Seamless Replication and High Availability
RSF-1 Layered Over Your Existing Systems
Enable HA, replication, and failover without replacing your current NAS or storage platform.
What RSF-1 Delivers
RSF-1 provides synchronous and asynchronous replication, automatic failover orchestration, and fencing
mechanisms that ensure data consistency during planned or unplanned outages.
Non-Disruptive Architecture
RSF-1 allows the creation of local HA pairs, stretch
clusters, and share-nothing configurations over existing
systems without re-architecting or reformatting data
volumes.
Works with existing storage platforms
No data migration required
Preserves existing configurations

Key Benefits
Non-disruptive deployment
Add HA and replication capabilities without reinstalling the storage OS
Flexible topologies
Local, share-nothing, and stretch cluster options
Automated failover
Monitors node and service health for immediate recovery
Migration path
Supports minimal downtime migrations and rollback options
Architecture & Topologies
Choose the topology that best fits your availability requirements and infrastructure constraints.

Step-by-Step Deployment
Our proven deployment methodology ensures successful RSF-1 implementation with minimal risk.
1. Assessment
Inventory existing OS, storage layout, network
latency, and recovery objectives (RTO/RPO)
2. Design
Select replication mode (sync/async), fencing method, and topology
3. Prechecks
Validate network connectivity, NTP synchronization, and snapshot consistency
4. Installation
Deploy RSF-1, initialize replication, and configure cluster control
5. Validation
Execute controlled failover tests and integrity verification
6. Handover
Deliver documentation, runbooks, and define ongoing monitoring procedures
Prerequisites & Compatibility
Minimum network bandwidth and latency requirements vary by topology
NTP synchronization required across all nodes
Supported filesystems include ZFS, ext4, XFS, and Btrfs depending on OS
Firewall rules must allow RSF-1 control and replication traffic
Mandatory backup snapshot prior to activation for rollback assurance
Migration & Rollback Plan
Secure deployment with fallback options
Data replication to target node before cutover
Controlled switch-over window with test failover validation
Immediate rollback supported through primary failback
