Scale-Out NAS Solution
Highly Available SMB & NFS File Services Built on Ceph
Ambedded Scale-Out NAS delivers enterprise SMB and NFS file services on a single Ceph-based platform, powered by UniVirStor Unified File Services. Start with a few nodes and scale to hundreds of petabytes — capacity and performance grow together as you add servers.
It runs on any x86 or Arm64 server with standard Ethernet, is deployed with one click, and is managed entirely from the UniVirStor Manager web UI — with no vendor lock-in.
Traditional NAS Hits a Wall. Scale-Out NAS Doesn't.
Dual-controller NAS systems scale up until the controller becomes the bottleneck — then you face forklift upgrades, data migrations, and per-appliance silos.
Ambedded Scale-Out NAS takes a different approach: every node you add contributes capacity and performance. File services stay online through disk, host, even rack failures. And because it runs on standard servers with open-source Ceph at its core, you escape both hardware lock-in and proprietary license traps.
| Scale-Up NAS | Ambedded Scale-Out NAS |
| Controller bottleneck | Performance grows per node |
| Forklift upgrades | Expand online, auto-rebalance |
| Per-appliance silos | One namespace to 100s of PB |
| Proprietary hardware | Any x86 / Arm64 server |
Why Ambedded Scale-Out NAS
Linear Scalability
Add nodes to grow capacity and throughput simultaneously — from tens of terabytes to hundreds of petabytes, with no downtime or forklift upgrades.
High Availability by Design
Clustered SMB (CTDB) and NFS with Virtual IP failover. Replication or erasure coding across hosts, with automatic self-healing.
One Platform, Every Protocol
SMB, NFS, and native POSIX (CephFS) — plus block and S3 object storage on the same cluster. One system replaces several silos.
No Vendor Lock-In
Full-stack software on any x86 or Arm64 server with standard Ethernet. No RAID controllers, no proprietary hardware, no capacity-license shock.
Enterprise Identity & Access
Join Active Directory domain and sub-domains in one SMB cluster. Per-export NFS ACLs and role-based access control for the management UI.
Managed From One Web UI
One-click HA SMB/NFS deployment, per-host monitoring, quota alerts, and automated monthly reports — no command line required.
One Cluster. Every File Workload.
Built on CephFS — the distributed file system of Ceph — with production-ready SMB and NFS gateway clusters orchestrated by UniVirStor Manager.
Transparent failover
Clients connect to Virtual IPs. If a node fails, connections are served by surviving nodes automatically.
Tiering in one namespace
Assign NVMe pools to hot project shares and HDD pools to archives — different subvolume groups, same file system.
Multi-tenant ready
Navigable subvolume tree with per-group pools and quotas suits departments, projects, and service-provider tenants.
Enterprise File Services, Production-Ready
SMB for Windows Environments
- ✓One-click HA SMB + CTDB cluster with Virtual IP load distribution
- ✓Active Directory: join domain and sub-domains in a single cluster
- ✓Broad protocol compatibility for legacy and modern clients
- ✓Share-level access control managed entirely in the web UI
- ✓Real-time quota monitoring with threshold alerts
- ✓Per-host CPU and memory monitoring

Cross-Host Protection
Replication or erasure coding; survives disk, host, or rack failure with self-healing.
Snapshots
Scheduled per-directory snapshots with retention; roll back deletions or encrypted files.
Async Mirroring DR
Snapshot-based mirroring replicates directories to a remote cluster, keeping an off-site copy for disaster recovery.
Encryption
Disk-level (OSD) encryption at rest and encrypted network traffic between cluster hosts.
Data Integrity
Automated background scrubbing with tunable schedules.

Scale-Out NAS vs. Traditional NAS
| Traditional Dual-Controller NAS | Ambedded Scale-Out NAS | |
|---|---|---|
| Scalability | Scale-up only; controller bottleneck | Scale-out; capacity + performance grow per node |
| Expansion | Forklift upgrades, data migration | Add nodes online, auto-rebalance |
| Availability | Controller pair failover | No single point of failure; host/rack protection |
| Hardware | Proprietary appliance | Any x86 / Arm64 server, standard Ethernet |
| Protocols | SMB / NFS only | SMB, NFS, POSIX + block & S3 on one cluster |
| Cost model | Per-appliance + capacity licenses | Open-source core, subscription with 5x8 SLA |
| Namespaces | One per appliance (silos) | Single namespace to hundreds of PB |
Deployed in a Day. Supported for Years.
UniVirStor ships as a complete software stack — Linux OS, tuned kernel, Ceph, and UniVirStor Manager — installable from a single ISO. Ambedded backs it with cluster design consulting, deployment service, seamless software updates, and a 5x8 SLA with optional emergency support. Prefer turnkey? The same Scale-Out NAS runs pre-installed on Mars series hardware appliances.
Frequently Asked Questions
What is a scale-out NAS?
A scale-out NAS is a network-attached storage system that grows by adding server nodes to a cluster rather than upgrading a single controller. Each added node increases both capacity and performance, and the system presents a single namespace to clients.
Which protocols does Ambedded Scale-Out NAS support?
SMB (for Windows/macOS), NFS (for Linux/UNIX and virtualization), and native CephFS POSIX access. The same cluster can also serve block (iSCSI, NVMe-oF) and S3-compatible object storage.
Does it integrate with Active Directory?
Yes. A single SMB cluster can join Active Directory domain and sub-domains, supporting complex multi-domain enterprise identity environments.
How is data protected?
Data is distributed across hosts using replication or erasure coding, so the system survives disk, host, or rack failures and self-heals automatically. Scheduled snapshots and asynchronous mirroring to a remote site add protection against accidental deletion, ransomware, and site disasters.
What hardware do I need?
Any x86 or Arm64 servers connected by standard Ethernet. No RAID controllers or proprietary hardware are required. Ambedded also offers pre-integrated Mars series hardware appliances.
How large can it scale?
From tens of terabytes to hundreds of petabytes in a single cluster, expanded online without service interruption.
