Unlocking the Power of MoSMB’s Active-Active Scale-Out Cluster

Modern enterprises demand file storage solutions that are not only high-performing but also highly available, scalable, and easy to manage. MoSMB’s active-active scale-out cluster architecture addresses these needs, delivering true enterprise-grade SMB (Server Message Block) file services for demanding business environments.

What is MoSMB’s Active-Active Scale-Out Cluster?

At its core, an active-active scale-out cluster means every node in a MoSMB cluster is fully operational and can serve SMB client requests simultaneously. This architecture offers a significant leap over legacy active-passive or single-node configurations, eliminating bottlenecks and single points of failure.
Clients can connect to any node in the cluster and seamlessly access shared files, regardless of where the data physically resides.

Key Features of MoSMB’s Scale-Out Cluster

1. Linear Scalability
Easily expand from as few as three nodes up to 100 nodes in minutes using automated Ansible playbooks, allowing IT teams to match growth with business demand.

2. Active-Active Architecture
All nodes actively participate in serving client requests. Users benefit from aggregated throughput and resource utilization—perfect for high-traffic, collaborative workloads.

3. Seamless Failover
MoSMB ensures continuous data availability by supporting transparent failover of active SMB sessions. If a node is upgraded or taken offline, connections automatically redirect to other nodes, providing zero downtime during maintenance or failures.

4. Unified Namespace
Each SMB share is exported identically from every node, allowing any client to access the same data from any cluster endpoint.

5. Cluster-Aware Locking and Leasing
Advanced file locking and leasing mechanisms operate cluster-wide, making complex workflows and concurrent access—such as multiple users editing or opening the same files—smooth and consistent across all nodes.

6. Flexible Configuration
Centralized configuration management (via mosmb.json and mosmbcli) lets you easily update cluster settings, authentication, shares, and more, distributing changes across all nodes effortlessly.

7. Filesystem Agnostic
Integrates with any POSIX-compliant filesystem, enabling true flexibility in storage choice.

8. Proven Stability and Performance
With production deployments ranging from 3 to 54 nodes—and robust field operations for over three years—MoSMB clusters deliver zero downtime and enterprise-grade reliability.

Why Choose Active-Active Scale-Out with MoSMB?

• Enhanced Performance: Workloads are distributed across all nodes, increasing throughput and minimizing latency—no single node becomes a bottleneck.
• High Availability: Redundancy and automatic failover guarantee uninterrupted file access, even during planned upgrades or node failures.
• Effortless Growth: Scale capacity and performance horizontally by simply adding nodes—no disruptive migrations or reconfigurations needed.
• Simplicity: With user-level implementation (no kernel modules), MoSMB is simple to deploy and maintain across diverse Linux environments.

Conclusion

MoSMB’s active-active scale-out cluster redefines what modern SMB file serving can be—delivering the performance, flexibility, and resilience enterprises need to power mission-critical workloads.
Whether you’re seeking to modernize file storage, support global collaboration, or achieve seamless scalability, MoSMB’s cluster architecture is ready to elevate your infrastructure.
