QNAP QuTS MEGA 2.0 Adds Snapshots and Cross-Cluster Mirroring for Scale-Out NAS

QNAP has released QuTS MEGA 2.0, an update to the operating system behind its MEGA Scale-out NAS platform that adds snapshots and Cross-Cluster Mirroring for data protection and disaster recovery. The new features extend the platform’s existing Ceph-based distributed architecture with local point-in-time recovery and replication between separate clusters.

Snapshots Plus an Offsite Mirror

Snapshots allow administrators to capture data at specific points in time, providing a recovery option for accidental deletion, unwanted changes, or ransomware incidents. QuTS MEGA 2.0 pairs this with Cross-Cluster Mirroring, which can replicate snapshots to an offsite MEGA cluster. This gives organizations a secondary copy outside the primary cluster that can be used for recovery when the main site becomes unavailable.

“When managing long-term enterprise data, the real test isn’t just storing it, it’s recovering it immediately when disaster strikes,” said CT Cheng, Product Manager at QNAP. “QuTS MEGA 2.0 builds on our high-scalability architecture by turning data protection and DR into native, platform-level capabilities.”

Ceph Scale-Out Underneath

The update builds on QuTS MEGA’s Ceph-based distributed storage architecture. MEGA deployments can start with three nodes and scale up to 96 nodes within a cluster, with capacity and performance increasing as nodes are added. Automatic rebalancing redistributes data as the cluster changes, while services are distributed across multiple nodes to reduce the impact of individual node failures.

QuTS MEGA also provides two data protection methods depending on the workload. Replication maintains multiple copies of data across the cluster, prioritizing availability and access performance, while Erasure Coding uses parity to reduce the capacity overhead associated with maintaining multiple full copies. Administrators can select between the two based on their storage efficiency, performance, and protection requirements.

High availability extends beyond stored data to services running across the cluster. If a node fails, affected services can migrate to healthy nodes, while self-healing mechanisms reconstruct lost data from replicas or Erasure Coding parity. QuTS MEGA also supports rolling upgrades, allowing system maintenance and updates without taking the entire cluster offline.

QCommander Management

Management is centralized through QCommander, which provides a single interface for administering multiple nodes and clusters. Administrators can deploy clusters, monitor capacity and node health, manage alerts, and perform routine maintenance from the same interface. This creates a consolidated view of the storage environment while reducing the need to manage individual clusters and nodes separately. QuTS MEGA also supports file and object storage with SMB, NFS, and S3 API access, allowing the same scale-out environment to support shared file storage, application data, archives, and object-based workloads.

With version 2.0, QNAP is filling out the software side of its scale-out platform with features expected in large storage environments, particularly around availability, recovery, and centralized management. The combination of Ceph-based scaling, multiple data protection methods, and support for both file and object storage gives organizations flexibility as their storage requirements grow. The protection push spans QNAP’s lineup; on the single-system side, QuTS hero h6.0 brought immutable snapshots and dual-NAS high availability earlier this year.

Availability

QuTS MEGA 2.0 is available for QNAP’s MEGA Scale-out NAS platform. Availability and deployment options vary by region, with configurations offered through QNAP’s sales team.
