Brocade 300是一款24端口交換機，可為入門級SAN奠定經濟而靈活的基礎，也可在核心到邊緣SAN環境中用作邊緣交換機。它可以在高能效、經過優化的1U機型中提供8 Gbps的性能，來支持最苛刻的服務器和虛擬服務器部署。

1.概述

Brocade 300是一款吞吐量達8 Gbit/秒的光纖通道交換機，是專為小型SAN或大型SAN邊緣設計的經濟型入門級解決方案。它使中小型企業可以簡化IT基礎設施，提高系統性能，最大限度地發揮虛擬服務器部署的價值并降低總體存儲成本。

經濟合算的SAN技術

Brocade 300能夠以入門級解決方案的價格提高卓越的性能和強大的功能。它將1、2、4和8 Gbit/秒的光纖通道吞吐量自動偵測與旨在增強光纖架構性能的功能結合在一起。Brocade 300能夠提供如此強大的功能，而每端口的功耗還不到2.5瓦，因此，具有出色的功率和冷卻效率。

Brocade 300采用了一種無阻塞架構，最多支持24個端口同時以8 Gbit/秒（全雙工）的速率運行，并且不會出現超量使用現象——總帶寬為192 GB/秒。另外，增強的Brocade ISL干線合并還可以支持最高吞吐量達64 GB/秒的單一邏輯高速干線。

簡化的管理

借助Brocade EZSwitchSetup安裝向導，可以輕松便捷地安裝和配置Brocade 300，交換機的配置、部署和管理變成了簡單的三步點擊操作。在多交換機環境中，博科網絡顧問軟件（Brocade Network Advisor）可提供全面的數據中心Fabric架構管理功能，包括博科骨干網、交換機和適配器的配置、監控和管理。Brocade 300 可兼容Microsoft Simple SAN，另外還帶有一個可通過簡化固件升級和系統日志文件下載來提高維護簡便性和錯誤記錄的USB端口。

簡單快捷的擴展

Brocade 300易于部署和管理，并且可以輕松集成到新的和現有的IT環境中。Brocade 300具有按需端口擴展（Ports on Demand）（端口可由8個擴展至16或24個）等多種功能，因此，企業可以根據需要隨時擴展自己的存儲網絡而不會影響業務正常運行。另外，企業可以先部署4 Gbit/秒的SFP，然后根據需要升級為8 Gbit/秒的SFP。

高級連接選項

Brocade 5100可作為一款全光纖交換機或作為一款Brocade Access Gateway（接入網關）進行部署，能提供到任一SAN網絡的連接（其默認模式設置是一款交換機）。接入網關模式采用N_Port ID虛擬化（NPIV）交換機標準，可將光纖通道連接作為邏輯設備提呈到SAN Fabric架構中。如果利用支持NPIV技術的交換機和導向器進行連接，接入網關模式下的Brocade 300可以連接到Brocade、McDATA或其它SAN Fabric架構。

Brocade光收發模塊

Brocade 8 Gbit/sec交換機需要Brocade光收發模塊。這種模塊有多種型號，可以滿足不同的速度和距離要求。這些小型可插拔（SFP）模塊最適合用于Brocade 8Gbit/sec產品，可以最大限度地提高性能，降低功耗，幫助確保關鍵任務應用的最高可用性。
