Benefits

The public cloud offers flexibility, ease of use, and reliability, driving many enterprises to adopt cloud computing. However, a complete and rapid cloud migration is challenging for organizations that rely on traditional storage arrays. This move can require major changes to systems and applications, introducing significant risk. Additionally, data residency requirements often mandate that sensitive data remains in a specific physical location. For these reasons, an increasing number of enterprises are choosing a hybrid cloud approach for their digital transformation.

As an integrated hardware and software appliance, HCSA integrates with Alibaba Cloud storage services and combines the advantages of public cloud storage and traditional storage arrays:

  • Simplicity

    Use HCSA like a standard on-premises device without changing your IT architecture. It unifies local and cloud storage, eliminating protocol compatibility issues.

  • Flexibility

    Seamlessly integrate with Alibaba Cloud storage services. Leverage the advantages of the public cloud, including easy scaling, rapid deployment, and pay-as-you-go pricing to meet evolving business demands.

  • Efficiency

    Automated cloud replication creates data copies both locally and in the cloud for high availability. If the array fails, your data remains accessible from the cloud. If the network connection fails, your data remains accessible from the local array.

    The cloud cache feature ensures low-latency application performance. Frequently accessed hot data is cached locally for high-speed access, while cold data is stored in the cost-effective and scalable public cloud.

  • Reliability

    HCSA features a fully redundant hardware design. It supports data encryption, integration with Active Directory (AD) and Lightweight Directory Access Protocol (LDAP), and access control lists (ACLs). Data in the cloud is protected with multi-replica, cross-region distribution, providing 99.999999999% (eleven 9s) data durability. Comprehensive data consistency checks ensure your data is secure and reliable.

HCSA provides a rich set of features to achieve these goals:

  • Automatically sync data to the cloud based on policies for cloud backup and disaster recovery.

  • Ensure fast data access and efficient storage use with automatic cloud replication and cloud caching.

  • Improve data mobility between on-premises and cloud storage with data compression and data deduplication.

  • Support a comprehensive set of host protocols, including FC, iSCSI, FCoE, NFS, CIFS, and Cinder.

  • Provide rich enterprise data services such as multi-version snapshots and replication.

  • Protect critical enterprise applications with gateway-free smart active-active disaster recovery.

  • Improve the utilization of existing arrays and reduce total IT costs with heterogeneous virtualization.

  • Enhance array performance and capacity with multi-controller scaling.

  • Ensure security and reliability with a fully redundant design that supports rack deployment in your data center.

  • Create read-write clones of a volume.

  • Ensure business continuity through online failover and recovery if a controller fails.

HCSA brings the cost-effectiveness and scalability of the public cloud to your on-premises data center, enabling seamless data mobility between your on-premises environment and Alibaba Cloud.
