反射式内存节点卡提供了一个高速、低延迟、确定性接口，允许在多达256个独立系统（节点）之间以高达170 Mbyte/s的速率共享数据。每个反射式内存板可配置64 Mbyte或128 Mbyte板载SDRAM。本地SDRAM提供对存储数据的快速读取访问时间。写操作存储在本地SDRAM中，并通过高速光纤数据路径广播到其他反射内存节点。节点之间的数据传输是软件透明的，因此不需要I/O开销。在峰值数据速率期间发送和接收FIFO缓冲区数据，以优化处理器和总线性能，保持高数据吞吐量。
网络传输速率为43 Mbyte/s（4字节数据包）到170 Mbyte/s（64字节数据包）
动态数据包大小，4到64字节的数据
最多256个节点
可连接300米以内的多模光纤，10公里以内的单模光纤
写入一个节点内存的数据也会写入网络上所有节点的内存
高速、易于使用的光纤网络（2.12 Gbaud串行）
VME传输速率40 MB
64兆字节或128兆字节SDRAM反射存储器

Overview

The VME-5565 Reflective Memory node card provides a high-speed, low latency, deterministic interface that allows data to be shared between up to 256 independent systems (nodes) at rates up to 170 Mbyte/s. Each Reflective Memory board can be configured with either 64 Mbyte or 128 Mbyte of onboard SDRAM. The local SDRAM provides fast Read access times to stored data. Writes are stored in local SDRAM and broadcast over a high speed fiber-optic data path to other Reflective Memory nodes.The transfer of data between nodes is software transparent, so no I/O overhead is required. Transmit and Receive FIFOs buffer data during peak data rates to optimize processor and bus performance to maintain high data throughput.
    Network transfer rate of 43 Mbyte/s (4 byte packets) to 170 Mbyte/s (64 byte packets)
    Dynamic packet size, 4 to 64 bytes of data
    Up to 256 nodes
    Connection with multimode fiber up to 300m, single-mode fiber up to 10km
    Data written to memory in one node is also written to memory in all nodes on the network
    High speed, easy to use fiber-optic network (2.12 Gbaud serially)
    VME transfer rate 40 Mbytes
    64 Mbyte or 128 Mbyte SDRAM Reflective Memory
