USS-SN 2-Node Shared Nothing Cluster


 A true, non-disruptive hyper-convergence solution where there is no single point of failure!

Start with only two nodes. USS-SN shared nothing clusters provide the ultimate in high-availability with as few as just two on-premise nodes.  It eliminates the need for shared external RAID arrays, servers, SAN and NAS.  USS-SN can easily and cost-effectively scale to meet challenges of capacity, high availability, CAPEX / OPEX, data transportability and performance requirements.

Each node is protected with dual parity and redundant cache flash technology.   Integrated and embedded SAN (block), NAS (file) shared nothing storage provisioning for virtual and physical machines with associated data services.

Advanced integrated storage, server and network virtualization.  The StoneFly USS-SN node operating with shared nothing architecture provides a fully redundant failover and failback configuration.

NO costly and complex storage arrays for your most demanding applications.

NO single point of failure.
