In addition to its built-in replication tools, Hitachi NAS Platform supports the following:
GEfN (GAD Enhanced for NAS) extends Hitachi Vantara's Global Active Device (GAD) technology to NAS workloads, enabling active‑active protection, synchronous replication, and seamless failover for file‑based applications. With GEfN, data is mirrored in real time between two sites, ensuring both server memory and stored data remain fully synchronized. This architecture delivers a zero‑RPO capability, even in the event of a component failure or a complete site outage.
Hitachi Disaster Recovery Solution (HDRS) complements GEfN by simplifying the deployment, management, and recovery of VSP One File 2‑node and 4‑node stretched clusters. Installed within the VSP One File Administrator, HDRS streamlines operations for environments using GAD‑based replication across two sites. It enhances disaster readiness, reduces operational complexity, and accelerates recovery processes.
Together, GEfN and HDRS provide a unified, modern resiliency solution for NAS workloads, combining continuous availability with simplified disaster recovery and operational efficiency.
