivered a succession of storage systems in the high-end, mid-range and entry levels. The system is a scale-out architecture with up to sixteen controllers that are interconnected by PCIe switches.  Storage devices in enclosures are connected with 12 Gb/s SAS.  SSDs and HDDs are supported in any combination.

Connectivity for block access is through Fibre Channel, iSCSI, InfiniBand, and FCoE.  Third party storage can be virtualized behind the OceanStor system allowing centralized management of storage resources and migration of volumes for load balancing, retiring external storage systems, and conversion from thickly provisioned volumes to thin.

Advanced features of the OceanStor system include virtualization, data migration, cache partitioning, quality of service controls, dynamic tiering, and caching with SSDs.  Snapshots, asynchronous and synchronous remote replication, LUN copies, and consistency groups are also included.

File access is supported with an integrated NAS software and use of 10 Gb/s Ethernet.


The Huawei OceanStor 18000 is a set of general purpose storage systems designed for use in multi-tenant environments and for environment with multiple workloads running on the same storage system.  Capacity and performance scaling capabilities widen the usage to most environments.  The availability and resiliency designed into the system plus the advanced features for data protection and business continuity allow customers to place the OceanStor system in demanding environments.

As a system targeted at the high-end enterprise market, features such as quality of service, high performance, and end-to-end data integrity checking are included to meet necessary requirements.

  • Characteristics
    • Block and file access support.
    • Performance – Performance features added include hardware acceleration, scaling of nodes, and use of caching and solid state technology.
    • Availability – Multiple controllers provide non-disruptive HA. The scale-out architecture allows for redistribution of workload when a failure occurs.
    • Replication for BC/DR – Both asynchronous and synchronous remote replication is available as is the ability to make local and remote LUN copies.
  • Applications
    • OceanStor 18000 systems are targeted at applications that use block or file.
    • The OceanStor systems include thin provisioning, snapshots and replication at no additional cost.
    • Additional cost software licenses are available and support the entire suite of software.
  • System environments
    • The Huawei OceanStor systems provide block storage accessed using Fibre Channel (FCP), FCoE, InfiniBand, or iSCSI with standard drivers on host systems. File interfaces are Ethernet with CIFS/SMB and NFS protocol.
  • Deployment and Administration
    • The installation of OceanStor is designed for IT users familiar with storage systems. For customers without the required knowledge, reseller or Huawei service specialists can be used.
    • Management is provided through a management console for multiple nodes, a Replication Director to manage disaster recovery software, and multi-pathing software called UltraPath.
    • Remote Management and Call Home support is also available and is enabled through a Cloud Service.

Evaluator Group Opinion: Differentiating elements for Huawei OceanStor 18000

The Huawei OceanStor 18000 system is targeted to be the primary storage system in high-end enterprise environments with the ability to virtualize third party storage as a means to transition or consolidate to a single platform.  The non-disruptive HA and resilience capabilities are significant features included that are required for the enterprise.

The software and architectural compatibility with other OceanStor systems allows customers to replicate data to and from other OceanStor systems.  This also allows customers to have a seamless management and procedure environment across different platforms and locations.

The Huawei systems suffers from lack of distribution in North America, which would expand opportunities and help with maturity from competitive demands.  Currently, there is no encryption, which has become a checkbox item.  Evaluator Group would like to see more customer use cases and experience with the system for a better understanding of maturity of the system and its features.
