DRAC stands for Dell Remote Access Controller. It is a hardware device that has its own processor, memory, network interface, and access to the system bus. DRAC provides virtual media access, power management and remote console capabilities. It allows you to access and manage your system remotely over HTTPS, through virtually any browser (though we strongly recommend FireFox on all platforms). DRAC is specifically designed to simplify remote server access to a level that its similar to accessing the local server console in the datacenter.
With remote console a user can see video output of the server and make any input from keyboard or mouse, as if accessing the server on site. Remote console uses Active X or Java application (user selectable, but we highly recommend using Java) which displays a window showing the video output and takes keyboard and mouse input. It is similar to other remote access solutions like Remote Desktop Connection for windows or KVM over IP.
User can reboot (power cycle), turn off and turn on the server even when the core operating system has crashed or shutdown.
DRAC allows a user to mount remotely-shared disk images as if they were connected to the server on site. Together with the remote console, this gives users the ability to re-install an operating system without physically accessing the server, a task which traditionally required local console access to themachine. Administrators can control virtual media through the browser or through the OpenManage tools provided by Dell. Please note: some versions of popularbrowsers restrict certain functionality.
Hardware monitoring is another important feature of Dell Remote Access Controller. A user can see the status of all major hardware components such as power supplies, fans, RAID cards, as well as environmental factors like air and CPU temperatures. A System event Log (SEL) keeps accurate historical records of the events, allowing an administrator to spot recurring patterns and take action before a failure occurs.
