Abaco Systems PCIE-5565RC-200000 PCI Express (PCIe) Reflective Memory (RFM) Node Interface Card

The Abaco Systems PCIE-5565RC-200000 is a PCI Express node interface card that implements Reflective Memory (RFM) technology for deterministic, low-latency data sharing across distributed systems. The card creates an optical ring-based shared memory network where data written to onboard memory is automatically broadcast to all connected nodes with minimal host processor overhead. This transparent data transfer mechanism eliminates I/O bottlenecks and optimizes system performance for real-time applications requiring sub-microsecond inter-node latency.
