Dell DRAC
Dell Remote Access Controller或DRAC是一個基於頻帶外(out-of-band management)對伺服器進行管理的平台,由Dell公司所開發。該平台可以是外插卡或者是以晶片的形式出現,以晶片的形式則稱之為iDRAC。
DRAC曾是Adrian White的發明專利[1],其提供基於瀏覽器(browser-based)或是指令列(command-line)的兩種介面選項,可以兩者擇一或是兩者兼具,對於伺服器的硬體進行管理與監控。
特性
該控制器有獨立的處理器、記憶體、網路連線以及存取系統匯流排的能力。較為關鍵的功能包括: 電源管理(power management)、虛擬媒體存取(virtual media access)以及遠端主控台(remote console)的能力,這些都可以支援網頁瀏覽器(web browser)或是指令列介面(command-line interface)的方式互動。這給予了系統管理員(system administrator)可以透過該方式從遠端對於伺服器進行設定組態的動作的能力,這對於上百台伺服器的管理者來說無疑是一大福音。
帶有DRAC介面的基板管理控制器(baseboard management controller,BMC)是根據智慧平台管理介面(Intelligent Platform Management Interface,IPMI)第2.0版的標準而設計的。IPMI 2.0允許IPMI 頻帶外界面的使用,例如IPMI Over LAN的功能[2]。
