Introducing RONNIEE Express Fabric 
The "In-Memory Network"
 The RONNIE Express “In Memory Network” unlocks an extremely compelling alternative to current design techniques using a cost-effective and disruptive architecture. The new “In Memory Network” is designed to remove all the limitations of today’s interconnection fabrics, providing for the first time, military grade reliability to all. RONNIEE Express provides an ultra-fast and transparent path for any networked application to supercharge performance and acceleration. Through our technology, Remote memory accesses are transparent to the requesting processes and eliminate the bottlenecks related to traditional RDMA support. There is no protocol stack involved in remote memory access, resulting in communication latencies as low as 800s of nanoseconds (for system to system latency). 
PCIe bus memory transactions are converted into corresponding (distributed non transparent memory bridging) dNTB memory mapped transactions allowing physically separated PCIe buses to appear as one.

RONNIEE Express allows direct mapping of memory accesses from the I/O bus of a local machine to the I/O bus and into the memory of a remote machine 
(Memory to memory operations are driven by Hardware )
A3CUBE’s RONNIE Express uses a unique combination of hardware and software. It combines multiple 20 or 40 Gbit/s channels with less than one microsecond latency and dramatically improves overall inter-system communication for advanced direct inter-servers and inter-processors connections.
The RONNIEE Express Fabric simply uses an application-transparent mechanism, as the main communication model between two or more hosts.
The advantage of this architecture is that once the memory mapping is defined, each active network interface has direct access to the "In Memory Network" without operating system interventions, resulting in the lowest possible communication latency, at any level, even for user-level software. 

The RONNIEE Express Fabric
RONNIEE Express is a Real Fabric

There is a big difference between the term “interconnect” and “fabric” 
Many technologies that are touting themselves as fabric solutions are little more than a simple serial interconnect with few of the features that are required by the demanding real world applications of today.
The processor bus and peripheral bus as PCI and PCI Express lack basic features that are present in modern communication fabrics: Source directed routing, message passing protocol, classes of services, topological flexibility and much more.
A communication fabric must be able to function as a simple point-to-point interconnect but also scale to handle thousands of nodes functions. 
RONNIEE Express extends the capabilities of PCIe by adding all these features in order to realize a real interconnection “fabric” and not a simple interconnect, providing all the requirements of today’s applications with massive scalability.  
The RONNIEE Multi-dimensional Topology
Connecting nodes using a 3D Torus configuration means that each server in the cluster is connected to the adjacent using short cables. The signal is routed directly form one node to another and importantly one with no need for costly and complex external switches.
This configuration allows the addition of nodes to a clustered system without any impact on its performance.

RONNIEE Express distributed switching
Switches are potential point of failure.  Eliminating the external switches, we improve the reliability of the fabric creating a dataplane with no single point of failure. The 3D approach makes the RONNIEE express fabric more agile, more prompt to react to failures: if a connection or an entire node fail, the affected communication can be routed in many different directions. 
Eliminating costly and power-hungry TOR, spine and Leaf switches, as well the related rack chassis and cooling systems, RONNIEE express realizes the perfect backend for modern scale-out systems and real hyper-converged machines, it contributes, also, to reduce installation costs, energy consumption and space.
