iSCSI Gateway提供兩個(gè)iSCSI端口來連接支持iSCSI服務(wù)器的IP網(wǎng)絡(luò),以及兩個(gè)2 Gbit/sec光纖通道端口來連接光纖通道SAN或存儲(chǔ)設(shè)備。通過實(shí)現(xiàn)對(duì)關(guān)鍵任務(wù)信息的數(shù)據(jù)塊方式接入,Brocade iSCSI Gateway可以幫助企業(yè)在業(yè)務(wù)需要時(shí)向現(xiàn)有的光纖通道SAN中迅速添加新的服務(wù)器和客戶端。
1.概述
Brocade iSCSI Gateway允許以經(jīng)濟(jì)高效、易于管理的方式建立從服務(wù)器到光纖通道存儲(chǔ)設(shè)備的連接—從而允許遠(yuǎn)程用戶和不同部門接入這些寶貴的資源。因此,即使是最低成本的服務(wù)器也可以連接到現(xiàn)有的SAN。
Brocade iSCSI Gateway采用了緊湊的1U高、半機(jī)架寬的設(shè)計(jì)(集群配置采用全機(jī)架寬設(shè)計(jì))。每個(gè)設(shè)備都提供兩個(gè)iSCSI端口來連接到支持iSCSI服務(wù)器的IP網(wǎng)絡(luò),以及兩個(gè)2 Gbit/sec光纖通道端口來連接到光纖通道SAN或存儲(chǔ)設(shè)備。通過實(shí)現(xiàn)對(duì)關(guān)鍵任務(wù)信息的數(shù)據(jù)塊方式接入,Brocade iSCSI Gateway可以幫助企業(yè)在業(yè)務(wù)需要時(shí)向現(xiàn)有的光纖通道SAN中迅速添加新的服務(wù)器和客戶端。
降低運(yùn)營成本
通過將聯(lián)網(wǎng)存儲(chǔ)的優(yōu)勢擴(kuò)展到連接IP網(wǎng)絡(luò)的服務(wù)器,Brocade iSCSI Gateway可以幫助企業(yè)簡單而經(jīng)濟(jì)高效地?cái)U(kuò)展并整合當(dāng)前的光纖通道SAN基礎(chǔ)架構(gòu),進(jìn)而降低運(yùn)營成本。
智能管理和監(jiān)控
通過一個(gè)基于瀏覽器的GUI,企業(yè)可以輕松管理一個(gè)或多個(gè)Brocade iSCSI Gateway。該GUI也負(fù)責(zé)監(jiān)控每個(gè)存儲(chǔ)和網(wǎng)絡(luò)接口上的流量統(tǒng)計(jì)信息,幫助確保高性能。
高可用性
Brocade iSCSI Gateway可提供帶有故障切換和恢復(fù)功能的雙向“雙活”集群,滿足關(guān)鍵任務(wù)環(huán)境的要求。此外,多條iSCSI連接可以提供從單一網(wǎng)關(guān)到多達(dá)100臺(tái)服務(wù)器的多路徑支持。
SAN標(biāo)準(zhǔn)遵從性
博科產(chǎn)品以符合公認(rèn)工程方案和流程的方式,達(dá)成了與行業(yè)標(biāo)準(zhǔn)的一致。
2.特性
