GS-Cube8V2: Small footprint certified Microsoft Windows Server 2019 2-Node Appliances

2. Generation of 2-Node Clustered Hyper-Converged Appliances
Cube8V2 S2D 2 node HyperV 2019

Zstor 2-Node HCI solutions are low-cost, small, hyper-converged appliances designed specifically as integrated computing, networking and storage infrastructure. They are nearly linearly scalable to simplify and maximize the deployment of Microsoft applications, virtualization, data protection and hybrid cloud services. They are designed to optimize the full scope of Storage Spaces Direct within Windows Server 2016/2019 to make software-defined storage as shared nothing storage affordable to everyone.

More CPU power through INTEL® Xeon® Scalable CPU, more memory up to 768GB RAM, more virtual machines. The 2.generation of our GS-Cube8 was also inspired by the Microsoft Server Team Project Kepler-47, but goes beyond that approach. Since customer ask for more performance we developed a small footprint high available 2 Node Hyper Converged Appliance Solution based on Windows Server 2016/2019 Storage Spaces Direct. Customer are able to run the same Storage and HCI operating system as in their datacenter in remote / branch offices or in departmental use. Because of the ultra quiet cooling the systems can be used in normal office environments with no need for extra IT housing.

Azure Stack HCI certification

Our high-availability 2-node cluster solution also has undergone Azure Stack HCI certification program from Microsoft for Windows Server 2019. This allows you to run virtualized applications in a modern hyperconvergent infrastructure (HCI) that is fully certified by Microsoft. Due to our cooperation with Microsoft and the system’s successful completion of the severe validation program, this solution is also listed in the Azure Stack HCI catalog.
