What is Hitachi Global-Active Device
Hitachi Global-Active Device (GAD) is a storage-based active-active replication capability for Hitachi enterprise storage systems that supports continuous availability and disaster recovery across two sites. It targets infrastructure and storage teams that need non-disruptive failover for mission-critical applications by presenting a single virtual storage device mirrored between locations. The product focuses on synchronous replication with automated failover behavior at the storage layer rather than application-level backup.
Active-active storage replication
GAD provides an active-active storage configuration across two sites, enabling continued I/O access if one site becomes unavailable. This design supports low recovery time objectives for workloads that require near-continuous availability. It is well-suited to environments that standard backup-only tools cannot protect to the same RTO level.
Storage-layer failover capability
Because replication and failover are implemented at the storage layer, applications can benefit without requiring per-application backup agents. This can simplify protection for heterogeneous workloads running on shared storage. It also aligns with enterprises that standardize on storage-centric resilience patterns.
Integrates with Hitachi storage
GAD is designed to work with Hitachi enterprise storage platforms and related management tooling. This can provide consistent operational processes for replication, monitoring, and storage administration within the same vendor ecosystem. For organizations already using Hitachi storage, this reduces the need to introduce a separate DRaaS control plane for certain use cases.
Not a full DRaaS platform
GAD is primarily a storage replication/availability feature rather than a complete DRaaS service with cloud-based recovery, orchestration runbooks, and multi-tenant management. Organizations may still need additional tooling for automated DR testing, application dependency mapping, and recovery workflows. This can make it less comparable to service-oriented DRaaS offerings for end-to-end disaster recovery management.
Hitachi ecosystem dependency
The capability is tied to supported Hitachi storage systems and architectures. Customers using mixed storage vendors or aiming for hardware-agnostic recovery may face constraints or additional integration work. This can limit portability compared with software-defined backup and recovery platforms.
Synchronous distance constraints
Active-active synchronous replication typically requires low-latency links and careful network design between sites. This can restrict feasible site separation distances and increase connectivity costs. Organizations with long-distance DR requirements may need alternative replication modes or complementary recovery approaches.
