VME-5565反射内存节点卡提供了一个高速、低延迟、确定性的接口,允许在多达256个独立系统(节点)之间以高达170兆字节/秒的速率共享数据。每个反射内存板可以配置64兆字节或128兆字节的板载SDRAM。本地SDRAM提供了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FIFOs缓冲数据,以优化处理器和总线性能,维持高数据吞吐量。
网络传输速率为43兆字节/秒(4字节数据包)到170兆字节/秒(64字节数据包)
动态数据包大小,4到64字节的数据
多达256个节点
连接多模光纤最长300米,单模光纤最长10公里
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(2.12千兆波特串行)
VME传输速率40兆字节
64兆字节或128兆字节SDRAM反射内存

The VME-5565 Reflected 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 of up to 170 megabytes per second. Each reflective memory board can be configured with either 64 megabytes or 128 megabytes of on-board SDRAM. Local SDRAM provides fast read access time to stored data.
Write operations are stored in local SDRAM and broadcast to other reflective memory nodes via high-speed fiber data paths. Data transfers between nodes are software-transparent, so there is no I/O overhead. FIFOs buffered data is sent and received during peak data rates to optimize processor and bus performance and maintain high data throughput.
Network transfer rates from 43 megabytes per second (4-byte packets) to 170 megabytes per second (64-byte packets)
Dynamic packet size, 4 to 64 bytes of data
Up to 256 nodes
The multi-mode fiber is up to 300 meters long and the single-mode fiber is up to 10 kilometers long
Data written to the memory of one node is also written to the memory of all nodes on the network
High speed, easy to use fiber optic network (2.12 gigabit serial)
VME transfer rate 40 megabytes
64 Megabyte or 128 Megabyte SDRAM reflected memory
