小型SAN的理想之選 – 可提供最高性能、簡便易用的可擴(kuò)展交換機。

1.概述

Brocade 5100交換機專為迅速增長的存儲環(huán)境而設(shè)計 — 在一個高效的1U機架中，可配置24、32或40個端口，結(jié)合了1、2、4和8 Gbps光纖通道技術(shù)。Brocade 5100適用于各種SAN架構(gòu)，每個端口的功耗不超過2.5瓦，因此具有出色的功率和冷卻效率。它還集成了電源和風(fēng)扇組件，以提高環(huán)境性能，降低總擁有成本。

業(yè)界領(lǐng)先的性能和靈活性

為了支持關(guān)鍵任務(wù)環(huán)境，Brocade 5100可提供同類中端SAN交換機中最佳的性能。它采用了一種無阻塞架構(gòu)，最多支持40個端口同時以8 Gbps（全雙工）的速率運行，并且不會出現(xiàn)超量使用現(xiàn)象——總帶寬高達(dá)320 Gbps。此外，增強型Brocade ISL干線合并使一條邏輯鏈路最多可提供64 Gbps的平衡數(shù)據(jù)吞吐量。

為了最大限度地發(fā)揮虛擬服務(wù)器部署的價值，Brocade 5100提供了最高用量者（Advanced Performance Monitoring的一個組成部分）和適應(yīng)性網(wǎng)絡(luò)服務(wù)—一套包括入站速率控制、流量隔離和服務(wù)質(zhì)量（QoS）功能的工具。這些先進(jìn)的功能可幫助優(yōu)化Fabric架構(gòu)的運行，確保關(guān)鍵任務(wù)應(yīng)用可獲得充足的帶寬。為了進(jìn)一步增強靈活性，提升價值，Brocade 5100還提供了集成路由功能，以連接不同F(xiàn)abric架構(gòu)中的交換機。

Brocade 5100包括一種虛擬Fabric架構(gòu)特性，可將物理SAN分成多個邏輯Fabric架構(gòu)。這樣就可以根據(jù)應(yīng)用、業(yè)務(wù)部門、客戶或流量類型實現(xiàn)Fabric架構(gòu)隔離而不會降低性能、可擴(kuò)展性、安全性和可靠性。

為了使用Fibre Channel over Ethernet（FCoE）和Converged Enhanced Ethernet（CEE）整合服務(wù)器連接，Brocade 5100可與Brocade 8000架頂式交換機全面兼容。

高可用性

Brocade 5100是實現(xiàn)災(zāi)難恢復(fù)和業(yè)務(wù)連續(xù)性的可靠基礎(chǔ)，帶有多種企業(yè)級可用性特性，如可熱插拔的冗余集成風(fēng)扇和電源組件等。另外，憑借更快速的系統(tǒng)升級和維護(hù)優(yōu)勢，熱代碼加載和激活功能有助于最大限度地延長應(yīng)用的正常運行時間。

為了支持SAN擴(kuò)展，Brocade 5100允許將服務(wù)器和存儲設(shè)備部署在相距3400公里的地方，進(jìn)而幫助企業(yè)實施最復(fù)雜的業(yè)務(wù)連續(xù)性和災(zāi)難恢復(fù)計劃。

簡單快捷的擴(kuò)展

Brocade 5100易于部署和管理，并且可以輕松集成到新的和現(xiàn)有的IT環(huán)境中。Brocade 5100具有按需端口擴(kuò)展（Ports on Demand）（端口可從24個擴(kuò)展至32或40個）等多種功能，因此，企業(yè)可以根據(jù)需要隨時擴(kuò)展自己的存儲網(wǎng)絡(luò)而不會影響業(yè)務(wù)正常運行。另外，企業(yè)也可以先部署4 Gbps的SFP，然后根據(jù)需要將其升級為8 Gbps的SFP+。

簡化的部署和管理

Brocade交換機借助經(jīng)濟(jì)高效的管理解決方案來優(yōu)化存儲網(wǎng)絡(luò)資源，提高效率，同時降低擁有成本。EZSwitchSetup向?qū)У脑O(shè)計目的是使部署變得更加簡單。在多交換機環(huán)境中，Brocade DCFM Professional可以簡化管理，并對整個Fabric架構(gòu)進(jìn)行監(jiān)控。

Brocade 5100可作為一款全光纖交換機或作為一款Brocade Access Gateway（接入網(wǎng)關(guān)）進(jìn)行部署，能提供到任一SAN網(wǎng)絡(luò)的連接（其默認(rèn)模式設(shè)置是一款交換機）。接入網(wǎng)關(guān)模式采用N_Port ID虛擬化（NPIV）交換機標(biāo)準(zhǔn)，可將光纖通道連接作為邏輯設(shè)備提呈到SAN Fabric架構(gòu)中。如果利用支持NPIV技術(shù)的交換機和導(dǎo)向器進(jìn)行連接，接入網(wǎng)關(guān)模式下的Brocade 5100可以連接到Brocade、McDATA或其它SAN Fabric架構(gòu)。

Brocade光收發(fā)模塊

Brocade 8Gbps交換機需要Brocade光收發(fā)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 8Gbps產(chǎn)品，可以最有效地提高性能，降低功耗，幫助確保關(guān)鍵任務(wù)應(yīng)用的最高可用性。

行業(yè)標(biāo)準(zhǔn)遵從

Brocade產(chǎn)品符合行業(yè)標(biāo)準(zhǔn)，而且采用了普遍接受的工程實踐和流程。
