☆型号:VMIPCI-5565 反射式存储器 反射式存储器接口
【产品详情】
概述
PCI-5565 反射式存储器接口允许在多达 256 个独立系统(节点)之间以高达 174 MB/s 的速率共享数据。每个反射式存储器板可配置64 MB或128 MB板载SDRAM。本地 SDRAM 提供对存储数据的快速读取访问时间。写入存储在本地SDRAM中,并通过高速光纤数据路径广播到其他反射式存储器节点。节点之间的数据传输是软件透明的,因此不需要 I/O 开销。发送和接收FIFO在峰值数据速率期间缓冲数据,以优化主机和总线性能,以保持高数据吞吐量。
网络传输速率 43 MB/s(4 字节数据包)到 174 MB/s(64 字节数据包)
动态数据包大小,4 到 64 字节的数据
连接多模光纤长达 300 米,单模光纤长达 10 公里
多达 256 个节点
在一个节点中写入内存的数据也会写入网络上所有节点的内存中
高速、易于使用的光纤网络(串行 2.12 Gbaud)
64 MB 或 128 MB SDRAM 反射式存储器
不建议用于新设计

【英文介绍】
summarize
The PCI-5565 reflective memory interface allows data to be shared between up to 256 independent systems (nodes) at rates of up to 174 MB/s. Each reflective memory board can be configured with 64 MB or 128 MB onboard SDRAM. Local SDRAM provides fast read access time to stored data. Writes 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. Transmit and receive FIFOs buffer data during peak data rates to optimize host and bus performance to maintain high data throughput.
Network transfer rate 43 MB/s (4-byte packets) to 174 MB/s (64-byte packets)
Dynamic packet size, 4 to 64 bytes of data
The multi-mode fiber is up to 300 meters long and the single-mode fiber is up to 10 kilometers long
Up to 256 nodes
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 (serial 2.12 Gbaud)
64 MB or 128 MB SDRAM reflective memory
Not recommended for new designs
