The Abaco Systems VMIPCI-5588-201 is a high-speed fiber-optic reflective memory module for distributed computing systems requiring real-time data synchronization across multiple nodes. Operating at 1.2 Gbaud serial data rate, this PCI bus-compatible board delivers 29.5 Mbyte/s standard throughput or 14.8 Mbyte/s with redundant error-suppression mode. The reflective memory architecture automatically mirrors writes from any node to all networked nodes, maintaining data consistency without processor overhead.
Technical Specifications
