产品详细介绍Brocade FastIron CX系列 以太网中低端交换机
Brocade FastIron CX系列是高性能、可扩展而且灵活的企业园区接入交换机，可以在紧凑的机型中实现下一代融合应用。FastIron CX系列交换机有24端口和48端口两种型号，支持PoE和PoE+，可以大大提高网络边缘的性能和智能水平。
功能强大、可扩展而且灵活的园区网接入解决方案
Brocade FastIron CX系列交换机可以提供当今企业园区网所需的更高性能、可扩展性和灵活性。利用多种先进的功能，这些交换机可以在灵活的1U机型中向网络边缘提供高性能和智能，帮助降低基础架构和管理成本。
FastIron CX交换机是专为提供线速无阻塞性能而设计的，有24端口和48端口两种型号，和PoE（以太网供电）及非PoE两种版本。利用内置的16 Gbps堆栈端口和Brocade IronStack技术，企业可以将最多8台交换机堆叠为一台有384个端口的逻辑交换机。PoE型号支持新的Power over Ethernet Plus（PoE+）标准，为边缘设备提供30瓦的电源，支持下一代园区应用。
其它主要特性包括：
• 业界第一款Power over Ethernet Plus（PoE+）交换机，带有堆栈功能和冗余电源
• 高可用性模块化设计，带可热插拔冗余电源和可拆卸式风扇
• 可选的万兆以太网（10 GbE）端口，可建立从可堆栈解决方案到聚合/核心层的高速连接
• 基于硬件的sFlow流监控功能，由Brocade IronShield 360提供实时保护，防止基于网络和主机的攻击
• Brocade IronView Network Manager（3.2或更高版）、基于Web的网元管理和丰富的命令行工具提供简化、全面的管理
下一代园区融合
FastIron CX交换机可以通过网络连接同时提供电源和数据传输功能，从而为园区边缘设备提供了一种单线缆解决方案，这些设备包括Voice over IP（VoIP）电话、传统IP电话、监控摄像头和无线接入点。
这些交换机可支持新的PoE Plus标准（802.3at），为每台设备提供30瓦的电源。这种强大的解决方案可以简化下一代解决方案的布线，如视频会议电话、水平/垂直转动摄像头和802.11n无线接入点。
24端口的FastIron CX交换机可以为每个端口提供Class 3（15.4瓦）或PoE+（30瓦）电源，而48端口型号可以为每个端口提供Class 3电源或向26个端口提供PoE+电源。这些交换机可以同时为PoE和PoE+设备供电而不超出交换机820瓦特的功率预算。
供电设备的即插即用式运行
FastIron CX交换机可以支持IEEE 802.1AB Link Layer Discovery Protocol（LLDP）和ANSI TIA 1057 Link Layer Discovery Protocol-Media Endpoint Discovery（LLDP-MED）标准，可以帮助企业部署可互操作的多厂商解决方案，实现统一通信。
LLDP和LLDP-MED为配置、发现和管理网络架构提供了一种标准、开放的方法。这两种协议可实现网络运行的简化和自动化，进而帮助降低运营成本。
简化的高性能堆栈
FastIron CX交换机带有两个专用的16 Gbps堆栈端口，可提供简单而强大的扩展功能，满足网络边缘的未来增长需求。利用IronStack技术，最多可将8台FastIron CX交换机堆栈成一个只有一个IP地址的逻辑交换机，以简化管理。
整个堆栈可以提供64 Gbps的交换带宽，因此基本上可避免交换机间瓶颈。专用的堆栈端口可在机架内提供可扩展性，这样就可以将可选的10 GbE端口解放出来，用于建立到聚合或核心层的高速连接。
来自堆栈内不同成员的10 GbE端口可以合并起来，以优化性能和可用性。为了进一步提高灵活性，IronStack还支持使用10 GbE端口，通过光缆布线在机架间、楼层间和大楼内实现交换机堆栈。
一个堆栈中最多可以集中8条10 GbE链路，从而在布线室和聚合层之间提供80 Gbps的总带宽。
更低的功耗
在当今快速增长的业务环境中，企业需要最大限度地降低整个IT基础架构的功耗。FastIron CX交换机可以智能地控制电源使用，将“绿色”计划扩展到布线室。
提供给园区设备的电源可以自动协商，提供正好能满足设备需求的电源。如果设备进入睡眠模式，它们的功耗会更低，需要网络提供的电源更少，因此可以最大限度地降低园区环境中的功耗。
高可用性和企业级安全性
FastIron CX交换机通常专用于数据中心级解决方案，可以选配可热插拔、负载分担的冗余双电源。它的模块化设计还带有可拆卸的风扇组件。这些特性使它能够以更小的占地面积为园区布线室提供更高的可用性。
其他设计特性包括进风口和出风口温度传感器和风扇转速检测，可帮助迅速检测到异常运行条件或故障，进而帮助最大限度地缩短平均修复时间。
此外，FastIron CX交换机还采用了Brocade IronWare操作系统，可以为第2层和第3层业务提供丰富的安全功能，实现网络接入控制（NAC）和拒绝服务（DoS）攻击防护。
基于开放标准的简单、安全管理
FastIron CX交换机可以提供基于标准的简便管理功能，帮助企业节约管理时间，减轻工作量，同时有效地保护自己的网络。主要功能包括：
• 通过自动配置实现的更简便部署
• 通过Brocade IronView Network Manager实现轻松管理
• 通过符合行业标准的命令行界面（CLI）实现的开放管理
• 带外管理
以太网存储流量的理想选择
当代的iSCSI SAN环境需要高性能网络来可靠地将存储的数据块发送到服务器上。FastIron CX交换机可以提供强大的功能来支持使多条万兆以太网链路都疲于应付的服务器。
