以太网交换机说明

Data SheetQFX5100 交换机型号QFX5100 系列产品包含四款紧凑型 1 U 型号和一款 2 U 型号，每个型号均提供线速数据包性能、超低延迟以及一组丰富的 Junos OS 功能。

除了高吞吐量数据包转发引擎 (PFE)，具有 8 GB 内存和32 GB SSD 存储的强大 1.5 GHz 双核 Intel CPU 还进一步提升了所有 QFX5100 型号上运行的控制平面的性能。

QFX5100-48S：紧凑型 1 U 10GbE 数据中心接入交换机，带有 48个小型可插拔和可插拔增强型 (SFP/SFP+) 收发器端口和 6 个四路SFP+ (QSFP+) 端口，聚合吞吐量可达 1.44 Tbps 或者每台交换机的吞吐量可达 1.08 Bpps。

QFX5100-48T：紧凑型 1 U 10GbE 数据中心接入交换机，带有48 个三速 (10GbE/1GbE/100 Mbps) RJ-45 端口和 6 个 QSFP+ 端口，聚合吞吐量可达 1.44 Tbps 或每台交换机的吞吐量可达 1.08 Bpps。

QFX5100-24Q：紧凑型 1 U 高密度 40GbE 数据中心接入和聚合交换机，基础密度为 24 个 QSFP+ 端口，可选择使用两个四端口扩展模块扩展至 32 个 QSFP+ 端口。

全部 32 个端口都支持线速性能，聚合吞吐量可达 2.56 Tbps 或每台交换机的吞吐量可达 1.44 Bpps。

QFX5100-24Q-AA：紧凑型 1 U 高密度数据中心交换机，基础密度为 24 个 QSFP+ 端口。

通过添加可选的双宽 QFX-PFA-4Q 数据包流加速器 (PFA) 扩展模块，这款交换机可以变身为智能应用程序加速系统。

或者，通过安装两个四端口 40GbE 扩展模块，QFX5100-24Q-AA 可扩展为支持 32 个 QSFP+ 端口。

该交换机的CPU 子系统通过 32 GB DRAM 四核 Intel CPU 得以增强；通过板载 128 GB 固态驱动器还可以提供额外的存储容量。
